- Hue: Creates a result color with the luminance and saturation
of the base color and the hue of the blend color.
- Color: Creates a result color with the luminance of the base color
and the hue and saturation of the blend color. This preserves the gray
levels in the image and is useful for coloring monochrome images and
for tinting color images.
- Luminosity: reates a result color with the hue and saturation of the base color
and the luminance of the blend color. This mode creates the inverse effect of
Color mode.
- Saturation: Creates a result color with the luminance and hue of
the base color and the saturation of the blend color. Painting with this mode
in an area with no (0) saturation (gray) causes no change.
- HardMix: Adds the bottom & top. If the resulting sum for a channel is 255 or
greater, it receives a value of 255; if less than 255, a value of 0.

- Introduced RGB, RGBA, and HSL structures
- Migrated hsl2Rgb() from SVG loader to common module
This is a refactoring for upcoming hsl color functionlaities.
- Use RenderPath common interfaces instead of
direct array manipulations.
- Replace multiple scalar operations with Point utility
operations where applicable.
Previously, only single-level <use> references were supported.
If a <use> node pointed to another element that itself contained
a <use> node, the reference wasn’t resolved.
This has been fixed by replacing the array of postponed elements
with a list. The list is traversed, and nodes aren’t cloned while
they or any of their children remain unresolved. In such cases,
the target element also gets added to the list, enabling recursive
resolution of nested href references.

Clarify the FillRule usage by associating it
explicitly with color/gradient fills.
C++ API
* Result Shape::fill(FillRule r)
-> Result Shape::fillRule(FillRule r)
issue: https://github.com/thorvg/thorvg/issues/3116
The API allows now values <= 0 for dashes and gaps. Negative values
are treated as zero. The exception is when all provided values
are <= 0, in which case the dash is ignored.
This fixes the issue when dash = 0 was provided for strokes with round
or butt caps - the dot was not drawn, even though it should have been.
docs: the strokeDash API behavior's clarification for odd numbers
of values in dashPattern and refinement of the accepted values.
If stop is declared immediately after Gradient is closed, the stop is registered in latestGradient.
Change latestGradient to a Stack and add a stop only to the last added gradient.
When that gradient is closed, no more stops should be registered for that gradient.
And gradients do not allow nested declarations, so only the earliest declared Gradient is valid.
Clipping for the <use> node when a <symbol> was used,
was being overridden when 'overflowVisible' was 'true'
(the default value), which caused the 'clip-path' applied
to the <use> node to have no visible effect.
The clipping for the <use> node (without <symbol> node) was
transformed in an incorrect order, resulting in a visually
incorrect results.
@Issue: https://github.com/thorvg/thorvg/issues/3392
- modify the concept of AABB to apply only to transformed shapes.
- transform points before computing the bounding box min/max
to obtain a more compact shape region.
- trimmming memory by removing the cached matrix, about 36kb
of memory has been reduced per paint instance.
If the svg contained an unsupported element with <stop> elements,
they were incorrectly assigned to the last loaded gradient. Now fixed.
@Issue: https://github.com/thorvg/thorvg/issues/3321
Support the bindings to be more integrable with a system's coherent memory management.
Pleaes note that thorvg now only allow the desinated memory allocators here:
malloc -> tvg::malloc
calloc -> tvg::calloc
realloc -> tvg::realloc
free -> tvg::free
issue: https://github.com/thorvg/thorvg/issues/2652
If a clip was defined by a use node pointing
to a basic shape subject to transformation, and
the use node itself was translated, the order
of applying these transformations was incorrect.
ThorVG pImpl idiom caused internal data to be scattered
across hierarchical classes. This refactoring consolidates
the data by inheriting pImpl internally, reducing memory
allocation counts and eliminating unnecessary strategy methods.
certain systems, may not support file I/O operations.
ThorVG should provide users with an option to configure
builds according to their requirements.
This ensures that file I/O calls are avoided,
preventing potential crashes.
Please use the meson '-Dfile=true/false' option for this.
Please note that "THORVG_FILE_IO_SUPPORT" might be expected
for your thorvg manual build.

Remove the requirement for unique_ptr in the function prototypes.
This change will simplify the API usage, making it more streamlined
and user-friendly. However, memory management will now be the
responsibility of the user.
