In HTML and XHTML, an image map is a list of coordinates relating to a specific image, created in order to hyperlink areas of the image to different destinations (as opposed to a normal image link, in which the entire area of the image links to a single destination). For example, a map of the world may have each country hyperlinked to further ...
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.
Then paste it into any image editor for conversion to other image formats. The PrintScreen key on your keyboard is a good last resort, too. Click that key, and then open an image editor and click "paste" (usually in the edit menu). Finally, Wikipedia:Graphic Lab/Image workshop can create, extract, or edit almost any image. Just leave a request ...
Maps showing a small geographic area should also have an inset locator map, locating that small geographic area in the context of a larger area, such as a continent or island chain. For example, see this map. Avoid blank space in the image around its main content to give the illusion of a margin around the image.
UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
A GIF is an example of a graphics image file that uses a bitmap. [2] As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each pixel may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the ...
The maps that are used with rectified images are non-topographical. However, the images to be used may contain distortion from terrain. Image orthorectification additionally removes these effects. [11] Image rectification is a standard feature available with GIS software packages.
