A DDS DX10 file is a raster image saved in the DirectDraw Surface (DDS) container format whose DX10 extension header selects a DirectX 10 or newer texture format. It stores the texture data in one of Microsoft's DXGI formats — block-compressed GPU textures (BC1–BC7), high-dynamic-range BC6H data or uncompressed formats — and is mostly used for textures, normal maps and cube maps in modern games. Legacy DDS readers often fail on these files.
A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
