Hi

The following:

			convert \
				-crop +0+100 \
				-bordercolor silver \
				-border 10 \
				in.jpg \
				out.jpg

seems to do the border before the crop so the top border is cropped out of existence.

I've tried reordering the options but I can't simply get the image cropped then add the border to what's left.

I've tried using chop, too and I seem to end up with just the border!

Short of piping one convert with a crop into another convert with the border, I'm running short if ideas. What should I be doing? Thanks.

Why do you expect IM to understand that you want things done in a particular order, when you don't tell IM the right order to do thing in.

You can't crop and add borders to an image that you have not read.
In fact IM probably should throw an error (or at least a warning).
But being the responsible program it is it justs trys its best to do what you asked.

What it did was a 'legacy mode' for backward compatibilty.

Just save up all the options, and do them when an image had been finally given.
This is a throw back to the bad old IM version 5 days, where this try of thing happened all the time.

If your READ in the image BEFORE you operate on it, it will work as expected...

Code: Select all

 convert \
            in.jpg \
            -crop +0+100 \
            -bordercolor silver \
            -border 10 \
            out.jpg

and all will be done in the order you expect because you gave it in the order YOU want it to be done in.

Thanks for that. It did the trick although I thought I'd already tried that approach.
