JPEG. JPEG ( / ˈdʒeɪpɛɡ / JAY-peg, short for Joint Photographic Experts Group) [ 2] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or ...
A PDF file is organized using ASCII characters, except for certain elements that may have binary content. The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7. The format is a subset of a COS ("Carousel" Object Structure) format. [23]
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 ...
PK4 – PK4 Doom³ archive (opens similarly to a zip archive.) PNJ – a sub-format of the MNG file format, used for encapsulating JPEG files [ 3] PXZ – a compressed layered image file used for the image editing website, pixlr.com. PY, PYW – Python code file. PMP – PenguinMod Project. PMS – PenguinMod Sprite.
JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. [ 7] PNG files have the ".png" file extension and the "image/png" MIME media type. [ 8] PNG was published as an informational RFC 2083 in March 1997 and as ...
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 ...
