Take a look at the iupgtk_image.c. The necessary conversions can be copied from there.
iupdrvImageCreateImageRaw() and iupdrvImageGetRawData() are opposite functions I doubt that you will be able to reuse code. iupdrvImageCreateImageRaw and iupdrvImageCreateImage also get the data from different sources, so the code will be similar but the data access will be different.
