Introduce Slot APIs for efficient slot data reuse
New APIs:
- uint32_t LottieAnimation::gen(const char* slots)
- Result LottieAnimation::apply(uint32_t id)
- Result LottieAnimation::del(uint32_t id)
Removed API:
- Result override(const char* slot)
- Use RenderPath common interfaces instead of
direct array manipulations.
- Replace multiple scalar operations with Point utility
operations where applicable.
- introduced a blending factor to control the mix between the original color and the tritone effect.
- improved Lottie compliance with this enhancement.
- implemented the spec by all engines
CAPI:
* Tvg_Result tvg_scene_push_effect_tritone(Tvg_Paint* scene, int shadow_r, int shadow_g, int shadow_b, int midtone_r, int midtone_g, int midtone_b, int highlight_r, int highlight_g, int highlight_b);
-> TVG_API Tvg_Result tvg_scene_push_effect_tritone(Tvg_Paint* scene, int shadow_r, int shadow_g, int shadow_b, int midtone_r, int midtone_g, int midtone_b, int highlight_r, int highlight_g, int highlight_b, int blend);
The "s" key does not have to appear at the beginning
of the position block. Previously, such cases would
result in a parsing error — now they are handled correctly.
The incorrect line join used for OffsetPath was caused
by changes to the StrokeJoin enum values in commit
34d731fa94. During those
changes, the line join value for OffsetPath was mistakenly
not updated.
effect(name) / effect(index)
effects finds the effect by its name in the Effect Controls panel.
The name can be the default name or a user-defined name.
If multiple effects have the same name,
the effect closest to the top of the Effect Controls panel is used.
example:
- effect("Fast Blur")("Blurriness")
issue: https://github.com/thorvg/thorvg/issues/3115
Duplicated text document properties (fill color, stroke color, and stroke width) to the text range.
If these properties are not defined in the range selector, ThorVG incorrectly overrides them with default values.
The correct behavior is to preserve the original values. The added flags address this issue.

ThorVG cap/join enums and lottie specs were not aligned.
Problem was observed for StrokeCap::Square and StrokeJoin::Bevel.
Note: this change breaks backward comatibility.
This function sets the value of a specified expression variable within a particular layer.
It is useful for dynamically changing the properties of a layer at runtime.
Experimental API
- Result LottieAnimation::assign(const char* layer, uint32_t ix, const char* variable, float value)
- Tvg_Result tvg_lottie_animation_assign(Tvg_Animation* animation, const char* layer, uint32_t ix, const char* var, float val)
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
Until now lottie loader supported only a single
dash-gap pair, and only the case where only the dash
was provided was handled correctly. When both values
were provided, the gap was incorrectly increased by
the dash value. If more values were supplied, only
the last pair was considered.
@Issue: https://github.com/thorvg/thorvg/issues/3191
Unify the common parts of the parsing logic
by applying a strategy pattern,
allowing the behavior to vary based on the effect type.
This helps to reduce the size and improved the parsing safety.
The text stroke's 'of' property determines whether
the stroke appears above (true) or below (false)
the fill.
Previously, it was incorrectly used to decide whether
the stroke would render.
@Issue: https://github.com/thorvg/thorvg/issues/3126
- Allow the masking data even though they were mask None mode.
Those will be used by the layer stroke effect.
- Fixed masking Offset to apply to all masking chains.
- Optimized fast track masking with resolving the opaicty condition.
- Clean up the overall code.
