GDM: Setting the Color Range

Parameter Information


This dialog controls the range over which distances will be differentially colored based on the color gradient selected. e.g. if the range is black to red in color and the range limits are 0.1 (lower limit) to 0.5 (upper limit), all distances below 0.1 will be represented by black, all distances above 0.5 will be represented by red, and distances within the range will be represented by a color corresponding to their position on the color gradient. The distances outside of the defined range are said to be saturated (in terms of color representation). The Dynamic Range Preview panel clearly represents the current limits applied to the matrix.

Lower Limit

The lower range limit defines the distance below which distances will be uniformly represented by the lower extreme color of the gradient. This value must be in the range [0,1) and be less than the upper limit.

Upper Limit

The upper range limit defines the distance above which distances will be uniformly represented by the upper extreme color of the gradient. This value must be in the range of (0,1] and be greater than the lower limit.

% Saturation

The percent saturation value represents the number of matrix elements which fall outside of the current range. Note that this field is only updated upon hitting the 'Preview' button.

Effective Range Preview

This color gradient displays the current limits. (Initial values or entered values after hitting the 'preview' button.

Button

OK Button

This button closes the dialog and applies the entered limits on the GDM.

Cancel Button

This button closes the dialog and restores the GDM to the state before the range dialog was opened.

Reset Button

This button sets the limit values to the initial limit values displayed upon opening the dialog. The restored limits are then previewed on the GDM and in the Range Preview area of the dialog.
