in the above George command, the mode parameter refers to the "blending" mode of the id layer.tv_LayerMerge id mode ["STAMP"] ["ERASE"]
Merges layer with identifier id (source) and the current layer (destination). The two layers are merged into the current layer. The two layers are merged with the mode (name or line number) define in mode arguments. STAMP argument enable the stamp mode. ERASE argument will erase the layer source.
Is there another George command for READING the "blending" mode for an id layer?
