RplcPic CATALOG
RplcPic picVar [, row ][, column ]
Clears the Graph screen and places picture picVar
at pixel coordinates (
row , column ). If you do not
want to clear the screen, use
RclPic.
picVar must be a picture data type variable. row
and
column , if included, specify the pixel
coordinates of the upper left corner of the
picture. Default coordinates are (0, 0).
Note: For less than full-screen pictures, only the
area affected by the new picture is cleared.
