FAQ
CALS to KTX2 Conversion
What are CALS files?
The CALS image format includes a compressed raster/bitmap file. Though considered rare by mainstream users, CALS files are used by many document-handling, DTP and image processing applications employed by the US government. The format itself was created by the Department of Defense as a standard for storing an interchanging graphics data. CALS stands for "Computer Aided Acquisitions and Logistics Support", which is an office inside the Department of Defense.
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.
