issue tiff saving and custom tags (double arr)

Recommended Posts

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

TIF support in paint.net is minimal and provided on a "Gee if it works - that's great" basis ( http://forums.getpaint.net/index.php?/topic/19468-lab-color-space/page__view__findpost__p__330287)

 

This means that there is unlikely to be a change in the way PDN handles TIF images. Especially since you're using custom tags.

 

Do you really, really, really need to use TIF?

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.

BTW this probably works a lot better in the latest version (currently 4.2.7). I've put in a whole bunch of metadata related work into the 4.2 series of updates.
