Displaying a histogram in the LUT Editor

Focus allows you to display the input and output versions of the histogram that you want to edit in the LUT Editor. You can also display the breakpoints that can be used to edit the histogram. The changes made to the breakpoints are reflected in the ouput.

  1. In the LUT Editor, select one of the following options from the Mask list box:
    • Entire raster: displays a histogram of the entire raster.
    • Current view area: displays a histogram of the area that is displayed in the Focus viewer.
    • Bitmap layer: displays a histogram of a region under a bitmap mask. The bitmaps are listed whether they are saved or not. Both the file and layer names are displayed for the saved bitmaps.
  2. From the View menu, select or cancel the selection of the following options:
    • Input Histogram: displays the original version of the histogram.
    • Output Histogram: displays the resulting histogram after enhancements
    • Breakpoints: displays nodes, which facilitate the enhancement process
