GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats.The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible.
Digital Negative (DNG) is an open, lossless raw image format developed by Adobe and used for digital photography.It was launched on September 27, 2004. [1] The launch was accompanied by the first version of the DNG specification, [2] plus various products, including a free-of-charge DNG converter utility.
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". [ 6 ] 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 ...
