OS / Hardware
It does not matter, as this is not a rendering error.
Summary
The file games/devtest/mods/testnodes/textures/testnodes_tga_type2_16bpp_tb.tga is flipped upside down.
Possible reason: Converting from bottom-top to top-bottom pixel order using imagemagick can erroneously flip images.
Steps to reproduce
- Place the TGA test nodes in devtest.
- Notice that one of the nodes has a ttexture that is flipped upside down.
Additional Information
If you fix this by flipping the texture, make sure that the resulting image is actually a type 2 TGA with 16bpp (A1R5G5B5) colors for which imagemagick's identify(1) reports an orientation of TopLeft.
