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
@Issue: https://github.com/Samsung/thorvg/issues/655
This reverts commit cd5116b053.
Ah this breaks the Stress example due to Picture::duplicate() is not available...
Need to consider and come back again.
* common: added colorSpace() function
This patch introduces colorSpace() function for SW and GL engine.
* infra: change LoadModule:read() into LoadModule:read(uint32_t colorspace)
This patch changes LoadModule:read() into LoadModule:read(uint32_t colorspace)
* picture: implement passing colorspace into loader
This patch implements passing colorspace into loaders.
Loader->read is now called on the first update.
* external_jpg_loader: support colorspaces
* external_png_loader: support colorspaces
Bitmap based pictures doesn't need the viewbox,
LoaderModule should delegate the viewbox to the derived classes which
having vector-based image loaders such as svg, tvg.
In that case, paint resizing can be performed by the loaders by own
policy.
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;
