Palette Pane

The Palette Pane shows the mapping of image values to screen color or grayscale and provides a method to adjust the palette. The palette pane has two forms: vertical and horizontal. The vertical pane adds 2 buttons, one for opening the Palette Properties dialog and the other button for resetting the palette to remove the adjustments you have made to an unsaved palette. The palette pane may be resized and moved to a different window border or detached from the window entirely. This pane docks only on the left and right window borders. The stick-pin allows you to reduce the pane to a tab which opens and hides from the window border.

The Palette Pane has a "color bar" to show how image values are mapped into color or grayscale. Number beside the color bar are the image values assigned to the palette color. If you change the Transfer Function with the Palette Pane open you will see these numbers change.

Stretching the Palette

Adjusting the palette to change contrast and brightness is also known as "stretching" the palette:

  1. Move the mouse pointer onto the color bar in the Palette Pane.

  2. Mouse down (left button) on the color bar. Do not release the mouse

  3. With the button down, drag the mouse horizontally to change brightness and vertically to change contrast.

  4. When the palette is set as desired, release the mouse button.
