PNG: Portable Network Graphics

Portable Network Graphics (PNG, officially pronounced /pɪŋ/[2][3] PING, colloquially pronounced /ˌpiːɛnˈdʒiː/[4] PEE-en-JEE) is a raster-graphics file format that supports lossless data compression. It 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”.[5]

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. 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. 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.[6]

PNG files use the file extension PNG or png and are assigned MIME media type image/png. It was published as Informational RFC 2083 in March 1997 and as an ISO/IEC 15948 standard in 2004.

PNG full form is Portable Network Graphics. It is a format for storing bit-mapped (raster) images on the computer. It is also known as a successor of GIF format images. It uses the less compression technique to save images like GIF files but without copyright issues. It contains a bitmap of indexed color so it is also called a bit-mapped image.

History | PNG Full Form

Portable Network Graphics Format was developed in early 1995. The main reason behind its development was the limitation of 256 colors only in GIF. PNG has a file extension “.png”.

PNG Gas | PNG Full Form

It is a liquefied natural gas. Originally, it was a project to develop a linked gas field in the Western Provinces of Papua New Guinea.

Benefits and applications of PNG

  • It supports various colours and patterns
  • The PNG format has solid colours and sharp edges which makes it perfect for image editing.
  • ONG supports digital-image compression.
  • PNG helps in making comics, drawing, charts, logo creation, blueprints, graphs etc.
  • By using PNG, scanning a text such as letters, journals, etc. can be done.

Advantages of PNG

  • It provides low-resolution images that look good and load quickly.
  • It format promotes transparency.

Disadvantages of PNG

PNG isn’t as perfect for photographs as JPEG since it produces a bigger file.

Pixels in PNG pictures are numbers that might be either list of test information in the range or the example information itself. The range is a different table contained in the PLTE piece. Test information for a solitary pixel comprises a tuple of somewhere in the range of one and four numbers. Regardless of whether the pixel information addresses range files or unequivocal example esteems, the numbers are alluded to as directs and each number in the picture is encoded with an indistinguishable arrangement.

The allowed designs encode each number as an unsigned whole number worth utilizing a proper number of pieces, alluded to in the PNG determination as to the piece profundity. Notice that this isn’t equivalent to shading profundity, which is ordinarily used to allude to the absolute number of pieces in every pixel, not each channel. The allowed piece profundities are summed up in the table alongside the complete number of pieces utilized for every pixel.

The quantity of channels relies upon whether the picture is grayscale or shading and regardless of whether it has an alpha channel. PNG permits the accompanying mixes of channels, called the shading type.
