The use of JPEG is discouraged, since it is a lossy compression format and so will result in a blurry map or diagram. The quality of GIF images is better than JPEG. GIF images allow for the creation of animations. PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours.
These are azimuthal orthographic projections of the Earth from four sides plus the poles. 726x726 pixels, aliased. XCFs have separate layers for water, land, coastlines, political borders, political borders over water (not shown in PNGs), and latitude & longitude gridlines (not shown in PNGs).

Early world maps. The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius ...
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
Conceptually, at every pixel in the output image, the program looks up the grayscale value of the equivalent pixel in the depth map image, and uses this value to determine the amount of horizontal shift required for the pixel. One way to accomplish this is to make the program scan every line in the output image pixel-by-pixel from left to right.
Website. www.w3.org /Graphics /GIF /spec-gif89a.txt. The Graphics Interchange Format (GIF; / ɡɪf / GHIF or / dʒɪf / JIF, see § Pronunciation) is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite and released on June 15, 1987.

Transparency (graphic) 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.
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. [citation needed] The resulting image is referred to as a rendering. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure.
