How can you use Imagemagick crop to get first 100px from an image?

  • 772

It's been awhile since I've played with Imagemagick. I do remember crop and I can take an image named foo.png and use:

convert foo.png -gravity north -crop 1000x100 bar.png

but my output is:

bar-0.png
bar-1.png
bar-2.png
bar-3.png
...

When I only want what's in bar-0.png.

I've researched around and found:

What is the correct way to crop an image and just get the first return? I'm not not worried about the aspect ratio or the size of the images. I'm just trying to get a sample of the image's first 100px.

  1. You need to add the information from which X and Y you want to start, otherwise Imagemagick will repeat the crop:

    convert foo.png -gravity north -crop 1000x100+0+0 bar.png
