CCSVG provides an API for loading, displaying and animating SVG images on iOS using Cocos2D.
// load an svg image
CCSVGSource *source;
source = [CCSVGSource sourceWithFile:@"player_idle.svg"];
// display an svg image
CCSVGSprite *sprite;
sprite = [CCSVGSprite spriteWithSource:source];
sprite.position = ccp(240,160);
// create an svg animation
CCSVGAnimation *animation;
animation = [CCSVGAnimation animationWithSourcesNamed:@"player_walk_%04d.svg"
count:2
delay:1.0/15.0];
// run the animation on the sprite
CCSVGAnimate *animate;
animate = [CCSVGAnimate actionWithSVGAnimation:animation];
[sprite runAction:[CCRepeatForever actionWithAction:animate]];
SVG images are displayed as vector data, not textures. Each file is tesselated and cached in a vertex buffer object, so the peformance penalty of tesselating and uploading the geometry to OpenGL only happens once when the file is first loaded.
- Resolution-independence.
- Smaller file size.
- Smaller memory footprint.
- Faster load times.
There is a significant performance penalty for using images with transparent fills or strokes (drawing them properly means turning on blending in OpenGL). Avoid them where possible.
- Incomplete SVG support (see what is implemented in MonkVG).
- Antialiasing requires multisampling to be enabled, which has a performance penalty.
