How can I access / retrieve / export the image data within a CIImage?
I'd like a copy of a CIImage image in a pixmap-style buffer in RGBA
format.
The CIImage -
imageWithBitmapData:bytesPerRow:size:format:colorSpace: and -
imageWithContentsOfURL: methods work fine for ingestion, but I
don't see how to access or export the bitmap once it's ingested
into the CIImage object.
There isn't any image data in a CIImage, it's a list of operations to
be performed when drawing. In order to get image data you have to
render it. In this case a CG bitmap context would probably be what
you want.
