marker_merge - merge roi marker pattern with full colour image
Mapper
Ian Curington, AVS/UNIRAS Ltd.
This module modifies a full color input image by masking it with an ROI byte field. The marker type code in the ROI is used to control what color is replaced inside each marker area, and optionally a secondary texture image can be used as the fill color inside of the marker areas. The ROI field is compatable with other ROI field modules (IP Lib). This module is designed to work with other marker modules, marker_gen, marker_select, marker_draw, marker_pick, etc.
