I see. I can try to compile some easy understandable sample code for you to explain how to write and read those tags using LibTiff.
But I have to take a closer look at the tags myself first. Maybe after Easter. I cannot say anything about their "interpretation" (i.e. meaning). Von: David C. Partridge [mailto:[email protected]] Gesendet: Donnerstag, 6. April 2023 21:36 An: [email protected] Cc: 'Sulau' <[email protected]> Betreff: RE: [Tiff] TIFF/EP A302 is an EXIF tag with the same name as 828E (CFAPattern). I know all three are defined in the source code (grep for CFA). My concern is sample code to guide me to interpret them correctly.

However, there are some issues at this stage. I was preparing an improvement at the time. I could update it and then upload it to my repository. From there you could get it and try it. Would that help? CFARepeatPatternDim (828D) and CFAPattern (828E) are define, but what is the tag-definition of A302? Regards, Su Von: Tiff [mailto:[email protected]] Im Auftrag von David C. Partridge Gesendet: Donnerstag, 6. April 2023 14:39 An: [email protected] <mailto:[email protected]> Betreff: [Tiff] TIFF/EP Is there any support in 4.5.0 for TIFF/EP? Does anyone know of any sample code that reads/processes/writes (e.g.) CFARepeatPatternDim (828E) and CFAPattern (828E or possible A302). Thanks David
