Stefan_l_01 0 Report post Posted July 25, 2018 Hi There is an issue saving custom tiff tags: "double" array changes to "undefined" (see "orig" tag attach to "saved"). Note: Double Arrays are saved with field_passcount = TRUE, first param before data is fieldcount! (e.g. libtiff: TIFFSetField(PTiff, MY_CUSTOM_DATA, 5, Data)) I can not say whether it happens also for a single double or other Array data types. I added a tiff with custom tags so you can try out. Best regards Stefan test.zip Quote Share this post Link to post Share on other sites

Especially since you're using custom tags. Do you really, really, really need to use TIF? Quote Share this post Link to post Share on other sites
Stefan_l_01 0 Report post Posted July 27, 2018 Of course I need tif. It would be ok ( for me at least) to ignore the custom tags when saving (save without them), but saving them WRONG what gives me errors trying to load the tif is an issue. Quote Share this post Link to post Share on other sites
