What command argument did you use. Output format? Did you +repage after the crop? If you missed the actual image with the crop the result will be nothing. Further processing after a crop without re-paging could also make images dissapear. Without knowing what you actually did it is difficult to tell ...

The script is a personal one, not appropriate for public consumption. However once I get $rot (and extract comments from images) I use... echo >&2 "Generating Smaller Image..." convert "$f" $rot -thumbnail ${nsize}x${nsize} -quality $nqual "$n" where $f is the origina and $n is the new 'web' image ...

No I mean before JPEG and PNG came about lots of programs, including photoshop and coreldraw added junk to the image format for their own purposes which were not (and probably will never be) understood by other programs. It has had every sort of compression and internal formating just tacked on, and ...

- Replies: 4
- Views: 27002
The problem appears to be that -normalize is a grey scale operator whcih works on each channel seperatally. It isn't really designed for handling RGB images as such. Such an operation for RGB is usally designed to not only expand the three color channels together, but also use a 'threshold' level of ...
