Crop whitespace from image in PHP

Question

Is it possible to remove the whitespace surrounding an image in PHP?

NOTE: to clarify I mean something like photoshops trim feature.

Thanks.

Answer 1

Check out the ImageMagick library in PHP. It has good methods of working with and manipulating images (including crop).

You'll have to figure out where the "whitespace" is around the image. It could be challenging, since "whitespace" could be the color white, some other color, transparency, etc...
