(tech) — Portable Networks Graphics is a type of picture format with the extension .png that is especially suited for use on the World Wide Web. It offers better quality than both GIF and JPEG, and is not restricted by any software patents but is unsuitable for older browsers.

PNG is similar to GIF and is used for lossless compression. Ideal for the web, PNG supports millions of colors without the output of jagged edges. The disadvantages of using PNG images, is that it is not as widely supported (older web browsers) as GIF is and the file size is larger than a GIF.

A new standard for Internet graphic images that is planned as a replacement for the GIF format. PNG has similar characteristics to GIF, with improved network performance.

Grafisk format, konkurrent til GIF.

Stands for 'Portable Network Graphic'. This format was designed as an alternative to the GIF format . Like GIFs, PNG files are lossless, meaning they don't lose any detail when they are compressed. The format Macromedia's Fireworks likes to save things, and the best way to get a transparent photo for web use. It goes beyond gif in that it can allow you to save files as layers, and these can be imported allowing items to be seperated. Catalogue printing, pads, envelopes - no problem. Contact GSINC

Also known as PNG is Not GIF. PNG is a graphic file format that was developed in the mid-90s in response to patent problems with GIF files and therefore PNG is not patented. PNG has additional features including, alpha transparency, gamma correction, faster interlacing, slightly better lossless compression and more. Some browsers do not support the PNG file format.

( ortable etwork raphics format) This is a lossless compression format that is used on the Internet to display high color graphics like photographs. You can also have transparency with PNGs, but the file sizes can be larger.

ortable etwork raphics: a type of code for storing graphics (like JPG) used extensively in programs like Photoshop and Digital Image Pro, etc.

Stands for Portable Network Graphic. The PNG file format is a great alternative to the GIF format. PNGs compress bitmaps without loss and also support transparency and 24-bit color. You can save a photo-quality image as a PNG without losing image information (like you would with a JPEG) or color (like you would with a GIF).

ortable etwork raphics; pronounced 'ping'. A type of popular image. Proxy Server -- If you have a firewall at your site, you can't normally connect directly to a server on the Internet. You need a helper, a proxy server running on the firewall, to make the connection for you.

Portable Network Graphic. PNG is a compressed graphic format that uses lossless compression, which means that you can save it over and over without losing quality. PNGs support millions of colors with varying levels of transparency, so you can use a single piece of artwork on many different background colors without seeing undesirable "matte" colors around the edges of the artwork. PNGs may be used at full size or smaller in office documents, such as presentations, but they will display and print poorly if enlarged.

The Portable Networks Graphics format is the newest of the "browser readable" image formats (not supported completely in older browsers) and provides lossless compression, various color levels including 24bit "true color", and transparency. While most useful for professional image production it can not generally attain the degree of compression possible with GIF and JPEG formats.

A file format that supports up to 16.7 million colors, with transparency, and that compresses any type of picture file without deteriorating image quality. This format is suitable for all pictures but is not supported by some Web browsers. Because it uses lossless compression, PNG may not be able to reduce files as much as JPEG compression.

Short for ortable etwork raphics, and pronounced ping, a new bit-mapped graphics format similar to GIF. In fact, PNG was approved as a standard by the World Wide Web consortium to replace GIF because GIF uses a patented data compression algorithm called LZW. In contrast, PNG is completely patent-and license-free. Internet.com/Webopedia.com

A new open standard proposed to replace GIF. PNG has 10 to 30 % superior compression than GIF. PNG is supported by current browsers and viewers but is not in widespread use and therefore not supported by all image editing programs. The PNG standard does not support animation as in GIF.

ortable etwork raphics. Pronounced 'ping'. A relatively new graphic image format.

Stands for ortable etwork raphics format, and is generally pronounced "ping." PNG is used for lossless compression and displaying images on the web. The advantages of PNG is that it supports images with millions of colors and produces background transparency without jagged edges. The disadvantages are that PNG images will not show up on older browsers, and still can be comparatively larger in file size than GIFs.

PNG is a graphics format specifically designed for use on the World Wide Web. PNG enable compression of images without any loss of quality, including high-resolution images. Another important feature of PNG is that anyone may create software that works with PNG images without paying any fees - the PNG standard is free of any licensing costs.

A graphic format that is "lossless." The compression gives no quality loss, but the filesize is large. This graphic format is not widely used on the web at this time.

Portable Networks Graphic. A graphics format that allows for transparency and does not compress file size as small as that allowed by the GIF.

PNG is an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel for transparency. Sample depths range from 1 to 16 bits per component (up to 48bit images for RGB, or 64bit for RGBA). Home: http://www.w3.org/Graphics/PNG

Portable Network Graphic: An image format suited to the web but not yet widely supported.

A type of compressed (usually 24 bit) color image format. While JPEG is completely opaque, PNG files allow some transparency. When a large number of colors is required to display an image properly on a webpage, this file format can often be used. PNG files use a type of Lossless compression to make files smaller for internet use.

Refers to a free compressed graphic format which has replaced the gif in many places and supported by the most current browsers.

Developed as a patent-free alternative to GIF, PNG format is used for loss less compression and for display of images on the Web. Unlike GIF, PNG supports 24-bit images and produces background transparency without jagged edges; however, some Web browsers do not support PNG images. PNG format supports RGB, indexed-color, grayscale, and Bitmap-mode images without alpha channels. PNG preserves transparency in grayscale and RGB images.

An open sourced statistical compressor (pronounced ping) and named after its file extension.

"Like a GIF, a PNG file is compressed in lossless fashion (meaning all image information is restored when the file is decompressed during viewing). A PNG file is not intended to replace the JPEG format, which is ""lossy"" but lets the creator make a trade-off between file size and image quality when the image is compressed. Typically, an image in a PNG file can be 10 to 30% more compressed than in a GIF format."

Portable Network Graphic - "Ping", developed for use on the Internet. It became popular after the standard GIF file format was ruled to breach copyright and will increase in popularity as software developers can incorporate PNG compatibility without paying royalties.
