Hello Everyone,
I've got a few questions about NSBitmapImageRep, specifically the method
+representationOfImageRepsInArray:usingType:properties:. If you pass nil
for the properties argument, does that in effect use some set of default
values for the properties needed by the specified file type?
Additionally, when you obtain data using -TIFFRepresentation or
-TIFFRepresentationUsingCompression:factor:, is this equivalent to using
NSTIFFFileType in +representation...? Do you imagine that the
implementation of -TIFFRepresentation is built upon
-representationUsingType:properties:?
Finally, does +representation... Not work with NSBMPFileType? I searched
for this over at the macosx-dev archives and found some people with the same
issuse of NSBMPFileType causing +representation... To return nil, but never
did find an answer of solution to the question of whether this file type is
supported.
Thanks for your help!
Mike
