ImageMagick - Whole Directories

[Edd]

I've done a few searches and went on imagemagick's site but they haven't documented anything about applying commands to whole folders/multiple images. Surely, you can apply commands to a whole folder of images? I want to rotate about 100 images by 90 degress and I don't really want to do each individually. Anyone know how I can apply it to all images at once?

Thanks :)

Don't know for imagemagick but most viewers allow you to do that. You have digikam installed? Select the pics you want to edit, rightclick and choose rotate.

The most feature rich application I have found for this is XnView

It has a very ugly interface, but alas it is quite powerful

Yes, you can do it with a little bash script.

 

Assume that you have some ImageMagick command line, like, say, this:

convert X.png -shear 5 output/X.png

You can do this on a whole folder of things directly from the command line like this:

for FILE in *; do convert ${FILE} -shear 5 output/${FILE}; done

Try this: rotate

 

Then I think the code would be something like this:

mogrify -rotate 90 *.jpg
