c3772d11af gl_engine: ignore masking alpha when calculate inv luma masking 2024-10-19 14:04:43 +09:00

dfd7693158 lottie: offset does not depend on shape direction 
According to tests in AE, the offset direction should
not depend on the direction of the shape. A positive
offset value expands the shape, while a negative value
contracts it. Fixed.

9109656800 sw_engine: fix _rasterDirectImage 
Since the source buffer is 32 bits, not 8 bits,
both alpha and inverse alpha need to be calculated.

d9bbd433e8 lottie: correct the array reserved size 
The color input will contain at least colorStops.count * 4
elements (not including alpha). Since the alpha offset values
don't have to much colorStops, estimation is used.

78285e1cfd lottie: fix offset 
For long Bezier curves compared to the offset value,
the offsetting algorithm caused deformation. The problem
became evident after adding mask extension, as the simple
shapes defined there are based on Bezier curves rather
than as shapes like a circle/rect/etc, which is the case
for the offset. Now fixed.

0a16152d75 api: renamed the composite with mask.

API Modification:

 - CompositeMethod Paint::mask(const Paint** target) const -> MaskMethod Paint::mask(const Paint** target) const

3c74e90b76 sw_engine: ignore small cubics 
During the stroke's outline calculation, the function
handling small cubics set all angles to zero. When
the cubic was small but not zero, this resulted in
incorrect outlines. Now such curves are ignored.
