A complete grf file:

All this is supposed to do is replace the bus that shows up in the colour selection window, so you can see a particular vehicle in all its player-colour permutations. Find attached an enlarged view of the unit in question, and how the thing looks in the colour selector.
Note that the actual .pcx file does not have the white border. Both pictures scaled to 200%.

to me it looks like the pcx you're using has an odd width?
ttd (or grfcodec) can only handle even width...

It's obviously f*** up (excusez le mot). Are you sure you coded everything right and didn't mix up xa dn y size/rel.

Well, it's worked before, and I've followed the order specified in the header comments. I've also put the entire nfo above.

That doesn't mention the PCX file, just the sprite within it.
I'm not sure if grfcodec can handle sprites at y=0, to be honest. Try:
- encode
- decode
- in decoded pcx, replace the sprite with the correct graphics
- encode again

The original file was 12x32, just like I said
Anyway, decoding and recoding has done the trick.
