| * ''x'' -- The pixel offset of the left side of the texture within the TGA. This only permits the texture file to be 256 pixels wide at most. For full tiles, it must be a multiple of 64 (0, 64, 128, 192). For partial tiles, it may be any multiple of 16. | * ''x'' -- The pixel offset of the left side of the texture within the TGA.

| * ''y'' -- The pixel offset of the top of the texture within the TGA. The maximum height allowed for a TGA file is 4096 (for width of 256). Since 512 pixel wide TGA files are converted to 256, that makes 4096 the true maximum height. This offset can be at most 4032 for full tiles, or 4080 for partial tiles. For full tiles, it must be a multiple of 64. For partial tiles, it may be any multiple of 16. | * ''y'' -- The pixel offset of the top of the texture within the TGA.

| * ''xSize'' -- This is the pixel offset of the rightmost pixel within the tile. For full tiles, it must be 63. For partial tiles it must be 15, 31, 47, or 63. It is basically the pixel width of the texture minus 1. It cannot be set so that the texture would cross a tile boundary. | * ''xSize'' -- This is the pixel offset of the rightmost pixel within the atlas. For full atlases, it must be 63.
