%kPrintMapVal 'PrintMapVal Object Menuform'
% This MatLab function was automatically generated by a converter (KhorosToMatLab) from the Khoros PrintMapVal.pane file
%
% Parameters: 
% Integer: printmapvalWidth 'Width of Display (number of cells across)', default: 7: 'width of printmapval display'
% Integer: printmapvalHeight 'Height of Display (number of cells down) ', default: 9: 'height of printmapval display'
% InputFile: printmapvalFilename 'Input File', required: 'input file'
%
% Example: kPrintMapVal(printmapvalFilename, {'printmapvalWidth',7;'printmapvalHeight',9;'printmapvalFilename',''})
%
% Khoros helpfile follows below:
% .begin tagged
% 
% .item "The PrintMapVal Visual Object"
% A printmapval object provides a mechanism with wich to roam around in an image
% and print the values of the map columns indexed by the pixel under the pointer. 
% It is only useful with data objects having a map segment.  It is made up of one
% or more (width x height) sets of label objects;  typically, there will be three
% such sets, one each for the Red, Green, and Blue map columns of the colormap.
% The background of each label is the color defined by the values of the map 
% columns at that pixel, and the value displayed is the value of the corresponding
% map column.
% 
% .item "Width of Display"
% Specifies the number of map column values that should be 
% displayed in the horizontal direction on the printmapval display.
% 
% .item "Height of Display"
% Specifies the number of map column values that should be 
% displayed in the vertical direction on the printmapval display.
% 
% .item "Show Color"
% Indicates whether or not the color of the pixel under the
% pointer should be displayed as the background color for the label object in 
% which the map values are displayed.  When set to FALSE, the background will be 
% white.
% 
% .item "Update Mode"
% Indicates whether the printmapval display is to be updated 
% continuously as the pointer moves across the image, or not until the button
% is clicked at a particular location in the image.  
% 
% .item "Display Policy"
% Indicates whether the printmapval object is to display
% the values from the colormap that is being used to display the data object
% (ie, the RGB values that may have been converted and/or normalized), or
% the values from the actual map segment of the data object being visualized
% (ie, the map values before they are converted and/or normalized for use
% in defining the colors that appear on the screen). 
% 
% .item "Input File"
% The file containing the data object for which the map values are to be 
% displayed.
