these experimental apis are allowed to use
when the lottie loader is enabled.
APIs:
- Tvg_Animation* tvg_lottie_animation_new()
- Tvg_Result tvg_lottie_animation_override(Tvg_Animation* animation, const char* slot)
ThorVG has offered an option to clear the buffer since version 1.0.
This is essential when users utilize the canvas target buffer
with the main render target. They share the buffer
and need to draw contents onto the existing contents.
API:
Result Canvas::clear(bool free = true)
-> Result Canvas::clear(bool paints = true, bool buffer = true)
Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool free);
-> Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool paints, bool buffer);

This change introduces the CanvasEngine::All type to automatically
initialize the engines available on the current system.
These revisions improve the usability of these APIs.
Addtions:
- enum class CanvasEngine::All
Modifications:
- Result Initializer::init(CanvasEngine engine, uint32_t threads) ->
Result Initializer::init(uint32_t threads, CanvasEngine engine = tvg::CanvasEngine::All)
replace the frame count unit from the int32_t to float
since animations could smoothly interpolate key-frames.
This notificably improve the animation smoothness in Lottie
Beta API changes:
Result Animation::frame(uint32_t no) -> Result Animation::frame(float no)
uint32_t Animation::curFrame() const -> float Animation::curFrame() const
uint32_t Animation::totalFrame() const -> float Animation::totalFrame() const
These new apis would enable users to easily modify the motion scene,
The data structure of the paints has been changed from an array to a list.
@APIs:
std::list<Paint*>& Canvas::paints() noexcept;
std::list<Paint*>& Scene::paints() noexcept;
@Deprecated:
Result Canvas::reserve(uint32_t size) noexcept;
Result Scene::reserve(uint32_t size) noexcept;
@Issue: https://github.com/thorvg/thorvg/issues/1203
The tvg_gradient_get_identifier and tvg_paint_get_identifier
apis have been introduced. They set the newly introduced
Tvg_Identifier enum, which indicates the paint and gradient
types, respectively.
The previous meson script was incomplete,
therefore this change requires it to be revised.
To enable static linking use the next meson option.
"-Ddefault_library=static"

Non-changeable apis should keep the const parameter so that
user knows the api won't change the internal data.
Thanksfully, we didn't release the capis, we can change it.
The next api of c++ version has been deprecated
Tvg_Result tvg_paint_get_bounds(const Tvg_Paint* paint, float* x, float* y, float* w, float* h);
instead, we introduce the next one under the beta.
Tvg_Result tvg_paint_get_bounds(const Tvg_Paint* paint, float* x, float* y, float* w, float* h, bool transformed);
Changes:
- Removed beta api tag from CAPI module
- For some APIs, the tag has not been changed due to main API status
- Moved some documentation changes to have similar descriptions in main
API and CAPI
- Removed deprecation warnings.
Paints must clear canvas engine data if they were dismissed from the canvas,
1. Canvas::clear(free = false) must retain all the paints from the paints hierarchy
so that user keeps the all dangled paints lifecycle.
In this scenario, it could leak the engine data of paints, this patch fixes it.
2. Previously, t just keeps the immediate paints lives of canvas, but not them of children of scene nor picture.
This patch changes a policy which was not considered seriously,
Now it keeps the all paints lives through the tree-hieararchy.
3. Also changed the Scene::clear() behavior identical to Canvas::clear() for consistency.
@API Modification:
From: Result Scene::clear() noexcept;
To: Result Scene::clear(bool free = true) noexcept;
TVG_RESULT_INVALID_ARGUMENT returned in case a nullptr passed as an argument
(does not apply to color getters).
The change is addressed in the docs file.
