Bump mapping is a graphics technique that is similar to texture mapping. Its primary purpose is to make a surface appear rough, while texture mapping adds color to a visual polygon. Bump mapping adds significant detail to an object that would normally require many polygons to create a similar visual effect. It uses a minimal amount of computer resources to render the object visually. Bump maps are sometimes referred to as texture maps that are depicting light direction on the image.

Bitmap images are a map or a collection of individually colored, minute dots or pixels (picture elements) that are arrayed in a matrix or grid. Since each individual pixel is too small for the naked eye to perceive without the help of magnification, an array of these pixels forms a perceivably smooth graphic image.
Resizing Bitmap Images
The quality of a bitmap image depends mainly on its resolution, which is the number of dots or pixels per inch of space. Therefore, resizing bitmap images res

Graphics Interchange Format (GIF) is a bitmap based image file format. It was developed and introduced by CompuServe in 1987. GIF is one of the most popular image file formats used on the Internet today. The first version of GIF was 87a; CompuServe introduced an advanced version called 89a in 1989. The 89a version enabled the storage of several images in one file, so as to create simple animations.
GIF supports up to 8 bits per pixel. This permits a single image to use a palette of an upper l

A chromatic aberration or distortion is a disturbance in an optical image in which colors tend to blend together and distort the image. Chromatic aberrations are produced because lenses have a different refractive index or the spot in which a beam of light is focused, for each wavelength of light. Chromatic aberrations can occur anywhere in an image, but are most common around boundaries that separate dark areas from light areas. Chromatic aberrations cause problems for many different sections o

Dots per inch is a measurement used for spatial printing and video dot density in which the number of dots that can be packed into a single inch of space is measured. While only related indirectly, the DPI value does tend to correlate with the resolution of a screen. DPI can be best seen when zooming in real close on something. The tiny dots are then visible to the naked eye. These tiny dots make up the images when looking at a printed picture or the screen.
