Abstract
A new system for resolving differences in pixel format is disclosed for use in a collaborative software tool. The disclosed system further determines a frequency distribution of color values within pixels forming a bit map of the display of the shared region on the server system. The disclosed system further forms a color ramp responsive to the frequency distribution of color values. The color ramp includes a number of color ramp entries, where each one of the color ramp entries includes an output color value associated with one or more input color values. The color ramp is then transmitted to a client system. The client system converts pixels received from the server system based on the contents of the color ramp. Further in the example embodiment, the client system converts pixels received from the server system using a color conversion table generated based on the color ramp if the pixels in the client system are of true color format.
