vpolcolor − colors polygon file according to the intensity of the image

vpolcolor [if=<polygon file>] [sf=<input image>] [of=<output file>] [bf=<additive factor>] [tf=<multiplicative factor>] [-a] [-p]

vpolcolor colors <polygon file> according to the intensity of <input image>. For each polygon the centerpoint is found (intersection of medians). The intensity of corresponding point of <intensity image> is taken and encoded as the attribute of the polygon to the <output file>. Color index is also assigned based either on autoscale (-a option) or on a linear function (<additive factor> and <multiplicative factor>).
