Global Variable


An option for the color format to use for intermediate results when rendering with the context.


const CIContextOption kCIContextWorkingFormat;


The value for this key is an NSNumber object containing a CIFormat value. The default working format is kCIFormatRGBA8 for CPU rendering and kCIFormatRGBAf for GPU rendering. For greater color precision, GPU rendering also supports the kCIFormatRGBAh format, but this format requires twice as much memory and can be used only with color management enabled.
