PointCoord

Returns the x or y position of the Draw pen.

Syntax

Declare Function PointCoord( ByVal func As Long ) As Single

Description

The PointCoord function can be used to query x and y position of the Draw pen in graphics mode. The result value depends on the passed func value:

func value:	return value:
0	x physical coordinate, same as PMap( PointCoord( 2 ), 0 )
1	y physical coordinate, same as PMap( PointCoord( 3 ), 1 )
2	x view coordinate
3	y view coordinate

Remarks

Usage

result = PointCoord( func )
