PCPaint
PCPaint was the first IBM PC-based mouse-driven GUI paint program. It was developed by John Bridges and Doug Wolfgram. It was later developed into Pictor Paint. The hardware manufacturer Mouse Systems bundled PCPaint with millions of computer mice that they sold, making PCPaint also the best-selling DOS-based paint program of the late 1980s. Background During the dawn of the IBM PC age in 1981, Doug Wolfgram purchased a Microsoft Mouse and decided to write a drawing program for it. The interface was primitive but the program functioned well. In February 1983, Wolfgram traveled to SoftCon in New Orleans where he demonstrated the program to Mouse Systems. Mouse Systems was developing an optical mouse and they wanted to bundle a painting program so they agreed to bundle in Mouse Draw. The original program was written entirely in Assembly language with primitive graphics routines developed by Wolfgram. In 1982 John Bridges worked for an educational software company, Classroom Cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Abrash
Michael Abrash is a programmer and technical writer specializing in code optimization and 80x86 assembly language. He wrote the 1990 book ''Zen of Assembly Language Volume 1: Knowledge'' and a monthly column in '' Dr. Dobb's Journal'' in the early 1990s. A later book, ''Zen of Graphics Programming'', applied these ideas to 2D and 3D graphics prior to the advent of hardware accelerators for the PC.

Computer Programmers
A computer programmer, sometimes referred to as a software developer, a software engineer, a programmer or a coder, is a person who creates computer programs — often for larger computer software. A programmer is someone who writes/creates computer software or applications by providing a specific programming language to the computer. Most programmers have extensive computing and coding experience in many varieties of programming languages and platforms, such as Structured Query Language (SQL), Perl, Extensible Markup Language (XML), PHP, HTML, C, C++ and Java. A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, JavaScript, Lisp, Python, Java, etc.) may be prefixed to the aforementioned terms. Some who work with web programming languages may also prefix their titles with ''web''. Terminology There is no industry-wide standard terminology, so "programmer" and "software engineer" might refer to the same role at different companies. Most typically, ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GRASP GRaphical System For Presentation
GRaphic Animation System for Professionals (GRASP) was the first multimedia animation program for the IBM PC family of computers. It was also at one time the most widely used animation format. Originally conceived by Doug Wolfgram under the name FlashGun, the first public version of GRASP was the Graphical System for Presentation. The original software was written by Doug Wolfgram and Rob Neville. It later became the GRaphic Animation System for Professionals. Many regard this as the birth of the multimedia industry. GRASP - Graphic Animation System for Professionals GRASP 1.0 In 1984 Doug Wolfgram conceived of the idea of an animation scripting language that would allow graphics images to move smoothly across a computer screen under program control. Persyst Systems hired Wolfgram's company to develop some graphics and animation for their new graphics card, the BoB board. The marketing manager from Persyst then moved to AST computer where he brought in Wolfgram to do similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics File Formats
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 The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PICtor PIC Image Format
PICtor is an image file format developed by John Bridges, the principal author of PCPaint, the first Paintbrush program for the PC. It was also the native file format for Pictor Paint and Graphics Animation System for Professionals (GRASP) (also by Bridges) and became the first widely accepted DOS imaging standard. Typical file format The PICtor format is a device-independent raster image format; the file header stores information about the display hardware (screen resolution, color depth and palette information, bit planes, and so on) separately from the actual image information, allowing the image to be properly transferred and displayed on computer systems with different hardware. PIC files commonly stored 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. Although it is device-independent, the PIC format also contains additional information about the device that it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Mode X
Mode X is an alternative 256-color graphics display mode of the IBM VGA graphics hardware that was popularized by Michael Abrash. It was first published in July 1991 in ''Dr. Dobb's Journal'', and republished in chapters 47-49 of Abrash's ''Graphics Programming Black Book'' (now freely available online). The term "Mode X" was coined by Abrash. The primary advantage of Mode X is that it has square pixels: a resolution of 320×240 instead of the standard VGA Mode 13h which is 320×200. Additionally, Abrash enabled the VGA's planar memory mode (also called "unchained mode"). Even though planar memory mode is a documented part of the VGA standard and was used in earlier commercial games, it was first widely publicized in the Mode X articles, leading many programmers to consider Mode X and planar memory synonymous. It is possible to enable planar memory in standard 320×200 mode, which became known as Mode Y in the Usenet rec.games.programmer group.Roberts, Dave. ''PC Game Programming ...
