Why this is creating many images instead of just two?
I want to get two images; 28 pixels from the base and another image with what's left.

Please help.

It is doing tile cropping and the part you specified is not half of the image.

Because you are doing tile cropping and you have specified only a small part of the image. It will try to crop out every section that is 28 pixels by full height.

I do not think you can do unequal tile cropping to get only two sections.

To get only two sections, you must split in half, so you can do -crop 50%x100%+0+0 and get two halves.

But you cannot do -crop 25%x100%+0+0 unless you want 4 parts.

To do what you want, you need to do two separate one section crops.

convert image -crop 28x+0+0 +repage output1
convert image -crop WWx+0+0 +repage output2

where WW=W-28

see

and the whole section about cropping at

you can also use -chop to get the second half of the image.
or use an alternative -chop using -crop technique

Thank you guys. Anthony's first method worked for me.
