Gateway routine to plot scene radiance properties
udata = plotScene([scene],[pType='hlineluminance'],[xy])
The scne plots show the radiance or luminance data in various formats.
Example:
scene = vcGetObject('SCENE');
rows = round(sceneGet(scene,'rows')/2);
plotScene(scene,'hlineradiance',[1,rows])
uData = plotScene(scene,'ffthlineluminance',[1,rows])
plotScene(scene,'radianceimagewithgrid')
plotScene(scene,'illuminant')
The values of the plot type (pType) are
{'hlineradiance'} - Horizontal line radiance
{'hlineluminance'} - Horizontal line luminance
{'hlineluminancefft'} - Horizontal line luminance Fourier transform
{'hlinecontrast'} - Horizontal line contrast
{'vlineradiance'} - Vertical line radiance
{'vlineluminance'} - Vertical line luminance
{'vlineluminancefft'} - Vertical line luminance Fourier transform
{'vlinecontrast'} - Vertical line contrast
{'radiancefft'} - Image spatial frequency amplitude(single wavelength)
{'luminancefft'} - 2D fft of scene luminance
{'radianceimagewithgrid'} - Render radiance image
{'illuminant'} - Multispectral scene illuminant
When called from the sceneWindow callbacks, the user selects the
horizontal or vertical position. Because of difficulties in setting
the focus for ieGetXYCoords(scene), when called from the command line
you set the (x,y) position in the calling argument.
