The texture mapping parameters can be adjusted to make the texture map smaller than the geometry it is mapped over. So texture images in official files should always be cropped to not contain any empty space around the edges.

On other thing. The belt texture should be black and transparent. When making a texture, you generally only want to include the part of the printed pattern that is actually printed. In this case, that is just the black lines, since the yellow comes from the underlying part. This guarantees that no matter what exact colors are used for the part, there won't be a mismatch. (It also allows the part to be used in completely different colors from the original, as long as whatever color is chosen contrasts sufficiently with the black to allow the pattern to be visible.)

On the batman logo texture, you would want the bat to be black instead of transparent, even though that section presumably isn't printed on the actual part. That's because that part really is supposed to be black, and not "whatever's underneath".

OK, I made the belt with black lines and transparent background. The yellow background was just to show.
Concerning the bat, I think it should indeed be black on yellow and background transparent. You can map it on a 1x4 brick to then use in any color.

I made a few other PNG patterns for other parts from Brickheadz. I'll upload those to my website and make the parts on which they are used.

[EDIT] The PNG files I created so far are already in the shared Google folder Merlijn provided:
https://drive.google.com/drive/u/1/folde...S1MZnVEWDg
These do not have the correct dimensions like Travis pointed out.

I think we should consider taking more effort in making patterned parts using texture mapping.
As long as the textures are correct and represent the part we can create patterned parts more rapidly and easily.
Making patterns using LDraw geometry is very time consuming and labour intensive.
And since the prints on patterned parts are getting more complex there comes a time when a pattern cannot be made with LDraw geometry.
Since most modern new generation LDraw programs support texture mapping, I think this is the way we need to go?

At least for purpose I use it: to create models and building instructions using LDCad and LPub3D using LDView as renderer.
