2004.06.29 04:44 "[Tiff] Saving Exif with TiffLib", by Alex Kon
My task is to save Exif-data into tiff-images. According to Exif specification I should put Exif-specific data into subIFDs, that are not linked into common directories chain. And, as far as I understand, there is no regular mechanism to create such IFDs, because SUBIFD tag, specified by TiffLib has its own hardcoded value, while Exif-tags with offsets to corresponding Exif-SubIFDs should have other values, that are defined by Exif-standart. Should I modify TIffLib (add Exif-tags and made some extension of SubIFD-mechanism) to solve my problems, or there is any other way?
