PCX
PCX, standing for ''PiCture eXchange'', is an image file format developed by the now-defunct ZSoft Corporation of Marietta, Georgia, United States. It was the native file format for PC Paintbrush and became one of the first widely accepted DOS imaging standards, although it has since been succeeded by more sophisticated image formats, such as BMP, JPEG, and PNG. PCX files commonly store palette-indexed images ranging from 2 or 4 colors to 16 and 256 colors, although the format has been extended to record true-color (24-bit) images as well. PCX image formats PCX was designed during the early development of PC display hardware and most of the formats it supported are no longer used. The table below shows a list of the most commonly used PCX formats. Contemporary image editing programs may not read PCX files that match older hardware. PCX is supported by common image processing software including ACDSee, FastStone, GIMP, ImageMagick, IrfanView, LView, Netpbm, PaintShop ...

PaintShop Pro
PaintShop Pro (PSP) is a raster and vector graphics editor for Microsoft Windows. It was originally published by Jasc Software. In October 2004, Corel purchased Jasc Software and the distribution rights to PaintShop Pro. PSP functionality can be extended by Photoshop-compatible plugins. The X-numbered editions have been sold in two versions: PaintShop Pro, which is the basic editing program, and PaintShop Pro Ultimate, which bundles in other standalone programs, additional artistic tools and/or plugins. The particular bundled programs have varied with each numbered version and have not been sold by Corel as separate products. From release 8.00 onwards PSP came with an interface for automating tasks with scripts written in Python. History Originally called GIF2PCX, the software was a file conversion utility, conceived by Robert Voit, used to move images between the major online platforms of the time, Compuserve and AOL. Each platform had their own file format for images, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PMview
PMView is a raster graphics image viewer, converter, and organizer with basic image editing capabilities. It was originally developed for OS/2 but is also available for Microsoft Windows. What it is and what it does PMView reads and writes and converts between more than 40 image file formats, shows the images on the screen, single and in slide shows, rotates or mirrors them, changes sizes and color depth, crops parts out of the images, and provides global editing of the image, all this individually on the image displayed on the screen, by prerecorded macros called batch scripts on a range of images, or directly in the File Open Container. And it can, of course, also print the images. PMView uses its own file open dialog, showing thumbnails of all images in a given folder in what PMview calls the "File Open Container", unless the user chooses to see only the filenames. The size of those thumbnails can be changed by the user, and the user can choose if the thumbnails are take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PC Paintbrush
PC Paintbrush was a graphics editing software created by the ZSoft Corporation in 1984 for computers running the MS-DOS operating system. Published alongside Microsoft Mouse DOS drivers version 4 from 1985 as a direct response to Mouse Systems bundling PCPaint with its mice, millions of copies were sold, and the program itself ended up licensed and used inside Windows 1.0, as Microsoft Paint; with an updated version licensed again for Windows 3.0, which (in an updated state) is still included in Windows today. History It was developed at a similar time to various bitmap paint programs for home computers such as PCPaint, which had been published in 1984 by Mouse Systems, who bundled it with their IBM PC mouses. PC Paintbrush also competed with Apple Paint on the Apple II and MacPaint on Apple Inc., Apple Computer's new Macintosh Computing platform, platform. When PC Paintbrush was released in 1984, it had support for Enhanced Graphics Adapter, EGA. PC Paintbrush was publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indexed Color
In computing, indexed color is a technique to manage digital images' colors in a limited fashion, in order to save computer computer data storage, memory and Hard disk drive, file storage, while speeding up display refresh and file transfers. It is a form of Vector quantization#Use in data compression, vector quantization compression. When an image is encoding, encoded in this way, color information is not directly carried by the image pixel data, but is stored in a separate piece of data called a color lookup table (CLUT) or Palette (computing), palette: an array of color specifications. Every element in the array represents a color, indexed by its position within the array. Each image pixel does not contain the full specification of its color, but only its index into the ''palette''. This technique is sometimes referred as pseudocolor or indirect color, as colors are addressed indirectly. History Early graphics display systems that used 8-bit indexed color with frame buffers ...

Lossless Data Compression
Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits Redundancy (information theory), statistical redundancy. By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with greatly improved Bit rate#Bitrates in multimedia, compression rates (and therefore reduced media sizes). By operation of the pigeonhole principle, no lossless compression algorithm can shrink the size of all possible data: Some data will get longer by at least one symbol or bit. Compression algorithms are usually effective for human- and machine-readable documents and cannot shrink the size of random data that contain no Redundancy (information theory), redundancy. Different algorithms exist that are designed either with a specific type of input data in mind or with speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics File Format
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 lossless compression. For graphic design applications, vector formats are often used. Some image file formats support transparency. Raster formats are for 2D images. A 3D image can be represented within a 2D format, as in a stereogram or autostereogram, but this 3D image will not be a true light field, and thereby may cause the vergence-accommodation conflict. Image files are composed of digital data in one of these formats so that the data can be displayed on a digital (computer) display or printed out using a printer. A common method for displaying digital image information has historically been rasterization. Image file sizes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FFmpeg
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams.

Netpbm
Netpbm (formerly Pbmplus) is an open-source software, open-source package of graphics programs and a programming library. It is used primarily in Unix, where it is found in all major open-source operating system distributions, but also works on Microsoft Windows, macOS, and other operating systems. File formats Several graphics formats are used and defined by the Netpbm project: * portable bitmap format (PBM) * portable graymap format (PGM) * portable pixmap format (PPM) PBM, PGM and PPM, sometimes collectively referred to as the portable anymap format (PNM) are image file formats designed to be easily exchanged between platforms. The Magic number (programming), magic number at the beginning of a file determines the type. PNM files use a magic number of an ASCII "P" followed by a number defining the file type. The PBM format was invented by Jef Poskanzer in the 1980s. The format allowed monochrome bitmaps to be transmitted within an email message as plain ASCII text, so that it ...
