Known bugs
|
|
----------
|
|
|
|
- outofmemory in arrays silently ignored
|
|
- blending doesn't use premultiplied colors (not porter-duff model)
|
|
- gradient color ramp is not interpolated in linear space
|
|
- linear and non-linear image formats behave both linearly
|
|
- radial gradient circle has got a fixed step instead of
|
|
proportional to its radius
|
|
|
|
-------------------------
|
|
Incomplete functionality:
|
|
-------------------------
|
|
|
|
- non-zero fill mode
|
|
- proper porter-duff blending
|
|
- masking
|
|
- scissoring
|
|
- child images
|
|
- VG_DRAW_IMAGE_STENCIL
|
|
- _PRE and BW_1 image formats
|
|
- VGU warp matrices
|
|
- EGL (image drawing targets)
|
|
- boundbox / point-on-path / tangent-on-path queries
|
|
- RENDERING_QUALITY_FASTER == RENDERING_QUALITY_BETTER
|
|
|
|
---------------------------
|
|
Possible portability issues
|
|
---------------------------
|
|
|
|
- GL_UNSIGNED_INT_8_8_8_8 and other for images
|
|
- GL_MIRRORED_REPEAT for gradients
|
|
- GL_CLAMP_TO_EDGE for gradients and pattern paints
|
|
- GL_CLAMP_TO_BORDER for pattern paints
|
|
- multitexturing for VG_DRAW_IMAGE_MULTIPLY, VG_DRAW_IMAGE_STENCIL
|

Bonus:

|
|
|
|
- gradient shaders? antialiasing shader?
