The Quite OK Image Format (QOI) is a specification for lossless image compression of 24-bit (8 bits per color RGB) or 32-bit (8 bits per color with 8-bit alpha channel RGBA) color raster (bitmapped) images, invented by Dominic Szablewski and first announced on 24 November 2021.
In principle, coding can be changed while the storage layer is retained; for example, Multiple-image Network Graphics (MNG) uses the PNG container format but provides animation, while JPEG Network Graphics (JNG) puts JPEG encoded data in a PNG container; in both cases however, the different formats have different magic numbers – the format ...
Container classes are expected to implement CRUD-like methods to do the following: create an empty container (constructor); insert objects into the container; delete objects from the container; delete all the objects in the container (clear); access the objects in the container; access the number of objects in the container (count).
The format has been updated several times, adding support for tiles, mipmaps, new compression methods, and other features. [9] In 2007, OpenEXR was honored with an Academy Award for Technical Achievement. [9] OpenEXR 2.0 was released in April 2013, extending the format with support for deep image buffers and multiple images embedded in a single ...
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.
BPG's container format is intended to be more suited to a generic image format than the raw bitstream format used in HEVC (which is otherwise ordinarily used within some other wrapper format, such as the .mp4 file format). [2] [6] BPG supports the color formats known as 4:4:4, 4:2:2, and 4:2:0. [2]
CMIS defines a domain model plus bindings that can be used by applications to manipulate content stored in a repository. CMIS provides a common data model covering typed files and folders with generic properties that can be set or read. There is a set of services for adding and retrieving documents ('objects').
The image-spec is a software shipping container image format spec (OCI Image Format) that reached version 1.0.0 on July 19, 2017. [ 12 ] The OCI Distribution Spec Project defines the distribution-spec, an API protocol to facilitate and standardize the distribution of content.
