FAQ
RAS to KTX2 Conversion
What are RAS files?
The RAS file extension represents the CALS Raster File Format, a standard developed by the U.S. Department of Defense for the interchange of monochrome raster graphics. It is primarily used for storing high-resolution, black-and-white images such as engineering drawings, technical manuals, and scanned documents. CALS RAS files are typically used in military, aerospace, and government applications due to their consistency and archival suitability. The format supports compression and is optimized for printing and long-term storage.
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.
