We are processing 500 images tiff and jpg using this command
It should open all images, trim the image, flatten the image, resize to 1200px and then save in optimal jpg quality with a filesize lower than 500kb.

I thought I hadd it all working. Then I had to add -flatten to process the tiff files (otherwise 3 outputted files) and as a result the -trim stopped working on all images. Now the images are all OK, just not trimmed.

question: how can I force the trim command to work in this context?

Help appreciated

This seems to work but we don't know why repage is necessary here

"-trim" creates canvas dimensions and offsets for each image, that gives the location of the trimmed area on the original image. "-layers merge" uses canvas dimensions and offsets for the alignment of layers. "+repage" removes canvas dimensions and offsets, so they will be aligned by top-left corners.

See documentation http://www.imagemagick.org/script/comma ... php#repage etc.
