.JPG/JPEG - JPEG format
.JIF - JPEG image file
Features:
- Pixel formats: 8, 24, 32 bits/pixel. YCbCr, RGB, CMYK, YCCK and Grayscale color spaces supported.
- Compression: Extended baseline JPEG support: Both sequential and progressive scan images supported. DCT transform with 8 bits/component data precision. Huffman compression. It can read extended precision quantization tables (word size) as well as an extended number of Huffman tables (max. 4DC & 4AC).
- Meta info: Comment, Density, PhotoShop extension (Name, Author, Comment, Copyright, Time, Source), EXIF extension (Comment, Source, Time, Copyright).
- Notes:
"Normal" saves a 'sequential mode' baseline JPEG image. "Progressive" saves a progressive extended baseline JPEG image.
Progressive usually results in somewhat smaller files, though they are also slightly slower to load and they are not supported by all applications.
The 'size number' determines trade off between file size versus image quality (the higher number the larger the file and the better the quality). A quality setting of 25 or below may not be compatible with all programs.
