Invalid data in texture?

[Reisal]

I am testing the below image but GZDoom is spitting out something about invalid data in patch. I don't see what's wrong with it.



The file for download is found here, both the test WAD and raw BMP file.

Try to make it a .png. Then in SLADE3 convert the .png to a Doom format if you want. I'm not even sure if .bmp is even supported. SLADE3 never seemed to me to have options for .bmps.

BMP is not a supported image format by ZDoom/GZDoom. See the first 'important' note here as to why.

SLADE, however, is perfectly happy to convert BMP to Doom's picture format; there is no need to go BMP->PNG->Doom Gfx when you can go BMP->Doom Gfx.

Or, for GZDoom, BMP->PNG and leave it this way.

SLADE doesn't have the option to convert/export to BMP because it doesn't seem like it'd be useful for any purpose. Everything supports PNG nowadays and these files are smaller, can preserve Doom-specific info like offsets, and are becoming somewhat of an accepted standard in the Doom community.

I want to make this image limit removing compatible, will changing it to PNG really work if I want to fire up with the WAD with PrBoom+ for example?

If you want to be safe, fall back to Doom Gfx.

There we go.
