Image Processing Toolbox

Displaying and Printing Images

Overview

The Image Processing Toolbox supports a number of image display techniques. For example, the function imshow displays any supported image type with a single function call. Other functions handle more specialized display needs. This chapter describes basic display techniques for each image type supported by the toolbox (e.g., RGB, intensity, and so on.), as well as how to set the toolbox preferences for the imshow function. It also discusses special display techniques, such as multiple image display and texture mapping. The final pages of this chapter include information about printing images and troubleshooting display problems

Color approximation
There are two ways in which this term is used in MATLAB:
The method by which MATLAB chooses the best colors for an image whose number of colors you are decreasing

MATLAB's automatic choice of screen colors when displaying on a system with limited color display capability

Screen bit depth
The number of bits per screen pixel

Screen color resolution
The number of distinct colors that can be produced by the screen
