A man with a skeleton face stands over bloody corpses, wielding a whip. His hat and clothing are Bolshevik in style. Translated caption: "Bolshevism without a mask - large anti-Bolshevik exhibition of the NSDAP Gauleitung Berlin from November 6, 1937 to December 19, 1937 in the Reichstag building". Reason A jarring poster.
An application reading a PNG file is meant to ignore any chunks which it does not understand, [13] making APNG backwards compatible. Applications without support for the APNG extension show only the first frame, disregarding additional animation frames. Diagram illustrating a possible way to assemble an animated PNG from three individual PNG files
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. Only part of a graphic should be ...
The structure of MNG files is essentially the same as that of PNG files, differing only in the slightly different signature (8A 4D 4E 47 0D 0A 1A 0A in hexadecimal, where 4D 4E 47 is ASCII for "MNG" – see Portable Network Graphics: File header) and the use of a much greater variety of chunks to support all the animation features that it provides.
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 ...
For identical 8-bit (or lower) image data, PNG files are typically smaller than the equivalent GIFs, due to the more efficient compression techniques used in PNG encoding. [62] Complete support for GIF is complicated chiefly by the complex canvas structure it allows, though this is what enables the compact animation features.

A public service announcement from the Government of California encouraging people to wear masks to "slow the spread". In late March 2020, some government officials began to focus on the wearing of masks to help prevent transmission of COVID-19 as opposed to protecting the wearer; former FDA Commissioner Scott Gottlieb stated in a report that face masks would be "most effective" at slowing its ...
