Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7.
Exif. Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [ 5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones ), scanners and other systems handling image and sound files recorded by digital cameras.
This is a list of file signatures, data used to identify or verify the content of a file.Such signatures are also known as magic numbers or Magic Bytes.; Many file formats are not intended to be read as text.
The National Imagery Transmission Format Standard ( NITFS) is a U.S. Department of Defense (DoD) and Federal Intelligence Community (IC) suite of standards for the exchange, storage, and transmission of digital-imagery products and image-related products. DoD policy is that other image formats can be used internally within a single system ...
The format supports an optional alpha channel like PNG (but unlike JPEG); and progressive coding, similar to PNG (unlike it, progressive compression doesn't increase file-size), but as FLIF's algorithm is more complex (and partly, may not have had as much tuning of the implementation yet), it has a higher computational cost; at least lower ...
The JPEG File Interchange Format ( JFIF) is an image file format standard published as ITU-T Recommendation T.871 and ISO/IEC 10918-5. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm. The base specifications for a JPEG container format are defined in Annex B of the ...
The BMP file format or bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter ), especially on Microsoft Windows [ 2] and OS/2 [ 3] operating systems. The BMP file format is capable of storing two-dimensional digital images in various color depths, and ...
The intended purpose was to create an open source lossless compression method that was faster and easier to implement than PNG.Figures specified in the blog post announcing the format claim twenty to fifty times faster encoding, and three to four times faster decoding speed compared to PNG, with similar file sizes.
