(It chops 19 pixels off the bottom. God knows why and probably so do the Atari ST developers. :lol:
19 pixel is the height of the menubar, when using the 8x16 system font. I guess the desktop draws the image below the menubar, not at 0,0.

That was the conclusion I came too
@thorsten.otto
However this conversion puts it under the 10mm of the menu bar.

Maybe my monitor displays it differently than on the Atari compatible CRT I used to use.
I just kept putting the number down until it stopped cropping (which took some considerable time!) :coffee:

I think the menu bars height varies on TOS versions as well. I think on the ST I had to use 12px, but on the Falcon it was 19. I think in part on the falcon it was down to the 3D effect. Its possible it could vary between resolutions also ?

Thanks @exxos. So many idiosyncrasies with the Atari! :lol:
I've never had a desktop pic which had important info on the bottom edge before, so never noticed. :)

Yes, the height on the menu bar will vary. The above mentioned 19pixel is only for SingleTOS, and when using the 8x16 system font (ST-High, or TT-High resolutions). Naturally, it will change when using the 8x8 system font (eg. ST-Low or medium). Other AES like XaAES may put some 3D effect on it, so there might be a small difference. And obviously it will change when you replace the system font to something else.
But i think in most cases, that will not be a problem for his purpose. Obviously, when using other resolutions, you will need a different image anyway.

Thanks @thorsten.otto
If it wasn't for this community I wouldn't be set up so well. :)
