The Utah Raster Toolkit image file, commonly known as a URT file, is a format used for storing bitmap images. Originating from the Utah Raster Toolkit, a collection of tools and libraries for handling raster images, URT files are specifically designed for complex image processing and visualization tasks. This file format supports various types of image data, including color, grayscale, and black-and-white images. URT files are primarily used in academic, research, and development settings where advanced image manipulation and analysis are required.
Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
