Hi,
This is more a question than an issue, as you know JPEG is a destructive file format, re-saving is recompressing each time.
How can I ensure that the original data of the picture is not altered if I only want to modify exif values ?
Thanks
As far as I know, exiflibrary doesn't decompress and re-compress the image data. When editing exif vaues, the image data part of the image file is preserved unchanged.
