One of them was Thomas Boutell, who on 4 January 1995 posted a precursory discussion thread on the Usenet newsgroup "aphics" in which he devised a plan for a free alternative to GIF. The patent required that all software supporting GIF pay royalties, leading to a flurry of criticism from Usenet users. The motivation for creating the PNG format was the realization that, on 28 December 1994, the Lempel–Ziv–Welch (LZW) data compression algorithm used in the Graphics Interchange Format (GIF) format was patented by Unisys. See also: Graphics Interchange Format § Unisys and LZW patent enforcement PNG was published as an informational RFC 2083 in March 1997 and as an ISO/IEC 15948 standard in 2004. PNG files have the ".png" file extension and the "image/png" MIME media type. A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics therefore, non-RGB color spaces such as CMYK are not supported. PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF)-unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF". Portable Network Graphics ( PNG, officially pronounced / p ɪ ŋ/ PING, colloquially pronounced / ˌ p iː ɛ n ˈ dʒ iː/ PEE-en- JEE) is a raster-graphics file format that supports lossless data compression. Just visit the Vectorizer website, upload your raster image and download the ready SVG file.Īll uploaded data is deleted after 1 hour.89 50 4e 47 0d 0a 1a 0a (8 bytes Hexadecimal) If you have a good enough Internet connection to upload your image quickly, the vectorization process will literally take a few seconds (although it depends on the size and complexity of the picture).Īll you need is the Internet! You can create high quality vector images even from your mobile phone. These programs, on top of everything else, are expensive. You do not need to have special knowledge or learn to use modern graphic editors and entire bundles (Corel Draw or Adobe Illustrator) to work with vector graphics. The resulting picture corresponds to the highest standards of the graphic design industry and is in no way inferior to what is offered by paid services.Įasy to use. High quality of the result is one of the main advantages. You do not need to register or install any software. Vectorizer is a completely free online service that provides services to all on equal terms. If your source of inspiration is in the form of a raster image, Vectorizer will be a useful tool for you! What are the advantages of Vectorizer?įree vectorization. Many contemporary artists often prefer to work with sketches in the form of vector images or create their own work. And so you can easily integrate the picture into your project after vectorizing it. Support for artists and engineers!Ĭomputer-aided design systems for automating work with drawings, plans and other technical documents use vector graphics formats. ![]() They are ideal for advertising purposes: for souvenir mugs, T-shirts and badges, as well as for making plastic items. Vector images are used as a "map" by dedicated tools: plotters, machine tools with software control. For example, if a logo image is low quality and pixels are visible when enlarged, it can be converted into a vector object that can be scaled up to the desired size without losing sharpness. ![]() Vector graphics are mainly used in visual design. Such an image can be enlarged or reduced without loss of quality. It is a complex computational process that converts a raster image, consisting of pixels, into a vector image consisting of lines, curves, and other geometric shapes.
