FAQ

GRO2 to KTX2 Conversion

What are GRO2 files?

GRO2 and GRO4 are image extensions associated with a series of graphing calculators released by Hewlett-Packard, called the HP-49G series. Features delivered by these devices included solving advanced algebra equations and plotting graphs. GRO2 files most likely contain screen shots or commands associated with HP-49G calculators.

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.
