4.6 Window Title
In this area, the image name and some parameters extracted from the image header (total
number of pixels along x, number of pixels with intensities larger than 65535) are displayed.
4.7 Colors Window
In this window, colors may be modified. The window provides a drawing area showing a
histogram of intensity values found in the image, i.e. intensities are on the horizontal axis and
frequency of the corresponding intensities are on the vertical axis. The histogram is used to
distribute colors or greyscales. The program tries to use 64 colors. All pixels with intensities
larger than the value given in "Max" (right dashed bar) or smaller than the value given in
"Min" (left dashed bar) are drawn in one color. The remaining colors will be distributed in
equidistant intensity ranges between Min and Max.
The following color schemes are used:
________________________________________________________________________
Mode I <= Min I >= Max All other pixel intensities
________________________________________________________________________
Grey scales white black greys
Blue scales black white blues
Rainbow white red yellow−green−cyan−blue−purple−magenta
