to plot a patch on a background image. When I try to save it to .pdf (using 'print' or 'export_fig'), it gives 'Warning: RGB color data not yet supported in Painter's mode'. Also the patch can not be displayed correctly on the background image.
Some solution using rgb2cm (from Matlab FX), but still not work well on my problem
Please tell me if you have a good idea. Thanks very much!
