editpseudo: Interactively Modify Colormap Using PseudoColor Palette

editpseudo is an interactive tool for changing the colormaps of data objects. It performs colormap modifications via the psudocolor method. A psudocolr visual object is created and mapped to the screen. The pseudocolor display includes a toggle from which you may select the color space model, a palette of the colors in which image pixels appear, and a set of Red, Green and Blue scrollbars.

The features provided by editpseudo include:

• Pseudocolor Palette, in the form of a grid of color cells. Each color cell represents a pixel in the data object. The color cells are arranged in the order that the pixels appear in the data object's colormap. That is, the upper leftmost colorcell is the first color in the colormap and lower rightmost pixel box is the last color in the colormap. When a range of colors from the palette is chosen for modification, all colors taht lie sequentially between those two color cells in the colormap are altered.
• Red/Green/Blue Scrollbars, reflect the three different components that define the color of the selected pixel. The scrollbars are used to modify the colormap of a data object.
• Color Cell/Color Bar/Color Wheel, are three palette types available for colormap editing.
