Editing/Creating new Assault Rifle Compass and Ammo Counter

How do I make the bitmaps have subimages like for the assault rifle's compass and ammo counter? I had instantly thought of sprites, but when I looked at the other bitmap (as an example), It didn't use the numbers and such as a sprite. Can anyonehelp with compiling the bitmap correctly to change the Assault Rifle's (or maybe another's) compass and ammo counter? Thank you.

Looking at the bitmap, it's done as in a sequence. Line all of your images up horizontally, each in a 1px total blue border.
The end result would be something that should resemble this.

It's crude, but you get the idea.

So, just like creating the new combined ui parts? Alright, thanks Timo =D.
