overlay text overlaps itself
raw viewer - exif info
unlikely to be fixable
Exif of the RAW files are not shown by EOG since it currently used libexif.
Furthermore, when the statusbar is enabled, the dimensions of the RAW image being displayed is also incorrect - it will show the dimensions of the preview image presented to EOG via the pixbuf as generated by the our loader. For images that are scaled, a small text box is generated and overlayed onto the bottom left of the image to provide original dimensions as well as minimal exif info
EOM and DNG
Using EOM, scrolling through images that include a.jpg, b.nef, c.dng, d.jpg is fine. If we set rating on the DNG and move to next image (it hsould be d.jpg) we are jumped to a.jpg and c.dng is not available anymore.
This behaviour is not seen with the other file types.
pixbuf: DNGs with mismatched jpeg subsampling
This can occur if the embedded preview is a TIFF wrapping a jpeg - this is an error from within libtiff and not a pixbuf loader since it has correctly identified the raw file , extracted the preview image and then tried to give this tiff to the tiff pixbuf loader
I have observed this with DNGs that have had their preview images updated via exiftool, with jpegs produced via rawtherapee. However similar DNGs processed by rawtherapee seem to generate jpegs with 2:1 and 2:2 subsampling that when embedded cause the problem seen above
