Hi, I'm working on a parser that needs to be able to extract graphics from PDF files. So far, I'm making good headway with the CGPDFxxx functions.
I have a question about extracting embedded bitmap images. When I encounter an XObject stream with subType /Image, I get a bunch of parameters that looks pretty close to the parameters to CGImageCreate. However, the 'Filter' parameter indicates /FlateDecode so I'm assuming that I can't just wrap the stream in a CFDataRef and then in a CFDataProvider - I'll need to actually decompress this data first using (according to PDF spec) zlib/deflate. Am I right? Anyone got any sample code or hints regarding how to go about this? --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
