FAQ
$S to KTX2 Conversion
What are $S files?
The $S format represents a Hobetta picture image associated with one of the first brands of personal home computers available in Europe: the ZX Spectrum. Released in 1982 by Sinclair Research Ltd., this line of computers supported an 8-bit color rendering, which was considered an advanced technological innovation when compared to earlier version such as ZX 81 that only supported black-and-white. Though rarely used nowadays and compatible with a limited number of image viewers and editors, the $S format can be converted to more popular extensions for easier handling.
What are KTX2 files?
KTX2 (Khronos Texture 2.0) is a container file format for GPU-ready texture data, published by the Khronos Group as the successor to the original KTX format. A single file can hold 1D, 2D, 3D, cubemap and array textures together with their full mipmap chains, stored in the memory layout expected by graphics APIs such as Vulkan, OpenGL and OpenGL ES, so the contents can be uploaded to the video card with little or no additional processing. Besides plain block-compressed data, KTX2 supports supercompression: Basis Universal (ETC1S and UASTC) allows one file to be transcoded at load time into the format the target device actually needs, while Zstandard and ZLIB simply reduce file size. The format is the texture payload used by the glTF KHR_texture_basisu extension, which makes it common in 3D assets for the web, game engines and AR applications.
