FAQ
SD1 to KTX2 Conversion
What are SD1 files?
The SD1 extension is attached to RAW images captured using some models of Sigma cameras. Sigma is a Japanese brand producing various types of photographic devices and cameras. The brand is best known for its lenses that can be used on cameras manufactured by several other companies, including Nikon, Canon and Panasonic. SD1 is part of a group of extensions attached to images shot in RAW mode on Sigma devices, including SD0 and SD2. All are considered rare and probably difficult to open using regular image viewers.
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.
