Description
The X3F file format, also known as the SIGMA X3F Camera RAW File, is a proprietary image format developed by Sigma Corporation for storing raw image data captured by Sigma cameras equipped with the Foveon X3 sensor. Unlike standard JPEGs or TIFFs, X3F files contain unprocessed data from the camera's sensor, offering photographers greater flexibility in image editing.
Originally used on the Sun Microsystems computers, RAS is a raster image format that displays bitmap images. It is popularly used for specific types of research projects and it can be developed in Unix OS as well. It supports 1 and 32-bits per pixel and used RLE compression codec.
