Patrick Versus True Color Graphics

I am currently in the process of making a rather large set of BMP monster sprites into PNGs. The problem is that I have many, many animations and offsetting them all in XWE by hand is tedious and boring. Is there a tool or program that'll let me offset them without me spending the next 6 hours of my life adjusting them pixel by pixel?

SLumpEd has an automatic offset function, which can be used on PNGs.

Just make sure not to let both SLumpEd and XWE touch your TEXTURE1 or PNAMES lump. (Not directly related, but it's a bad enough problem to warrant mentioning whenever XWE and SLumpEd are brought up together, just to be safe.)
