Answer 1

DDS - Direct Draw Surface is a container format filled with one or more images, provided with a special DDS header.
As a rule, textures compressed by hardware-decodable methods (S3TC, PVR, ATC, ETC) are stored in this format. However, the container also allows you to store uncompressed color data.
The type of compression method is specified in the DDS header, in the "_fourcc" field, as a four-character string.
An example of a DDS header description:

An example of directly loading a DDS file:

When loading a DDS file, the first step is to read the header, everything beyond the header is an image(s).
If the data compression format is specified in the file header, then the data must be unpacked before using it manually. Uncompressed data (RGB(1|4|8)(A) formats) can be used directly from the file.
Writing a do-it-yourself compression format unpacker is a difficult task. It is easier to take ready-made libraries from the direct developers or intermediaries of these formats.
ATC is unpacked using the Adreno SDK ( https://developer.qualcomm.com/download ).
The PVR is unpacked using the PowerVR SDK ( community.imgtec.com/developers/powervr/graphics-sdk ).
DXT or S3TC handles both of the above packages as well as the DirectX SDK. There is also a set of utilities from nVidia - Texture Tools ( https://developer.nvidia.com/legacy-texture-tools).
