xzgv is a simple, small software utility that can be used for viewing digital images or pictures of several formats, e.g., jpeg, GIF, PNG, etc. xzgv is used on computers using a Unix-like operating system and the X Window System. Because xzgv is a fast, lightweight image viewer that is compatible with a large number of image formats, the viewer is popular on older, slower, resource-challenged computer systems. xzgv is a standard utility in the Damn Small Linux distribution, for example.
Xzgv was originally built as an X11-compatible clone of zgv by the same developer. The versions prior to 0.9 were based on the software toolkits GTK+ and Imlib 1.x. Most file formats are supported, and the thumbnails used are compatible with xv, zgv, and GIMP. Xzgv differs from other viewers in that it uses one window for both the file selector and viewer. xzgv incorporates a thumbnail-based file selector and is designed to be functional without using a mouse. The versions prior to 0.9 had full keyboard support, including advanced image tagging and external-command automation that were useful for scripting work. Xzgv is not an image editor, and much of its resource efficiency came from the decision to avoid any image modification support.
According to its man page, xzgv supports the following file formats: GIF, JPEG, PNG, PBM/PGM/PPM (collectively known as `PNM'), BMP, TGA (Targa), PCX, mrf, PRF, XBM (X bitmap files), XPM, TIFF, TIM (the Sony PlayStation), and XWD (X window dumps, as produced by the X Window utility xwd).
The source code for the utility is not under active development, but new versions are released every 2–3 years. The 0.9 release is missing much of the earlier releases' functionality and exists primarily as a start toward a version that does not depend on obsolete libraries.
Portable Network Graphics is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF).
Exchangeable image file format is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras, scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing file formats with the addition of specific metadata tags: JPEG discrete cosine transform (DCT) for compressed image files, TIFF Rev. 6.0 for uncompressed image files, and RIFF WAV for audio files. It is not used in JPEG 2000 or GIF.

Image file formats are standardized means of organizing and storing digital images. An image file format may store data in an uncompressed format, a compressed format, or a vector format. Image files are composed of digital data in one of these formats so that the data can be rasterized for use on a computer display or printer. Rasterization converts the image data into a grid of pixels. Each pixel has a number of bits to designate its color. Rasterizing an image file for a specific device takes into account the number of bits per pixel that the device is designed to handle.
CDisplay is a freeware comic book archive viewer and sequential image viewer utility for Microsoft Windows used to view images one at a time in the style of a comic book.
