NAME

VI_Copy − copy an area

SYNOPSIS

VI_Copy(sx,sy,tx,ty,wd,ht,merge)
int sx,sy;/∗ source top-left ∗/
int tx,ty;/∗ target top-left ∗/
int wd,ht;/∗ rectangle dimensions ∗/
int merge;/∗ merge mode ∗/

DESCRIPTION

VI_Copy duplicates the rectangle at sx,sy with the dimensions wd,ht to the point tx,ty.  The copied bits are merged with the target area using the specified merge mode, not the merge mode set by merge(3G). See merge(3G) for a description of merge modes.

Both the source and destination rectangles must be completely on the screen.  The current setting of the clipping window is ignored. 

NOTE

VI_Copy applies only to the IBM Academic Information Systems experimental display. 

VI_Copy cannot copy an area onto itself with a mode change, e.g. for highlighting.  A fast way to highlight is to use VI_Merge with XOR mode and VI_Tile.
