Potrace[ needs IPA ] is cross-platform, open-source software which converts bitmapped images into vector graphics. It is written and maintained by Peter Selinger.
Various graphical frontends are available for the command-line application Potrace. Notably, it has been integrated with Inkscape, giving Inkscape its Trace Bitmap action. [2] 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 greyscaled before processing). However, Inkscape is capable of producing color images by decomposing each channel into several black and white images and tracing them separately with Potrace. The commercial Total Vectorize program also uses Potrace as its core.
Potrace is licensed under the GNU General Public License v2.0 or later. A non-GPL version of Potrace called "Potrace Professional" is available under license from Selinger's company, Icosasoft Software, Inc. [3]
Scalable Vector Graphics (SVG) is an XML-based vector image 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.
Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software based on these data models. Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations.
Metafont is a description language used to define raster fonts. It is also the name of the interpreter that executes Metafont code, generating the bitmap fonts that can be embedded into e.g. PostScript. Metafont was devised by Donald Knuth as a companion to his TeX typesetting system.
A vector graphic editor is a computer program that allows users to compose and edit vector graphic images interactively on a computer and save them in one of many popular vector graphic formats, such as EPS, PDF, WMF, SVG, or VML.
Adobe Illustrator is a vector graphics editor and design program developed and marketed by Adobe Inc. Originally designed for the Apple Macintosh, development of Adobe Illustrator began in 1985. Along with Creative Cloud, Illustrator CC was released. The latest version, Illustrator 2024, was released on October 10, 2023, and is the 28th generation in the product line. Adobe Illustrator was reviewed as the best vector graphics editing program in 2021 by PC Magazine.
OpenType is a format for scalable computer fonts. Derived from TrueType, it retains TrueType's basic structure but adds many intricate data structures for describing typographic behavior. OpenType is a registered trademark of Microsoft Corporation.
Sodipodi was an open-source vector graphics editor, discontinued in 2004. It is the predecessor to Inkscape.
Inkscape is a free and open-source vector graphics editor for traditional Unix-compatible systems such as GNU/Linux, BSD derivatives and Illumos, as well as Windows and macOS. It offers a rich set of features and is widely used for both artistic and technical illustrations such as cartoons, clip art, logos, typography, diagramming and flowcharting. It uses vector graphics to allow for sharp printouts and renderings at unlimited resolution and is not bound to a fixed number of pixels like raster graphics. Inkscape uses the standardized Scalable Vector Graphics (SVG) file format as its main format, which is supported by many other applications including web browsers. It can import and export various other file formats, including SVG, AI, EPS, PDF, PS and PNG.
Cairo is an open-source graphics library that provides a vector graphics-based, device-independent API for software developers. It provides primitives for two-dimensional drawing across a number of different back ends. Cairo uses hardware acceleration when available.
A computer font is implemented as a digital data file containing a set of graphically related glyphs. A computer font is designed and created using a font editor. A computer font specifically designed for the computer screen, and not for printing, is a screen font.
Xara Designer Pro+ is an image editing program incorporating photo editing and vector illustration tools created by British software company Xara. Xara Xtreme LX was an early open source version for Linux.
FontForge is a FOSS font editor which supports many common font formats. Developed primarily by George Williams until 2012, FontForge is free software and is distributed under a mix of the GNU General Public License Version 3 and the 3-clause BSD license. It is available for operating systems including Linux, Windows, and macOS, and is localized into 12 languages.
A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program. Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export.
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.
In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics.
Design Web Format (DWF) is a file format developed by Autodesk for the efficient distribution and communication of rich design data to anyone who needs to view, review, or print design files. Because DWF files are highly compressed, they are smaller and faster to transmit than design files, without the overhead associated with complex CAD drawings. With DWF functionality, publishers of design data can limit the specific design data and plot styles to only what they want recipients to see and can publish multisheet drawing sets from multiple AutoCAD drawings in a single DWF file. They can also publish 3D models from most Autodesk design applications.
sK1 is an open-source, cross-platform illustration program that seeks to be a substitute for professional proprietary software like CorelDRAW or Adobe Illustrator. Unique project features are CorelDRAW formats importers, tabbed multiple document interface, Cairo-based engine, and color management.
CorelDRAW is a vector graphics editor developed and marketed by Alludo. It is also the name of the Corel graphics suite, which includes the bitmap-image editor Corel Photo-Paint as well as other graphics-related programs. It can serve as a digital painting platform, desktop publishing suite, and is commonly used for production art in signmaking, vinyl and laser cutting and engraving, print-on-demand and other industry processes. Reduced-feature Standard and Essentials versions are also offered.
LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Linux, macOS, and Windows operating systems.
Boxy SVG is a vector graphics editor for creating illustrations, as well as logos, icons, and other elements of graphic design. It is primarily focused on editing drawings in the SVG file format. The program is available as both a web app and a desktop application for Windows, macOS, ChromeOS, and Linux-based operating systems.
