Mac Quartz PDFs that use ordinary transparency groups and device-space soft
masks now render complete pages, so the default strict Laravel page-image
route can serve them. Upgrade normally; requireComplete stays enabled.
Cached page images are refreshed automatically, including custom namespaces.

Added

  • Form transparency groups with isolated/non-isolated backdrops, knockout,
    native Gray/RGB/CMYK blending and invocation alpha/blend/mask applied once.
    Equivalent normal groups draw directly without an unnecessary buffer.
  • ExtGState Alpha and device-space Luminosity masks with BC backdrops,
    Identity, sampled, exponential and bounded stitching transfer functions.
    Mask coordinates are fixed when gs installs them. AIS shape semantics,
    explicit/soft image mask precedence and atomic path/glyph fill+stroke.
  • All sixteen PDF blend modes, including Hue, Saturation, Color and Luminosity.
    Page groups blend before the white display background is applied.
  • Cropped offscreen and soft-mask buffers count against the shared live
    maxRenderPixels cap and are checked against the memory budget and PHP's
    hard memory limit before allocation. Recursive masks share the form-depth
    guard. Calculator transfers, calibrated luminosity masks, unknown group
    spaces/modes and TK=false text remain reported approximations.

Validation

  • Own synthetic Quartz fixtures, Chromium goldens for every blend mode and
    alpha/luminosity masks, child-process memory checks and cache-upgrade coverage.
    Bounds remain MAE <=2 and <=1% pixels off by >64. Chromium's measured
    isolation/knockout limitation is explicit; those cases use independently
    expanded ISO equations and tests proven red when I or K is ignored.
  • A local, uncommitted six-page Quartz document renders complete at 1x and 2x.
    No third-party runtime dependency or fixture is added.

Changed

  • BREAKING for custom pixel caps: maxRenderPixels now counts all live
    rendering buffers, rather than only the page. If your cap was exactly one
    page's area, allow room for group/mask buffers or request a lower scale.
