Mart1n Posted September 19, 2017 Share Posted September 19, 2017 I am wondering hos feasible it would be for paint.net to retain ALL the exif data that is to be found on the input file before editing At present the exif item "USER COMMENT" is populated by my panorama stitching software to hold field of view and vertical offset information to be used when the jpg file is converted to html for publication. This field is written back by paint.net but in a format not usable for this purpose Also, the section of the exif data known as XMP data (application specific exif addons) is appended to images by several apps including my stitching app to include the full dimensions and projection type and cropping data and this is used by social media repositories such as Facebook to decide how to display images. This data is completely deleted by paint.net updates Is this problem one that can easily be addressed in paint.net with an option to retain all exif/xmp data Martin Quote Link to comment Share on other sites More sharing options...

Paint.NET does not have any control over what it does with metadata when an image is loaded or saved.

Rick Brewster Posted September 19, 2017 Share Posted September 19, 2017 Well, I'll file a bug to track this anyway. Who knows, it may end up being easy to fix at some point.

Mart1n Posted September 19, 2017 Author Share Posted September 19, 2017 I thought it ought to be possible even with the caviat that it is not under direct control (see my the original reply above) because I understood that Photoshop and GIMP already had this facility - although I could not say whether it extends to app specific XMP data Martin Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted September 20, 2017 Share Posted September 20, 2017 I'm certain it's possible in principle, there's no denying that. The question is whether GDI+ or WIC provides access to this information at all.
