0.0.5 - 2026-01-08

This release has an MSRV of 1.88.

Added

  • The RenderContext now has a set_blend_mode (and a corresponding blend_mode getter method) that can be used to support non-isolated blending. (#1159 by @LaurenzV)
  • The RenderContext now contains a push_clip_path and pop_clip_path method for performing non-isolated clipping. (#1203 by @LaurenzV)
  • Experimental support for image filter effects: (#1286 by @grebmeg)
    • New filter API methods on RenderContext:
      • set_filter_effect() - Set a filter to be applied to subsequent drawing operations.
      • push_filter_layer() - Create a new layer with a filter effect.
    • FilterEffect trait providing both u8 and f32 precision variants for rendering across different backends.
    • Gaussian Blur filter with configurable standard deviation and edge modes (None, Mirror, Wrap, Duplicate). Uses an optimized decimated blur algorithm with automatic downsampling for performance.
    • Drop Shadow filter with customizable offset, blur radius, and shadow color.
    • Flood filter for solid color fills.
  • Added a set_mask method to make it possible to mask rendered paths without inducing layer isolation. (#1237 by @LaurenzV)
  • Added support for conditionally disabling the u8 or f32 pipeline. (#1294 by @nicoburns)
  • Improve performance of rendering opaque images. (#1327 by @grebmeg)

Known Limitations

  • Filter effects currently support only single-primitive filters; filter graphs with multiple chained primitives are not yet supported.
  • Multithreaded rendering is not supported for filter effects; filters are only applied in single-threaded mode.
