This may seem a bit obvious, but why not draw all your sprites onto a grid 
in the PCX?  For example, if you have 16x16 sprites then draw a row of 
16x16 boxes (on the boundary, of course).  Then when you tell the grabber 
that you want to grab a sprite, remember and set width & height to 16 (or 
whatever).  This is what I do, and it works fine.   Just remember and draw 
to the boundary...
