I’ve uploaded a new revision of FotoPreProcessor. Now it is possible to navigate back and forth while in preview mode. And a flaw regarding CR2 files (Canon’s RAW file format) was fixed: when importing these raw image files using Qt’s routines the images are rotated automatically. Thus FotoPreProcessor must not apply the orientation information obtained from the file’s EXIF data. This is achieved by comparing the image’s size according to its EXIF data with the imported image’s size.
