Description

pe_set_pseudo_colr allows you to modify the entries in the installs a pseudo color mapping data record and assigns the given index to this mapping.  Use the pe_setup_pseudo_colr function to create the values in the datarec argument.  See the pe_setup_pseudo_colr function for details of the pseudo color mapping data record.
