CGBitmapContext的绘图选项

[英]Options to CGBitmapContext for Drawining

Is there an option to the CGBitmapContext or Quartz 2D? CGBitmapContext或Quartz 2D是否有选项? I want to use it for drawing on an UIImage in monotouch. 我想将其用于在monotouch中的UIImage上进行绘制。

thanks Alex. 谢谢亚历克斯。

Drawing is always performed on a CGContext . 绘制始终在CGContext上执行。 If you want to draw onto an existing image, CGBitmapContext is logically the context to use. 如果要绘制到现有图像上, CGBitmapContext逻辑CGBitmapContextCGBitmapContext是要使用的上下文。
