Potrace
Potrace () is cross-platform Within computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several Computing platform, computing platforms. Some ..., open-source software which converts raster graphics, bitmapped images into vector graphics. It is written and maintained by Peter Selinger. Properties Various graphical frontends are available for the command-line application Potrace. Notably, it has been integrated with Inkscape, giving Inkscape its ''Trace Bitmap'' action. FontForge can use Potrace to import a bitmap image into a font. Potrace is also used by the music engraving program LilyPond. An open-source progressive web app that uses Potrace is SVGcode. Potrace's input and output is black and white (colored images are Grayscale#Converting color to grayscale, greyscaled before processing). However, Inkscape is capable of producing color ima ...

Scalable Vector Graphics
Scalable Vector Graphics (SVG) is an XML-based vector graphics format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by most web browsers. If used for images, SVG can host scripts or CSS, potentially leading to cross-site scripting attacks or other security vulnerabilities. History SVG has been in development within the World Wide Web Consortium (W3C) since 1999 after six competing proposals for vector graphics languages had been submitted to the consortium during 1998 (see below). The early SVG Working Group decided not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Tracing
In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics. Background An image does not have any structure: it is just a collection of marks on paper, grains in film, or pixels in a bitmap. While such an image is useful, it has some limits. If the image is magnified enough, its artifacts appear. The halftone dots, film grains, and pixels become apparent. Images of sharp edges become fuzzy or jagged. See, for example, pixelation. Ideally, a vector image does not have the same problem. Edges and filled areas are represented as mathematical curves or gradients, and they can be magnified arbitrarily (though of course the final image must also be rasterization, rasterized in to be rendered, and its quality depends on the quality of the rasterization algorithm for the given inputs). The task in vectorization is to convert a two-dimensional image into a two-dimensional vector representation of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LilyPond
LilyPond is a computer program and file format for music engraving. One of LilyPond's major goals is to produce scores that are engraved with traditional layout rules, reflecting the era when scores were engraved by hand. LilyPond is cross-platform, and is available for several common operating systems; released under the terms of the GNU General Public License, LilyPond is free software and part of the GNU Project. History The LilyPond project was started in 1996 by Han-Wen Nienhuys and Jan Nieuwenhuizen, after they decided to abandon work on MPP ( MusiXTeX PreProcessor), a project they began collaborating on in 1995. Its name was inspired both by the Rosegarden project and an acquaintance of Nienhuys and Nieuwenhuizen named Suzanne, a name that means lily in Hebrew (). Version 1.0 LilyPond 1.0 was released on July 31, 1998, highlighting the development of a custom music font, Feta, and the complete separation of LilyPond from MusiXTeX. Version 2.0 LilyPond 2.0 was rele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WebAssembly
WebAssembly (Wasm) defines a portable binary-code format and a corresponding text format for executable programs as well as software interfaces for facilitating communication between such programs and their host environment. The main goal of WebAssembly is to facilitate high-performance applications on web pages, but it is also designed to be usable in non-web environments. It is an open standard intended to support any language on any operating system, and in practice many of the most popular languages already have at least some level of support. Announced in and first released in , WebAssembly became a World Wide Web Consortium recommendation on 5 December 2019 and it received the ''Programming Languages Software Award'' from ACM SIGPLAN in 2021. The World Wide Web Consortium (W3C) maintains the standard with contributions from Mozilla, Microsoft, Google, Apple, Fastly, Intel, and Red Hat.

Grayscale
In digital photography, computer-generated imagery, and colorimetry, a greyscale (more common in Commonwealth English) or grayscale (more common in American English) image is one in which the value of each pixel is a single sample (signal), sample representing only an ''amount'' of light; that is, it carries only luminous intensity, intensity information. Grayscale images, are black-and-white or gray monochrome, and composed exclusively of shades of gray. The contrast (vision), contrast ranges from black at the weakest intensity to white at the strongest. Grayscale images are distinct from one-bit bi-tonal black-and-white images, which, in the context of computer imaging, are images with only two colors: black and white (also called ''bilevel'' or ''binary images''). Grayscale images have many shades of gray in between. Grayscale images can be the result of measuring the intensity of light at each pixel according to a particular weighted combination of frequencies (or wavelen ...

JPEG
JPEG ( , short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) 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 trade off between storage size and image quality. JPEG typically achieves 10:1 compression with noticeable, but widely agreed to be acceptable perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The Joint Photographic Experts Group created the standard in 1992, based on the discrete cosine transform (DCT) algorithm. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media. JPEG compression is used in a number of ...

Progressive Web App
A progressive web application (PWA), or progressive web app, is a type of web app that can be installed on a device as a standalone application software, application. PWAs are installed using the offline cache of the device's web browser. PWAs were introduced from 2016 as an alternative to Native (computing), native (device-specific) applications, with the advantage that they do not require separate bundling or distribution for different platforms. They can be used on a range of different systems, including Desktop computer, desktop and mobile devices. Publishing the app to digital distribution systems, such as the App Store (iOS/iPadOS), Apple App Store, Google Play, or the Microsoft Store on Windows, is optional. Because a PWA is delivered in the form of a webpage or website built using common web technologies including HTML, Cascading Style Sheets, CSS, JavaScript, and WebAssembly, it can work on any platform with a PWA-compatible browser. As of 2021, PWA features are support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
