How can I trim only one border?

ImageMagick does not have an option to trim one border. You could certainly use the ImageMagick API to access the pixels and trim one border.

Add a 1-pixel thick black row or column opposite the side you want to trim, then add a 1-pixel thick white row or column next to it. Run "convert" with the -trim option. This will trim the desired side and will also remove the white row/column, but won't remove anything from the sides. Then remove the black row/column.

To trim one broder, your want to
-chop it!
See IM Examples...

The solution GlenRP provided is of corse valid, but a round-about way of doing the same thing.

It's not the same. "-trim" and my solution remove a variable number of rows or columns that contain all the same color pixels. "-chop" or "-crop" (and "-shave") remove a specified number of rows. ../GlennRP

I stand corrected. I'll see about adding an example for this.
Done
