I noticed a program on aminet that uses docdatatypes to save text
files and I got the following information from the author of the
datatypes, what you do is have files(sample pictures in your case)
and you open them via datatypes.library and just change their
attributes(such as Bitmap and colour tables etc), then do the save
method with tha raw tag. But most new picture datatypes do not
support saving(apart from the old ones), I have asked the author of
the warp datatypes to add this feature but he said there is no point
yet since for example setting a compression setting is not possible.
