int D_set_overlay_mode

(

int

n

)

configure raster overlay mode

This routine determines if D_draw_cell draws in overlay mode (locations with category 0 are left untouched) or not (colored with the color for category 0). Set flag to 1 (TRUE) for overlay mode; 0 (FALSE) otherwise.

Parameters

flag

Returns

int
