PNG is a replacement for GIF files Digital Graphic Storage
GIF is one of the oldest file formats for graphics and digital photos of the deposit. GIF has many technical advantages, but also has a big disadvantage business. GIF LZW compression used, which involved with patents and applications for license. The free creation and use of GIF files was always in question.
While GIF is an ideal format for storing images, the use of GIF files provides some license issues. In particular, the GIF LZW compression algorithm is thatpatented and not free to use. GIF has become so popular that it is practically used in many places not practical aspects of licensing, but whatever the practical problem in the industry that has led some groups to organize themselves in order to find a way to solve once and for all.
One solution, proposed and implemented a completely new file format that will replace the old GIF only to create. This format has been in PNG – Portable Network Graphics – and it wasdevelops, more efficient, such as GIF, but free for use without risk of patent or license issues. PNG was designed in the era of the Internet and designed as such with the Internet and use in networks.
Both GIF and PNG have been developed and are mostly used for storage of graphics. Some people confuse the pictures with your digital photos, even though the two are completely different. The graphics are generally computer generated images, which are constructed from some basic geometric objects, such asRectangles, triangles and circles. These items can be a complicated way, combining full-color, brushed, can be used in various textures and much more. Digital photograph, on the other side, the digital camera and take pictures of real objects. Digital photos can be built, not of discrete objects. There are technical implications for the difference mainly being carried out by compression. For example, it is easier to compress images (for it is built fromknown properties and homogeneous color) to compress your digital photos (since they include areas of different colors), is usually a noise and slight color variations in each pixel.
Finally, I would like a brief explanation of what are the GIF and PNG
GIF – Graphics Interchange Format: an old file format that is initiated by CompuServe. It uses a lossless LZW compression, and is therefore more efficient than BMP file. GIF files are very efficient for the deposit baseGraphics (lines, circles and other graphical forms) is also effective for storing small digital photos, but are rarely used to store digital photos, as they once trained to be more effective for this purpose. GIF files can contain multiple frames "support for basic research and incentives.
PNG – Portable Network Graphics: This relatively new format was developed to be used in online applications such as web pages. It uses a lossless compression. The original goalPNG was to replace GIF (due to some complications in licensing the format GIF). PNG is now generally of online sites are used to replace the small photos or digital images in GIF format.
