+
+The following nodes can be used to demonstrate the TGA format support.
+
+Minetest supports TGA types 1, 2, 3 & 10. While adding the support for
+TGA type 9 (RLE-compressed, color-mapped) is easy, it is not advisable
+to do so, as it is not backwards compatible with any Minetest pre-5.5;
+content creators should therefore either use TGA type 1 or 10, or PNG.
+
+TODO: Types 1, 2 & 10 should have two test nodes each (i.e. bottom-top
+and top-bottom) for 16bpp (A1R5G5B5), 24bpp (B8G8R8), 32bpp (B8G8R8A8)
+colors.
+
+Note: Minetest requires the optional TGA footer for a texture to load.
+If a TGA image does not load in Minetest, append eight (8) null bytes,
+then the string “TRUEVISION-XFILE.”, then another null byte.
