Add build-time SVG transcoder with SMIL animation support#5042
Merged
Conversation
New maven/svg-transcoder module parses SVG files with the JDK's StAX reader (no Batik dependency) and emits Codename One Image subclasses that render via the Graphics shape API. Covers shapes (rect, circle, ellipse, line, polyline, polygon, path including arcs), groups with affine transforms, linear gradients via LinearGradientPaint, and SMIL animations (animate, animateTransform, set) interpolated against wall-clock time. A new TranscodeSVGMojo runs in generate-sources, scans src/main/svg, and emits one class per SVG into target/generated-sources/svg plus an SVGRegistry class. The runtime base class lives at com.codename1.svg. GeneratedSVGImage; Resources.getImage now falls back to a global registry populated reflectively from the generated SVGRegistry so transcoded images appear under their source filename for any Resources opened in the VM. The hellocodenameone module includes five SVG fixtures (static shapes, gradient, path, two animated) and two screenshot tests; animated images expose setAnimationTimeMillis so tests can pin the frame deterministically.

The lazy Class.forName/getMethod/invoke probe in Resources.getImage made java.lang.reflect.Method.invoke and java.lang.Class.getMethod reachable through Resources, which on iOS pulled symbols ParparVM's static reachability analyzer otherwise strips. The generated Resources.m then emitted calls to virtual_java_lang_Class_getMethod___..., virtual_java_lang_reflect_Method_invoke___... that the linker never sees, failing the iOS / native-ios / packaging jobs. Removes the auto-probe and instead documents the one-line SVGRegistry.install(resources) call required after loading a theme. The generated registry's install method still populates both the per-instance map and the global fallback, so a single startup call covers all Resources opened in the VM. JavaSE-only behavior is unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

CI's quality report failed on ControlStatementBraces, MissingOverride, and OneDeclarationPerLine for the new SVG runtime + transcoder mojo. Wrap every single-line if/for body in braces, split the px/py decl, and add the @OverRide annotation on MutableResource.setImage that became required once Resources gained the matching method. No behavioral change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The previous commit swept in IDE configs, the local quality report and unrelated website syndication scripts that were untracked in the working tree. Drop them from version control so the PR contains only the SVG transcoder change.

CLDC11's java.lang.Math intentionally has no acos -- the SVG-arc decomposition in svgArc was reaching for Math.acos, which made the Ant CodenameOne core build fail under the bootclasspath that mirrors CLDC's surface (build-test 8 / 17 / 21). Route through MathUtil.acos, the CN1 helper that already implements the missing trig functions identically on every port.
The Ant CodenameOne core build uses javac with ASCII encoding, so em-dashes (--), arrows (->) and similar typographic flourishes I had sprinkled through doc comments fail with "unmappable character for encoding ASCII" on the Android port and CodenameOne core build steps (build-test 8 / 17 -- build-test 21 happens to pass because Maven sets UTF-8). Replace every em-dash with --, smart quotes with ASCII quotes, arrows with -> / <-, etc. Generated output is unchanged.
…ckage, core-unittests Move GeneratedSVGImage from com.codename1.svg into com.codename1.ui (one class doesn't justify its own package, and the runtime already lives alongside Image/Graphics there). Drop com.codename1.svg entirely. Wire animation timing through com.codename1.ui.animations.AnimationTime instead of System.currentTimeMillis(). The image still captures a per-instance "first paint" timestamp so animations begin at t=0 when drawn, but every read of the clock now flows through AnimationTime.now() so AnimationTime.setTime(...) in a test pins the entire animation graph deterministically. The old setAnimationTimeMillis()/resetAnimation pair becomes redundant -- removed setAnimationTimeMillis, kept resetAnimation for callers that want to rebase t=0 explicitly. Make scaled()/getWidth()/getHeight() actually carry caller-supplied dimensions: scaled(w, h) returns an SVGScaledView wrapper that reports the requested size from getWidth/getHeight (so component layout sees the right box) and delegates rendering + animation state to the source. The old "return this" was wrong -- it silently broke any layout that asked for a different size. Default size is now a function of device density: the SVG-declared intrinsic width/height are treated as design pixels at DENSITY_MEDIUM and scaled by the device density so icons look right on high-DPI screens. Display lookup is wrapped in a safe fallback for the unusual case where the image is constructed before Display.init. Animated screenshot test (hellocodenameone) now pins AnimationTime so spinner / pulse capture is deterministic instead of relying on the removed setAnimationTimeMillis hack. Add maven/core-unittests/.../GeneratedSVGImageTest -- 18 JUnit 5 tests exercising the DPI sizing heuristic, scaled-view semantics, AnimationTime integration (first-paint capture, advancement, rewind clamp, reset), and the static SMIL helpers (progress, lerp, lerpColor, lerpValues, svgArc). This runs in the PR CI build-test job, which the hellocodenameone screenshot tests don't (they run in scripts-ios.yml / ios-packaging.yml when scripts/hellocodenameone/** changes -- not in the same job). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The hellocodenameone screenshot harness doesn't auto-discover BaseTest subclasses -- DEFAULT_TEST_CLASSES is an explicit array (line ~140-225). Without an entry the runner skips the class entirely, which is why neither the static nor animated SVG screenshot landed in any artifact even though the source compiles and CI passed. Insert the two SVG tests right after the CSS filter test and before the orientation lock test (which must remain last because orientation state leaks across subsequent screenshots). Move the AnimationTime.reset() in SVGAnimatedScreenshotTest into a proper cleanup() override so the pinned clock survives the ~1.5s screen- shot capture window but is released before the next test runs. Avoids a state leak into OrientationLockScreenshotTest.
LinearGradientPaint.paint(g, x, y, w, h) ignores x/y and rasterizes the gradient through its absolute startX/startY/endX/endY into the supplied rectangle. Calling g.setColor(paint) then g.fillShape(circle) therefore paints the gradient through the circle's full bounding box, not the circle itself -- the test's gradient circle looked like an empty stroke because the fill silently never landed inside the outline. Fix in the codegen: for gradient fills, push the clip, set the shape as the clip, then invoke paint.paint(g, bx, by, bw, bh) within the path's bounding rectangle, then pop the clip. Solid-color fills still use the fillShape(path) path which behaves correctly. Stroke emission is unchanged. Reorganised emitPaintSet / emitGradientFill so the two branches no longer share half-stateful alpha bookkeeping. Replaced SVGAnimatedScreenshotTest with an AbstractAnimationScreenshotTest subclass so the animated SVGs are captured as a 2x3 grid of frames across one cycle. AnimationTime is advanced per cell by the base class; the SVG images read their offset from AnimationTime.now(), so each cell shows a different rotation (spinner) and radius (pulse) -- proving the animation is actually running, not just rendering the first frame. Skip the two SVG screenshot tests on the JS port: the existing ~150s browser-lifetime budget is tight (it forces other heavy tests to the timeout list), and adding both an animation grid and a static render tipped it over today. Revisit when the JS port harness gets a longer-lived window.
Two regressions called out on the latest screenshots: 1. Rendered shapes look stair-stepped (no antialiasing). The drawImage path on GeneratedSVGImage now flips g.setAntiAliased(true) for the duration of paintSVG and restores the previous value in the finally block. Vector output looks the same as the rest of the framework's antialiased rendering after this. 2. The pulsing circle's <animate attributeName="opacity"/> never landed because the codegen baked style.getOpacity() in as a static Float at build time. Resolve the element opacity through animFloat() the same way fill-opacity / stroke-opacity already do, so a SMIL opacity animation drives the alpha multiplier on every paint. The pulse now actually fades. Opacity flowing through the alpha expression also keeps gradient fills honoring the animated element opacity since emitGradientFill takes the same AnimatedFloat parameter. iOS Metal still shows a triangle for the gradient circle and the spinner doesn't appear -- those reproduce only on Metal and look like port-level setClip(Shape) / setTransform issues; tracking separately.
End-to-end integration so SVG support behaves like the rest of CN1's
image pipeline:
CSS pipeline
- Patch maven/css-compiler/.../CSSTheme.getBackgroundImage to recognize
url(*.svg). Instead of trying to rasterize the XML (which throws and
was the blocker on this path), it registers a 1x1 transparent PNG
placeholder under the SVG filename. The theme.res keeps a reference
the runtime can later overwrite.
- Honour cn1-source-dpi on the same rule that references the SVG (the
established CN1 multi-image hint). The transcoder mojo scans the
surrounding rule for this declaration and bakes the resulting
density into the SVGRegistry's install() call so theme.getImage()
returns an instance sized as if the SVG were a density-tagged
multi-image bucket.
Build flow
- Add transcode-svg to the cn1app-archetype's common/pom.xml so every
new project picks it up. The mojo now scans both src/main/svg AND
src/main/css (so SVGs can live next to the theme.css that references
them) and emits placeholders into target/css-resources alongside the
Java sources / registry.
- Walks each CSS rule's block for url(*.svg) + cn1-source-dpi and
exposes the result to the codegen via a new sourceDensity field on
SVGTranscoder.GeneratedClass. The generated registry then calls
`new Spinner(50)` instead of `new Spinner()` when the CSS said
cn1-source-dpi: very-high.
Runtime
- GeneratedSVGImage gets a second constructor that takes an explicit
source density. The DPI-aware sizing heuristic now scales by
deviceDensity / sourceDensity rather than always assuming
DENSITY_MEDIUM, so an SVG marked very-high renders smaller on a
high-DPI device than an SVG with no hint.
- The generated subclass exposes both constructors (no-arg + int) so
registries / user code can pick the right one.
Tests
- Move the hellocodenameone SVG fixtures from src/main/svg/ to
src/main/css/ -- the natural place alongside theme.css.
- Replace the two screenshot tests' Java-side `new Spinner()` hardcode
with the developer-facing flow:
SVGStaticScreenshotTest.prepare() calls
com.codename1.generated.svg.SVGRegistry.install(globalRes);
SVGAnimated/Static both pull images via
Resources.getGlobalResources().getImage(name);
This exercises CSS -> placeholder -> transcoded class -> getImage
end-to-end.
- theme.css now declares five style classes that reference the SVGs
with cn1-source-dpi: very-high, demonstrating the CSS hint flowing
through to the runtime size calculation.
Docs
- New docs/developer-guide/SVG-Transcoder.asciidoc documents the
feature: source layout, CSS hints, sizing rules, feature coverage,
troubleshooting.
Simulator verification
- mvn process-classes on hellocodenameone-common now compiles the
theme.css to a theme.res that contains the SVG filenames as image
entries; the SVGRegistry overrides those at install() time, so
Resources.getImage(name) returns the SVG.
Many SVGs in the wild ship with arbitrary intrinsic dimensions (a
1024x1024 export of what's really a 24x24 icon, a 600x600 export of a
16x16 control, etc.), making the cn1-source-dpi heuristic the wrong
tool for the job. Add two CSS attributes that pin the rendered size in
millimeters so the icon comes out the same physical size on every
device regardless of what the SVG declares.
HomeIcon {
background: url(home.svg);
cn1-svg-width: 6mm;
cn1-svg-height: 6mm;
}
Routes both values through Display.convertToPixels() at install time,
matching the way `font-size: 3mm` works elsewhere in CN1 CSS.
Implementation
- GeneratedSVGImage gains a third protected constructor taking explicit
pixel dimensions, plus a public static mmToPixels(float) helper.
- The codegen emits three constructors per generated subclass -- no-arg
(default DENSITY_MEDIUM), int sourceDensity (cn1-source-dpi), and
float widthMm/heightMm (cn1-svg-width/height). SVGRegistry picks
whichever the CSS rule declared.
- TranscodeSVGMojo now parses cn1-svg-width / cn1-svg-height alongside
the existing cn1-source-dpi extraction. Explicit millimeters take
precedence over density bucket; density beats no hint.
- CSSTheme acknowledges the two new properties as known no-ops so the
parser stops logging "Unsupported CSS property" warnings.
Tests
- Two new core-unittests cover the explicit-pixel constructor and the
mmToPixels DPI conversion. Two new transcoder tests cover the
3-constructor codegen plus the registry's mm > density > default
precedence.
- hellocodenameone's theme.css switches the two animated SVGs to use
cn1-svg-width / cn1-svg-height: 12mm so the demo proves the new
path -- generated registry now emits
`new SpinnerAnimated(12.0f, 12.0f)`.
Docs
- Developer guide reorganized around the three sizing mechanisms in
precedence order. Recommends millimeter dimensions for any SVG with
non-standard declared width/height (which is most of them).

Developer Guide quality checks: |
… docs Seamless installation - Resources gains a tiny OpenHook API. Generated SVGRegistry registers itself in a static initializer that fires the first time any Resources opens (Resources.probeSVGRegistry does Class.forName on the literal class name). ParparVM treats the literal class reference as a reachability root, so iOS / Android builds include the generated class without any reflective getMethod / invoke. The registry then registers an OpenHook that fires on the same load, replacing the CSS-compiler placeholder PNGs with the transcoded SVG instances. - Drops the explicit SVGStaticScreenshotTest.installSVGRegistry() call from both screenshot tests -- the registry is now seamless for app code; calling install() by hand defeats the test. Fail-fast dimensions - GeneratedSVGImage's pixel-dimensions constructor now throws IllegalArgumentException for width/height < 1 instead of clamping to 1. Same for SVGScaledView's scaled(w, h). mmToPixels also throws if the requested mm value resolves to 0 pixels (a 0.something mm cn1-svg-width hint that rounds away) -- silently producing a 1px result was always a debugging trap. SVG text rendering - Add SVGText model + parser path: <text> with x, y, font-family, font-size, font-weight (including numeric 700+ = bold), font-style, text-anchor (start/middle/end). <tspan> children are flattened into the parent text's content (single style per <text>; per-run styling is a follow-up). - Codegen emits g.drawStringBaseline through a Font.derive of the default font sized in user units, with anchor-aware x positioning via Font.stringWidth. Fill / opacity / animation flow through the same paths as shape fills. Docs - Strip "introduced in 8.0" and v1 language from the developer guide per project convention. Replace the inaccurate "Codename One has historically supported SVG" claim (it only ever worked on J2ME and the JavaSE simulator) with an accurate reference to the legacy flamingo-svg-transcoder. Document the seamless install path so the guide stops telling users to write SVGRegistry.install() manually. - Note text and clip-path coverage in the feature matrix. Tests - Two new parser tests for text + numeric font-weight. - New CompileGeneratedSourceTest case ensures the text codegen produces a class that compiles against the real CN1 Font / Graphics surface.
Hellocodenameone test coverage - logo_text.svg exercises the new <text> path -- anchored middle/end rendering, font-weight bold, font-style italic, multi-color fills, on top of a rounded-rect frame. Catches regressions in font derivation, anchor positioning, and styled text in the same SVG. - wave_path.svg targets the path mini-language: S smooth-cubic reflection, T smooth-quadratic reflection, and dashed stroke rendering on a non-trivial composite path. - color_morph.svg combines animateTransform (rotate) with two parallel <animate> elements driving rx and ry on the same rect, so the screenshot grid proves multi-attribute animations on one element actually compose. All three are referenced from theme.css with cn1-svg-width / cn1-svg-height (mm) so the rendered size carries across DPI. The static screenshot test now also includes logo_text + wave_path; the animated grid adds color_morph alongside spinner + pulse. Initializr agent skill - New "SVG icons -- build-time transcoder" section in scripts/initializr/common/src/main/resources/skill/references/css.md documenting the recommended sizing keys (mm > source-dpi > implicit), feature coverage, and the seamless `Resources.getImage(name)` path. Pointed at the developer-guide chapter for full detail. Future agents recommending CN1 icons will steer users to SVG by default.
- New SVGClipPath model and parser path for <clipPath> (in <defs> or top-level). <mask> is treated as a clip alias -- alpha masking falls back to opaque, but the geometric clip outline still applies, which is the right answer for badge-style usage where the mask is just an alternate way of expressing a rounded outline. - StyleParser now reads clip-path="url(#id)" via the same url() parser that resolves gradient refs. SVGStyle gets a clipPathRef field; inherit() does NOT propagate it (matches SVG spec). - emitNode wraps the shape paint in pushClip / setClip(clipShape) / popClip when the resolved style has a clip ref. emitClipShape re-emits the first child shape of the clipPath as a fresh GeneralPath (rect / rounded-rect / circle / ellipse / polyline / polygon / path including arcs). Multi-shape clipPaths and nested clip-on-clip references are flattened to the first shape -- the common case for icons. Tests + fixtures - New CompileGeneratedSourceTest case (rect + circle clipPath against two filled rects) -- catches codegen regressions against the real CN1 Graphics surface. - clipped_badge.svg fixture exercises a rounded-rect clip masking a linear-gradient fill plus clipped text, all in one file. Added to theme.css and the static screenshot test so the iOS / Android / JavaSE screenshots prove the end-to-end clip path works.
CI's docs/developer-guide quality gate flagged five Vale errors: - Replace ASCII 'x' dimensions (1x1, 24x24, 1024x1024) with proper multiplication signs so proselint.Typography stops complaining. - Reword 'it is' to drop the Microsoft.Contractions violation. Doc content is otherwise unchanged.
Replaces the previous Class.forName / OpenHook wiring with the simpler arrangement: each platform's Stub registers transcoded SVGs with the global Resources image table BEFORE the user's init(Object) runs. Resources stays minimal -- it already exposes the static registerGeneratedImage(name, Image) method; getImage now prefers the generated registry over the local resources map so SVGs override the CSS-compiler placeholder PNGs that share the same name in theme.res. The transcode-svg mojo always emits SVGRegistry.installGlobal() now (even with zero SVGs it's a no-op), so callers can reference it unconditionally: * iOS -- IPhoneBuilder detects the generated SVGRegistry.class in the user's compile output and weaves its installGlobal() into the stub right before i.init(this) in the generated Stub.java. * Android -- AndroidGradleBuilder does the same in its generated Stub's run() before i.init(this). * JavaSE desktop -- the cn1app-archetype Stub template calls installGlobal() unconditionally; the codenameone-svg-transcoder always produces the class so the reference always compiles. (The hellocodenameone JavaSE Stub gets the same change manually.) * JavaSE simulator -- the Executor (which dynamically loads the user's main class) does a Class.forName + getMethod dance for the registry right before invoking init(), matching the existing reflection-heavy app-launching style of that class. This is per-port code, not framework code, so it doesn't cross the ParparVM reachability bar. The generated SVGRegistry shrinks to a single installGlobal() method (no static initializer, no install(Resources) variant) -- there is no hidden wiring anywhere; whoever wants the SVGs installed calls that method explicitly. Mirrored to BuildDaemon's IPhoneBuilder / AndroidGradleBuilder copies per the project's mirror requirement. The screenshot tests now read transcoded SVGs through the regular Resources.getGlobalResources().getImage(name) path; no glue code in test land either.
Expands the test surface to catch regressions in the less-trodden paths: - multiStopGradientCompiles -- 5-stop linear gradient (red -> yellow -> lime -> aqua -> blue). Confirms the codegen handles >2 gradient stops through the LinearGradientPaint constructor's fractions/colors arrays. - deeplyNestedGroupsCompile -- five-deep <g transform="..."> nesting. Catches local-variable shadowing regressions in the per-block __tsave / __tnew naming when many transform blocks stack. - skewTransformsCompile -- skewX and skewY composed with translate. Skew used to drop on the floor in emitApplyMatrix; covered now. - valuesAnimationCompiles -- two parallel <animate values="..."> on the same circle (r driving size, opacity driving fade). Covers the values-list flow distinct from the from/to two-keyframe shape. Path data: - smoothQuadraticReflectsControlPoint -- T after Q uses the reflection of the prior control point. - smoothCurveFallsBackToCurrentPoint -- S without a prior C uses the current point as its implicit first control (spec rule). - closeFollowedByImplicitMoveRebasesStart -- the current point after Z is the subpath start, so a relative m thereafter is relative to that start, not the close target. Dev guide: short note flagging that hellocodenameone publishes the SVG-rendered grid as a CI artifact and the source SVG fixtures live under scripts/hellocodenameone/common/src/main/css/. Resolves the "screenshot in dev guide" follow-up without committing a binary that would drift -- the reader can pull the latest from CI. 73 tests passing (up from 66, +7 from this commit).

PMD's LogicInversion rule complained about the negated-greater-than check in GeneratedSVGImage.mmToPixels. The original form deliberately caught NaN (since `NaN > 0` is false, `!(NaN > 0)` is true) but PMD can't see the intent. Spell it out explicitly with `mm <= 0f || Float.isNaN(mm)` so the NaN guard survives and the rule is happy.
Two regressions called out: 1. clipped_badge.svg never appeared in the static screenshot capture. Root cause: BoxLayout.y stacked the six SVG labels off the bottom of the iOS / Android viewport, so the screenshot framework only captured the first three. Switch the test form to GridLayout(3, 2) so every transcoded SVG fits in a single capture (star + gradient_circle row, path_arrow + logo_text row, wave_path + clipped_badge row). 2. logo_text.svg rendered as nothing on iOS Metal. The Graphics.drawStringBaseline path misrenders text under a non-identity transform on the Metal port (the entire SVG paint happens inside the viewport setTransform). Switch the codegen to plain Graphics.drawString and convert SVG's baseline y to drawString's top-left by subtracting Font.getAscent() (fall back to getHeight when ascent <= 0, which happens on a couple of font paths). drawString is the more widely-supported entry point on every CN1 port.
Text was painted with `Font.getDefaultFont().derive(size, weight)` which
throws on Android (default font is a bitmap system font, not TTF) and
that hung SVGStaticScreenshotTest for the entire instrumentation run.
Switch to `Font.createTrueTypeFont("native:MainRegular" / ...)` based on
the SVG `font-weight` / `font-style` and derive the requested pixel size
from the resulting TTF. Never use `createSystemFont`.
Text also needs to render in parent-transform space because iOS Metal
does not pick up the active Graphics transform for `drawString`. The
runtime now exposes `drawSvgText` on `GeneratedSVGImage`: it restores
the pre-SVG transform, scales the font by the SVG->screen factor, and
translates the SVG baseline coords to screen pixels.
Gradient fills had the same Metal problem -- `setClip(non-rect Shape) +
LinearGradientPaint.paint` rendered as a triangle for arc-decomposed
paths because Metal substitutes a degenerate polygon. The new
`fillSvgGradient` helper renders the gradient and a path-shaped alpha
mask to off-screen images at screen resolution, masks the gradient and
blits the result in parent-transform space, sidestepping the clip.
Generator updated to emit `drawSvgText(...)` / `fillSvgGradient(...)`
in place of the inline recipes, and to drop the now-unused
`LinearGradientPaint` / `MultipleGradientPaint` / `Font` imports.

The previous commit added drawSvgText / fillSvgGradient helpers that restored the parent transform to bypass two iOS Metal renderer bugs. That belongs in a Metal-focused PR, not here -- the transcoder should emit the straightforward CN1 graphics recipe and let the port fix the bugs at the rendering layer. Reverted those helpers and the inline emission they replaced. Kept the GeneratedSVGImage.svgTextFont helper: that one is not a Metal workaround. It loads a TrueType face via the native: scheme so we can derive arbitrary pixel sizes -- otherwise Android's bitmap default font makes Font.derive throw and hangs the screenshot suite mid-paint. Documented the two known Metal bugs (drawString under transform, setClip on non-rect Shape) in docs/developer-guide/SVG-Transcoder.asciidoc and in the SVGStaticScreenshotTest javadoc so the next reviewer knows the Metal goldens are intentionally capturing the broken behavior.

App code no longer calls SVGRegistry.install(theme) -- the per-platform Stub generated by the cn1 builder emits installGlobal() before init(Object) so the registry is wired automatically. Reflect that in the Quick Start, drop the manual call from the troubleshooting section, and update the limitations bullet that still described the install as "explicit".

Captured from CI run 26469559178 (Android) and 26469560225 (iOS) on commit f8e1b4e. SVGStaticScreenshotTest + SVGAnimatedScreenshotTest now have stable baselines for every port that runs the hellocodenameone device-runner suite. The goldens deliberately encode current per-port rendering bugs so the follow-up port-side PRs can replace each baseline with the corrected output: - iOS (legacy + Metal): setClip(non-rect GeneralPath) draws a triangle for gradient_circle.svg and clipped_badge.svg. - iOS (legacy + Metal): <animate> on fill color does not tick, so color_morph.svg's red diamonds vanish on legacy and freeze on Metal. - Android: gradient_circle.svg paints the fill plus an outline of the same circle stacked. Doc + test javadoc updated to accurately describe what each golden is recording. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Vale's Microsoft style guide flags contractions ("does not" -> "doesn't",
"did not" -> "didn't"), discouraged Latinisms ("e.g." -> "for example"),
and a couple of weak adverbs ("deliberately", "separately"). The
developer-guide quality gate treats these as build-breaking, so the
golden-bearing commit failed the docs build. Reworded the affected
sentences without changing meaning.

Two follow-ups on the SVG transcoder: 1. The transcode-svg mojo no longer emits a SVGRegistry class when the project has zero SVGs. The Stub-side injection in IPhoneBuilder / AndroidGradleBuilder already checked for the class file, so a project without SVGs now also has no registry reference in the generated Stub. A leftover SVGRegistry.java from a previous build (e.g. after an SVG is removed) is swept on the next run so the `.isFile()` check stays honest. 2. JavaSE-side, the registry now loads from JavaSEPort.init() via a reflective Class.forName + installGlobal() invocation, idempotent across multiple Display.init() calls. The cn1app archetype Stub template and the hellocodenameone JavaSE Stub no longer hard-code SVGRegistry.installGlobal() -- a project with no SVGs no longer pulls in a reference that wouldn't compile, and the same code path covers both the simulator and a desktop run. Dropped the older reflective load from Executor.java since JavaSEPort.init() runs in both code paths. Developer guide rewritten to lead with cn1-svg-width / cn1-svg-height millimeter sizing as the recommended path; dropped the public "Limitations and notes" section that exposed port-side rendering bugs to readers who shouldn't care about them. The current per-port rendering bugs the screenshot goldens encode now live only in SVGStaticScreenshotTest's javadoc so the next maintainer who refreshes the goldens still has the context. Resources / CSSTheme / SVGTranscoder javadoc references to the old `install(theme)` entry point updated. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

The Cn1ssDeviceRunner.shouldForceTimeoutInHtml5 path lists SVGStatic- ScreenshotTest and SVGAnimatedScreenshotTest in isJsSkippedScreenshotTest, but the "forced timeout (HTML5 fallback)" log marker never appears in JS CI output -- the path doesn't actually short-circuit on the JS port. Tests get run on JS anyway. SVGAnimatedScreenshotTest's chunk-emission hangs on JS under the 150s browser-lifetime budget (last successful run was at 81e4fef, then PR #5035 landed three new screenshot tests into the JS suite and pushed it past the budget). The PNG capture itself produces the same bytes / fingerprint as on iOS legacy, so this is a budget / harness flake, not a rendering regression. Opt out at the per-test level with an early return when getPlatformName returns "HTML5" so the JS suite stays under budget. The framework-level shouldForceTimeoutInHtml5 path can be debugged separately. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Fix iOS Metal and Android SVG rendering bugs exposed by PR #5042 Three rendering-layer bugs the SVGStaticScreenshotTest / SVGAnimatedScreenshotTest captured in their goldens, now fixed at the port level so the goldens can be retaken on top: 1. iOS Metal clip on arc-decomposed paths -- gradient_circle.svg and clipped_badge.svg rendered as triangles. setClip(GeneralPath)'s native side (setNativeClippingShapeMutableImpl and setNativeClippingPolygonGlobalImpl) ignores the path command stream and treats the raw points buffer as a flat polygon. For a path with QUADTO segments, every control point appears as a polygon vertex, and the stencil triangle-fan that CN1MetalApplyPolygonStencilClip uses produces the degenerate triangle. Fix at the Java boundary: flatten any non-rect ClipShape via midpoint subdivision into a polyline GeneralPath before sending it down, so only true polygon vertices reach the native side. Works for both the global and mutable-image paths. 2. iOS Metal drawString skips the affine scale -- CoreText shapes the line and the atlas rasterises glyphs at font.pointSize, so a quad stretched by a 2x-4x viewBox transform smears the bitmap on the GPU. CN1MetalDrawString now reads the effective screen scale from currentTransform (column magnitudes of the 2x2), rasterises the atlas at font.pointSize * scale via [font fontWithSize:...], and divides every glyph position / bearing / bbox / slot dimension by the same factor so the vertex coords stay in caller-side space. The vertex shader re-applies the same scale via the transform and the result is a 1:1 atlas sample. Pure rotation / translation keeps the fast useScaledFont == NO path. 3. Android (and iOS Metal once #1 unmasked it) gradient_circle.svg double-circle -- the gradient fill landed below the dark-blue stroke instead of inside it. LinearGradientPaint.paint(g, w, h) captured g.getTranslateX()/Y(), zeroed them out, and baked them into t2 via t2.translate(startX + tx, startY + ty). On every active port (isTranslationSupported() == false) Graphics.setTransform already conjugates the user matrix with T(xTranslate) so the cell offset applies at the screen level; baking tx/ty inside a translate that sits before the SVG scale meant the offset went through that scale twice (sy * label_Y extra) and slid the gradient fill off the circle. Drop the dance entirely -- build t2 as T * Translate(startX, startY) * Rotate * Translate(0, -ph/2) and let the existing conjugation re-apply the screen-level offset. Also drops the "Known port-side rendering bugs the goldens encode" block from SVGStaticScreenshotTest's javadoc -- those items are this PR. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Replace em-dash with ASCII in LinearGradientPaint comment CI's "Java sources must be ASCII-only" guardrail flagged the em-dash that slipped into the explanatory comment block. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Gate LanguageTool steps on the same paths filter as the HTML build "Run LanguageTool grammar check" reads build/developer-guide/html/developer-guide.html, which is produced by "Build Developer Guide HTML and PDF" -- already gated on docs/demos/workflow paths. The LanguageTool step lacked that gate, so on PRs that didn't touch any of those paths (i.e. most non-docs changes) the script crashed with FileNotFoundError and the final quality-gate step failed the build with status=1 / count=0. The same condition now gates "Set up Java 17 for LanguageTool", "Install language-tool-python" and the grammar check itself, so LANGUAGETOOL_STATUS stays unset and the quality gate's "${LANGUAGETOOL_STATUS:-0}" check defaults to 0. Surfaced on PR #5049 (iOS port + LinearGradientPaint fix) where none of docs/demos/workflow had been touched. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Refresh Android SVGStatic golden after LinearGradientPaint fix The LinearGradientPaint translate-conjugation fix changes gradient_circle.svg rendering from "two stacked circles" to a single filled+stroked circle. This is the new expected baseline; existing golden was captured with the bug. Default Android job ran on this PR with the fix and produced the SVGStatic.png captured here, which now matches the post-fix output and turns the JDK 17 / JDK 21 matrix runs (which set CN1SS_FAIL_ON_MISMATCH=1) green. No other Android goldens changed -- only gradient_circle was misrendered on Android, and the artifact upload's `artifacts/*.png` pattern only captures the screenshots flagged as different by cn1ss_process_and_report. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Forward clip-path through the presentation-attribute whitelist SVGParser.setShapeAttrs builds a `pres` map containing only the attribute names it explicitly lists, then hands that map to StyleParser.parse. `clip-path` wasn't in the list, so any inline `clip-path="url(#id)"` on a shape silently disappeared and the emitted code never wrapped the shape in `g.setClip(__clipN)`. Most visible on SVGStaticScreenshotTest's clipped_badge.svg, whose outer rect rendered as a plain square instead of the rounded badge. StyleParser already knows how to consume `clip-path` (sets SVGStyle.clipPathRef), and the code generator already wraps draws in push/setClip/pop when getClipPathRef() is non-null. The whitelist gap was the only thing keeping the value from reaching either of them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Guard currentTransformGlyphScale against NaN / non-positive scale The function reads `currentTransform.columns[i]` directly and feeds the resulting magnitude into `font.pointSize * s`. If any column entry is NaN (e.g. a degenerate transform sneaks in before CN1MetalSetTransform has run) the multiplication propagates the NaN into UIFont's pointSize, and the subsequent CTLineCreate / atlas-glyph lookup hangs the simulator -- the iOS Metal UI tests timed out at FillShape on the first run of #5049 with this exact symptom, and a retry passed. Add an `isfinite(s) && s > 0` check that returns 1.0 (the unscaled-font fast path) when the inputs aren't a finite positive scale. Cheap defensive guard against the same flake recurring. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Stop rejecting alpha-mask paths whose bounds sit at negative coords `Renderer_getOutputBounds` returns { minX, minY, maxX, maxY } in renderer pixel space, and three callers in the iOS port (`nativePathRendererCreateTexture` Metal + GL ES2 branches, `nativePathRendererToARGB`, and `DrawPath.execute`) early-returned when `maxX < 0 || maxY < 0`. That fires for any shape whose bounding box is entirely in the negative quadrant -- the SVG transcoder emits exactly that shape for `spinner_animated.svg`'s children (`<rect x="-5" y="-40" width="10" height="20" .../>`), so after the SVG scale-bake the renderer saw bounds in the (-7, -60) -- (8, -30) range. maxX = 8 was fine but maxY = -30 < 0 tripped the guard, the texture handle came back as 0, and `g.fillShape` silently dropped every rect: the spinner column was blank on the iOS Metal animated golden. `width = maxX - minX` and `height = maxY - minY` are the correct emptiness check -- a path with non-empty extent has positive width and height regardless of where the bounds sit on the axis. Drop the maxX/maxY < 0 guard and rely on the existing width / height == 0 check below. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Refresh iOS Metal SVG goldens after clip + spinner fixes Updates SVGStatic.png and SVGAnimatedScreenshotTest.png to the post-fix Metal output: - SVGStatic.png: gradient_circle no longer renders as a triangle (the setClip(GeneralPath) curve-flatten fix at the Metal port boundary converts the arc-decomposed circle into a real polygon before reaching the polygon stencil writer); the dark-blue stroke now wraps a properly filled gradient circle. - SVGAnimatedScreenshotTest.png: the spinner_animated column is no longer blank. The four rotating rounded rectangles are now rasterised through the alpha-mask pipeline (the nativePathRendererCreateTexture maxX/maxY < 0 guard was rejecting alpha masks for shapes positioned in the negative quadrant and the spinner rects all sit at y in [-40, -20], so every call short- circuited to a nil texture). Captured from the build-ios-metal job on the same commit set; clipped_badge.svg still shows a square baseline because the SVG transcoder's clip-path forwarding fix landed in a separate commit that needs the CI Maven cache to drop the prior svg-transcoder JAR before it takes effect. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Refresh iOS legacy SVG golden after LinearGradientPaint fix Same gradient_circle.svg fix applies to the GL backend: the filled circle no longer stacks below the dark-blue stroke (was the same LinearGradientPaint translate-conjugation bug, not Metal-specific). clipped_badge still renders as a square here too -- the rounded clip-path takes effect once the CI Maven cache rebuilds the svg-transcoder JAR. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Include svg-transcoder sources in cn1-built cache key The cn1-built cache stores ~/.m2/repository/com/codenameone -- the built CN1 + iOS port JARs that downstream test jobs reuse without re-running setup-workspace. Its key was hashed over the iOS port + codenameone-maven-plugin sources but not svg-transcoder. After the SVGParser clip-path forwarding fix landed on this branch, the cn1-built cache key was unchanged, the cache hit short-circuited setup-workspace, the test app generated against the previous-build svg-transcoder JAR, and clipped_badge.svg kept rendering as a square in the Metal screenshot (the screen tells us SVGParser's fix didn't reach the JAR the test app actually loads). Adding `maven/svg-transcoder/src/main` to the hashed source tree makes the cn1-built cache key shift whenever someone changes the transcoder, forcing a fresh build through setup-workspace. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Use build-port's published cache key in remaining iOS jobs scripts-ios.yml's build-ios job, ios-packaging.yml's packaging job, and scripts-ios-native.yml's native-ios job all restored the cn1-built cache by recomputing src_hash locally rather than reusing the job output that build-port already published. Whenever build-port's src_hash gets a new source path (most recently maven/svg-transcoder/src/main, to make a transcoder fix invalidate the cache), these consumer jobs would silently diverge -- a cache saved under one key, a restore demanded under another -- and the restore step hit fail-on-cache-miss before the test app could even build. scripts-ios.yml's build-ios-metal job already used the published key correctly; the other three were holdovers. Switch them to the same pattern so the next person adding to src_hash only has to touch _build-ios-port.yml.

Summary
Introduces a new
maven/svg-transcodermodule that parses SVG files at build time and emits Codename OneImagesubclasses rendering via theGraphicsshape API — no Batik, no Flamingo, justjavax.xmlStAX. SVGs dropped intosrc/main/svg/of any cn1app become Java classes that work on every platform CN1 supports.Highlights:
LinearGradientPaint, fill/stroke/stroke-width/linecap/linejoin/opacity.<animate>,<animateTransform>(translate/scale/rotate),<set>. Time values are interpolated against wall-clock time on every paint, withfrom/to/values/begin/dur/repeatCount/fill="freeze"honored.com.codename1.svg.GeneratedSVGImagebase class plus a small registry probe inResources.getImageso transcoded SVGs appear under their source filename (getImage("home.svg")orgetImage("home")) for anyResourcesopened in the VM.transcode-svgmojo bound togenerate-sources(no CSS-compiler changes required for v1).javax.tools.JavaCompilerto catch codegen regressions. Five SVG fixtures + two screenshot tests added underscripts/hellocodenameone(static shapes/gradient/path + two animated, withsetAnimationTimeMillispinning the frame for deterministic captures).Scope explicitly excluded for v1: text, masks/clip-paths, filters, radial-gradient paint (falls back to first stop color), CSS keyframe animations.
