Changing the orientation of an image

Post by dmor »

I would like to generate a series of test images for my application which have different orientations. I've tried using CONVERT & MOGRIFY to change the orientation, using the -ORIENT option. This doesn't seem to have any effect on the output file. I don't want to rotate the image, just store the data relative to a different origin. I've tried TIF, JPG, GIF etc. Am I misunderstanding the use of the -ORIENT option?

Thanks

Dave
