PaintPoly

To paint a polygon with the graphics pen's pattern and pattern mode, use the PaintPoly procedure.

PROCEDURE PaintPoly (poly:\xDDPolyHandle);

poly

A handle to the polygon to paint.

DESCRIPTION

Using the pen pattern and pattern mode for the current graphics port, the PaintPoly procedure draws the interior of a polygon whose handle you pass in the poly parameter. The pen location does not change.

SPECIAL CONSIDERATIONS

Do not create a height or width for the polygon greater than 32,767 pixels, or PaintPoly will crash.

The PaintPoly procedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.

SEE ALSO

You can use the FillPoly procedure, described next, to draw the interior of a polygon with a pattern different from that specified in the pnPat field of the current graphics port.
