Description
The MIFF (Magick Image File Format) is a versatile image format used primarily by ImageMagick, a software suite for creating, editing, converting, and displaying bitmap images. It is designed to store bitmap images with a high degree of flexibility, supporting various depths and color spaces, including transparency and multiple layers. MIFF files are often used for temporary storage during image processing tasks, as they can efficiently preserve the full quality and attributes of images.
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.
