Options
These globals are now defined:
double duration; // The requested duration of the animation. double frame; // A value in [0, 1] of where we are in the animation.
This global is now defined:
GrBackendRenderTarget backEndRenderTarget;
GrBackendTexture backEndTextureRenderTarget;
Optional source image
These globals are now defined:
SkBitmap source; sk_sp<SkImage> image; GrBackendTexture backEndTexture; // GPU Only.
Note:
Adding comments with SK_FOLD_START and SK_FOLD_END creates foldable code
blocks.
These blocks will be folded by default and are useful for highlighting specific lines of code.
You can also use the keyboard shortcuts Ctrl+S and Ctrl+E in the code editor to set them.
