Adding Iso-Contour Lines to Images

The fourth tab

Isocontour Histogram

is used to overlay iso-contour lines onto the images. A histogram of the pixel values is shown, and the value at which the iso-contour lines are drawn can be adjusted by entering a numerical value, or by dragging the marker highlighted in the graphics above. The selection on the right allows choosing among several colors for the contour lines.

Isocontour Result
