Previously, a picture with a half-translucent mask would not function correctly.
This fix addresses the bug by applying the expected composition step.
Note: Even after applying this patch, a half-translucent mask with shape fill alpha will still not work properly.
We should consider removing the fill alpha property, as it duplicates the Paint opacity.
@Issue: https://github.com/thorvg/thorvg/issues/1423
Migrate the id property to the base class internals
so that pimpl classes could access the data easier.
This is a sort of prerequisite change for the coming texmap anti-aliasing.
Previously, translucent png images are not displayed properly
due to alpha channels premultiplication.
This patch implements that missing part to support it properly
by introducing the Surface data between canvas engine & rasterizer

This identifier is useful when user identify the instance type in runtime.
ThorVG basically don't prefer to dynamic_cast() nor typeid(),
it compiles with -fno-rtti option for the optimial size.
Here is an example for the simple usage.
if (paint->identifier() == Shape::identifier())
auto shape = static_cast<Shape*>(paint);
@Issue: https://github.com/Samsung/thorvg/issues/693
Current paint::bounds() returns the coordinates under the raw status,
the values are not quite useful if the paint object has the transformed children.
Thus, we extends the feature and give an additional parameter "transformed"
to return the coordinates values after transformation by user demands.
This is also necessary for tvg format, since we need the exact view size of the scene information.
The previous api is deprecated and we introduce a new api to replace it.
@APIs:
+ Result Paint::bounds(float* x, float* y, float* w, float* h, bool transformed) const noexcept;
- Result Paint::bounds(float* x, float* y, float* w, float* h) const noexcept;
@Issues: https://github.com/Samsung/thorvg/issues/746
Pixel-based image picture doesn't work at size() method.
Obvisouly, we missed to implement it properly.
This patch corrects it.
@Issue: https://github.com/Samsung/thorvg/issues/656
The PaintType enum was used to set the paint type in the internal Paint
implementation. This solution is switched to an identifier with id() getter,
so that the information about the type can be reached from outside the Paint.
This patch introduces tvg loader module for loading .tvg binary files.
This allows to load and reuse pregenerated scene.
tvg file format:
.tvg is a binary file format designed for saving/restoring the scene content.
It allows to save scenes and reuse them in other apps or to restore state of
the application.
@Example:
auto picture = tvg::Picture::gen();
picture->load(EXAMPLE_DIR"/tvg_file.tvg");
canvas->push(move(picture));
@API Additions:
Result paint(std::unique_ptr<Paint> paint) noexcept;
@Issue: Issue ticket is #375.
Scene could avoid composition if its children is only child (non scene)
This patch bring it conditionally check so as to avoid unnecesary expensive job.
@Issues: 254
Splited out ClipPath routine from other pixel compositions'
since yet it's unlikely compatible...
Also revise internal engine interfaces to be simpler.
This is a step forward to enhance masking feature.
* common Picture : Introduce Picture's size setter, getter APIs
If picture or file loaded by picture has an explicit Size(width, height),
it is transformed to fit the size.
Add RawLoader class that loads and display raw images,
and adds a Rasterizer for image data.
Image data can be loaded via picture.
Loaded image supports Composition, Transformation and Alpha blending.
New API
Result load(uint32_t* data, uint32_t width, uint32_t height, bool isCopy) noexcept;
Changes:
1. New shape->duplicate(Shape) api.
2. New example: testDuplicate
3. Added capi binding for duploicate api
4. Added capi duplication test in testCapi.c
Description:
Added implementation of duplicate api. For now it supports stroke
properties and shape properties (fill color, path) duplication.
TODO:
Implement gradient properties duplication
remove unnecessary condition.
implementation won't be included multiple times not like headers.
Thus this condition is unnecessary.

picture now affords the memory data as input source so that
user can pass svg data memory directly.
