|
|
|
- Path rendering (move, line, quad, curve, arc)
|
|
- Images, flip v/h, aspect, alpha (PNG, JPG, GIF)
|
|
- Linear gradients (in all four directions)
|
|
- Transparency, fill and stroke
|
|
- Rotation, flip v/h
|
|
- Font rendering
|
|
- Dash patterns
|
|
- Clipping by path (not just rectangle)
|
|
- Alpha gradients (for glass effect)
|
|
- Encode result as image (PNG, JPG)
