First, this method needs a planar map projection as its starting point, thus compounding the problems right off the bat. Planar projections are relatively accurate near the center but heavily distorted toward the edges. A famous example of a planar projection is the logo of the {{w|United Nations}}. Planar projections are basically only useful for 3D graphics rendering, if the user needs a quick, inexpensive way to store map textures that will later be attached to a sphere. | First, this method needs a planar map projection as its starting point, thus compounding the problems right off the bat.

(Using a Photoshop tool for a task it is not intended for was also used in [[1685: Patch]] where a GNU patch tool was replaced with Adobe Photoshop's patch tool to compile code.) The content aware resizing tool resizes images by identifying what it thinks are important details and preserving these, while shrinking or stretching less detailed areas. For example, [http://knowyourmeme.com/photos/710073-content-aware-scaling when used on a face], the algorithm detects that the eyes and mouth are important details and tries to keep these in place, while stretching the skin around it. When applied to a map, this means that areas with lots of countries - and therefore lots of detail - such as Europe, West Africa, the Eastern Mediterranean and Central America/the Caribbean are relatively unchanged, while big countries like India, China and the US are very warped. The choices that the resizing tool makes are also dependent on the exact visual features of the original map, such as the choice of not having any topography or infrastructure drawn on, or not including a latitude/longitude grid, so what areas are deemed as unimportant is even more arbitrary than it would be on, say, a photographic picture of the Earth. |
[http://knowyourmeme.com/memes/content-aware-scaling Bad content aware scaling] is already a meme. This projection does do a good job, however, of making almost every country clearly visible and indicating which countries are neighbors. | [http://knowyourmeme.com/memes/content-aware-scaling Bad content aware scaling] is already a meme.
