iphone Programming Glossary: cgcontextgetclipboundingboxDrawing in CATiledLayer with CoreGraphics CGContextDrawImage http://stackoverflow.com/questions/4067512/drawing-in-catiledlayer-with-coregraphics-cgcontextdrawimage It looks like this void drawLayer CALayer layer inContext CGContextRef context CGContextSaveGState context CGRect rect CGContextGetClipBoundingBox context CGFloat scale CGContextGetCTM context .a CGContextConcatCTM context CGAffineTransformMakeTranslation 0.f rect.size.height.. of head scratching and NSLogging showed me that within drawLayer inContext the size and offset of rect returned from CGContextGetClipBoundingBox context is exactly what you want to draw in. Where drawRect gives you the whole bounds. Knowing this you can remove the.. the context. Here's what I've ended up with void drawLayer CALayer layer inContext CGContextRef ctx CGRect rect CGContextGetClipBoundingBox ctx CGFloat scale CGContextGetCTM ctx .a CATiledLayer tiledLayer CATiledLayer self layer CGSize tileSize tiledLayer.tileSize..
