cmapui

A GUI to generate colormaps by interactively picking colors

Syntax

• cmap5 = cmapui
  cmap32 = cmapui(32)
  

Description

cmapui is a graphical user interface to create a colormap. The default size is 5 colors.

Colors slots in the colormap are selected by clicking in the colorbar on the right side of the panel. The current color slot is outlined in black. The color components for that color in HSV space are shown by the position of the dot in the colorwheel and of the red bar in the value slider. To change the color, use the mouse to drag the dot and/or the red bar. To close the GUI and return the matrix of colors as RGB components, click the ACCEPT button. Clicking CANCEL closes the GUI and returns an empty matrix.

cmapui is a modal GUI. There is no access to the MATLAB command line while cmapui is active.

Examples

• cmap = cmapui(20);
  cmap = cmapui(colorcube(10));
