Boundaries Dialog     


The Boundaries dialog shows and permits modification of the partition boundaries. The pixel values (Vmin & Vmax) are mapped from the index values (Imin & Imax) according to the contrast settings in the active image window. If an image window is not active, the settings are taken from the first image in memory; a warning is given if multiple images are present with different settings. The Mat'l and Name columns show the material assigned to the partition.

The top and bottom (if an edge material is not present) lines in the boundary list correspond to the materials used for the intensity ranges beyond the values contained within the boundaries. The boundaries on those lines cannot be changed; the intensity values listed are the maximum and minimum intensities in the image. If an edge material is present, the last line in the list reads Edge. No boundaries are present for the edge material, only the material and name.

Clicking in the first (Vmin) column selects a partition, the properties of which are shown on the right side of the dialog. The color block at upper right shows the partition color.

Range
The Min and Max boundary values in the Range box can be specified as either pixel intensity Value or colormap Index. New values entered are put into effect with the Modify button. New entries to the value extremes may be changed slightly by the program if the range of values is different than the range of intensities-the new values are converted to intensities and then back to values.

Material
The fields show the Material number and Name of the selected partition. New values are put into effect with the Modify button.

Select shows the Material Library dialog in which a material can be selected for the current partition. The dialog displays the current partition material when invoked.

New creates a partition with boundaries given in the Range box.

Remove deletes the selected partition.

Modify puts changes to the boundaries or material of the active partition in effect.

Dismiss hides the dialog.

Help shows the help page for the dialog.
