  1. pdGradient renderer and UC: initial build

    authored
    Tons of features and UI bits still to come, but as of this build, the
    basics are finally in place.  The new gradient editor supports
    adding/editing/removing an arbitrary number of nodes, all gradient
    settings are correctly serialized to/from XML strings, GDI+ gradient
    brushes can be successfully constructed from the results, and PD's brush
    control can already save/load gradient brushes just like solid and
    pattern brushes.
    
    I've tried to design the gradient editor to be extremely flexible, which
    will allow me to use gradients in multiple places throughout the project
    (e.g. a dedicated gradient paint tool vs a gradient map tool).  This
    will enable a range of neat features without the need for complicated
    custom gradient code, and thanks to the modular design of the pdGradient
    class, it shouldn't be too much work to someday implement gradient types
    unsupported by GDI+ (e.g. spiral).
    
    Next up is all the missing UI bits for modifying gradient nodes (color,
    opacity, etc), implementing angle and wrap and other parameters, and
    after that, "automatic" gradient creation a la Photoshop's "noise
    gradients" (https://helpx.adobe.com/photoshop/using/gradients.html).

  1. Move all text layer logic out of pdLayer and into pdTextRenderer

    authored
    This removes an enormous amount of redundant code, and greatly shrinks
    the pdLayer class (~700 LoC).  It also provides an excellent template
    for future layer types, where pdLayer only exposes two generic get/set
    functions for custom layer attributes, which are just wrappers around a
    separate, dedicated class (which has to manage all that custom data
    anyway).
    
    This should also slightly improve text layer rendering performance, as
    we do not need to reset text parameters between draws.  (All text data
    is now persistent inside pdTextRenderer.)

  1. Add non-modal prompts when converting text layer formats

    authored
    PD's internals now respect the differences between basic text layers and
    typography layers.  Instead of silently converting between basic text
    and typography rendering (which resulted in very confusing behavior,
    especially at image load-time), the relevant tool panels now explain to
    the user that they can non-destructively convert text layers to whatever
    format they desire.
    
    This approach doesn't interrupt work flow, and it prevents text layers
    from changing appearance every time the user switches tools.
    
    (Also: as clearly stated in the prompt, converting between layer types
    is completely non-destructive, and PD shares as many properties as it
    can between various text layer types.)

  1. Start work to differentiate text layer types

    authored
    Currently, text and typography layers are interchangeable from a coding
    standpoint.  I actually want to forcibly differentiate these layer
    definitions, to prep for tools like "Convert Text to Generic Vector
    Layer".  (Typography layers expose text as vector objects, while the
    text tool operates strictly in the raster domain due to the use of
    system text APIs.)
    
    This is also a required change before implementing a "WordArt" type tool
    (for handling more complicated text shape transformations, like
    text-to-path).
  2. Migrate the new pen and brush classes to use pdParamXML

    authored
    These were my test case for the new XML-based serializer, and so far, so
    good.
  3. New XML-based parameter class: pdParamXML

    authored
    Another nasty project I've put off for far too long is standardizing
    PD's internal parameter class (which tracks data passing between PD's
    central processor and individual processing functions, so we can record
    it for macros and the like) against PD's various file-specific
    functions, which have all been migrated to XML.  This has been a blocker
    for a bunch of tasks, including a built-in macro editor (for creating
    macros without needing to actually *record* them).
    
    I've now completed a pdParamXML class which is just about a drop-in
    replacement for the old pdParamString class.  This class fixes a lot of
    obnoxious interop issues, and it's also much better for
    backwards-compatibility between versions, as individual processing
    functions can track parameters by name instead of by ordinal (where
    parameter changes are impossible to auto-detect).
    
    The long-term goal is to remove all function-specific processing from
    PD's central processor, and have it just blindly pass strings to/from
    individual functions (instead of parsing out individual parameters, as
    it does now).  Besides macro editing, this is also is a required change
    before I can implement an official plugin module, but please note that
    it's going to take some time to get everything switched.
    
    Also, this will break macro backwards-compatibility for the 7.0 release.
    Sorry.

  1. New "pattern" custom dropdown control for the brush dialog

    authored
    All 53 GDI+ pattern styles are now exposed in a single, custom-built
    drop-down box.  To minimize localization efforts, hatches are listed by
    numeric ID and live preview, rather than text description.  (As an added
    bonus, I find this much more intuitive than say Paint.NET's similar
    dropdown, which just gives a tiny 16x16 preview of the brush and wastes
    the rest of the space on pointless text.)
    
    Because PD is awesome, all objects that support generic PD brushes
    (currently just text layers) automatically acquire this new support.

  1. New Pen (stroke) UC and dialog

    authored
    This is all very rough and there's a *ton* of clean-up left to do, but
    the core pieces are finally in place.  This was the last thing I needed
    before I could really clean out the Typography tool options window, so
    it's great to have it done!
  2. Brush and Color Selection UCs: highlight on Mouse_Over

    authored
    These controls were sorely missing some kind of visual feedback

  1. Initial build of fill user control + settings dialog

    authored
    WARNING: massive commit!
    
    PD 7.0 is going to provide a single master Fill class (brush in
    GDI/GDI+) and Stroke class (pen in GDI/GDI+) as the back-end for
    anything that can be filled and/or outlined, eg. text, shapes, arrows,
    whatever.  My goal is to make these classes support every fill/outline
    setting under the sun, and because the resulting settings are just
    stored as strings, all new tools will automatically support every
    fill/outline setting under the sun without any extra work on my part.
    
    This commit is the first step toward making that possible.  The
    Typography tool already exposed a lot of these features manually, but
    now, I've reworked the fill-specific settings into a single, standalone
    UC with a custom dialog and corresponding render class
    (pdGraphicsBrush).  From here on out, any feature added to the user
    control + rendering class will be automatically available to all other
    tools, which is great!
    
    There is still a *ton* to implement in the dialog, and textures in
    particular are going to be weird and messy, but this is an important
    first step.  Note that this commit *IS NOT BACKWARDS COMPATIBLE WITH
    TEXT IN EXISTING PDI FILES*.  PDI text layers will still save/load just
    fine, but any previous fill settings will be lost, as they are now
    stored in a totally different format.  I will likely be modifying this
    format further in the coming weeks, so as with any developer build,
    don't save PDI files you can't afford to lose (just in case).  Note that
    text background region fill settings are also lost; however, text
    backgrounds now support 100% of the features available when filling the
    text, so you now have way more options available for text backgrounds.
    
    The outline/pen UC is still TBD, but now that the bulk of the
    infrastructure for the Brush UC + rendering class is done (all that's
    left is feature implementation), I may turn to the outline/pen tool so I
    can call the Typography tool more or less done.  Then I can move onto
    implementing other on-canvas tools while still plugging away at
    fill/outline features.  We'll see.

  1. Typography tool: rework underline/strikeout to operate at line-level

    authored
    Not glyph-level.  With this change, an outlined underline/strikeout
    looks like one contiguous line, instead of a bunch of tiny glyph-width
    lines placed next to each other.  Trailing whitespace chars are also
    ignored when calculating underline/strikeout width and placement.

  1. Typography tool: improve robustness against GDI+ errors

    authored
    Some path transforms can fail unpredictably; if this happens, the
    typography tool will now try to be smarter about restoring an unmodified
    version of the glyph (as a "better than nothing" last resort).

  1. Get underline and strikeout working with the custom font renderer

    authored
    The font's specified positioning and sizing is used in both cases,
    woohoo!
    
    (I'll probably end up moving the actual rendering to a different
    position in the text engine so that outlining doesn't show the lines
    between characters, and trailing spaces are ignored, but that's easily
    done now that I've cracked how to pull the relevant information out of
    WAPI.)

  1. Add GetOutlineTextMetrics() support, so I can fix underline/strikeout…

    authored
    … behavior
    
    GetOutlineTextMetrics is a neat WAPI function that provides a ton of
    useful data, but man, struct alignment for the return is a disaster, and
    MSDN isn't helpful because VB silently performs its own word alignment,
    negating the need for some of the dummy padding bytes.
    
    I think I've sorted everything out, since I'm getting proper returns on
    the underline and strikeout entries on both XP and Win 8.  Fingers
    crossed that more testing bears this out.
  2. Allow disabling of live script previews via Interface Performance pro…

    authored
    …perties
    
    Always good to have a failsafe with performance-sensitive features.
  3. Restore language-specific previews in the font dropdown

    authored
    Language-specific font properties are no longer cached at program
    startup (because it was killing performance; see
    fcfeb0f).
    Instead, the round-robin cache used by the font dropdown UC caches those
    properties on-demand.
    
    Testing on a 2001-era PC shows no trouble with this approach, so I'm
    content to make it permanent.

  1. Typography tool: finish last character-level features

    authored
    (Well, maybe not the *absolute last* as I still need to fix underline
    and strikethrough... sigh)
    
    Anyway, after this commit, it's time to shift gears and start working on
    dedicated UCs for pen and brush selection.  This will not only let me
    clean up the Typography tool's various "visual" panels, but will also
    save me a ton of work on eventual Shape tools (which make use of the
    same fill and stroke features).
  2. Typography tool: implement orientation, jitter, mirror, inflation

    authored
    Lots of fun per-character options

  1. Start migrating various API bits into a new pdSystemInfo class

    authored
    This will be an ongoing WIP, seeing as there are so many random
    system-interaction bits throughout the project, but moving one of the
    bigger modules into a class is a good start.
  2. pdRandomize: new class for improved random number generation

    authored
    Fixes #162.
    
    Everything in the original issue report has been handled, save the
    creation of a matching UC.  That's outside the scope of what I need
    right now, but I'll revisit if/when it becomes relevant.

  1. Implement non-destructive layer shearing

    authored
    Yep, PD's that awesome.  ;)
    
    To keep the on-canvas UI simple, shear can only be controlled from the
    move/size tool panel.  I've seen other software try to cram shear
    controls onto the canvas (e.g. Inkscape) but this gets unruly pretty
    quickly.
    
    Also, I've temporarily suspended on-canvas arc prediction if shearing is
    active, because I haven't solved the math necessary to draw a sheared
    arc without it warping to strange new locations.
  2. Add non-destructive x/y shear properties to pdLayer

    authored
    I can't promise that these will actually work, but since I've gone to
    the trouble of implementing matrix-based affine transforms, it should
    theoretically be trivial to add non-destructive shearing too.
    
    If my theory proves incorrect, this commit "causes no harm" so it won't
    need to be rolled back (and perhaps I can revisit in the future).
  3. Improve rasterize prompt logic

    authored
    If the user initiates a merge operation on an image with text/vector
    layers, rasterization prompts will now be displayed ONLY if a
    text/vector layer is actually involved in the current merge operation.
    
    Said another way, merging 2+ raster layers will never raise a
    rasterization prompt.
  4. Implement non-destructive rectangular crops

    authored
    Cropping to a rectangular selection can be handled instantaneously by
    simply adjusting layer offsets and canvas size.  This effectively makes
    it a non-destructive operation, as no image data is lost - but even
    better, it avoids the need for rasterizing text and vector layers!

  1. Fix rotated layers to work with Image menu transforms

    authored
    Resize, rotate, etc now process rotated layers correctly.
    
    Since I was here, I also optimized various functions related to these
    transforms to cut down on memory churn.  Overall performance should be
    much better, especially on systems where RAM is tight.
Something went wrong with that request. Please try again.
