Absolute Colorimetric is a rendering intent that leaves colors that fall inside the destination gamut unchanged. It does not expand or compress the whole gamut. Each color is transformed into itself, if it exists in the destination gamut. Otherwise, it is transformed to the closest color at the gamut boundary. In short, out of gamut colors get clipped.

Bitmap images are resolution dependent, unlike vector graphics which are resolution independent. A bitmap does not need to contain a bit of color-coded information for each pixel on every row. It only needs to contain information indicating a new color as the display scans along a row. This means that an image with much solid color will tend to require a small bitmap.

The mixing of adjacent pixels to simulate additional colors to fill the gaps between two colors. For instance, if one wants to display a full color graphic on a 256-color monitor, the computer will simulate the colors it cannot display. If there is a part in an image that displays incorrectly because a red and a yellow pixel are lying next to each other, creating a definite line from a distance, dithering would put an orange pixel in between to smooth out the line and the colors.
