PointCoord
Queries `Draw`'s pen position in graphics mode
Syntax
`
Declare Function PointCoord( ByVal func As Long ) As Single
`
Usage
`
result = PointCoord( func )
`
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

Example
`
Screen 12
Print "--- Default window coordinate mapping ---"
Print "DRAW pen position, at the default (0,0):"
Print "Physical:", PointCoord( 0 ), PointCoord( 1 )
Print "View:", PointCoord( 2 ), PointCoord( 3 )
Draw "BM 50,50"
Print "DRAW pen position, after being moved to (50,50):"
Print "Physical:", PointCoord( 0 ), PointCoord( 1 )
Print "View:", PointCoord( 2 ), PointCoord( 3 )
Print "--- Changing window coordinate mapping ---"
Window Screen (-100, -100) - (100, 100)
Draw "BM 0,0"
Print "DRAW pen position, after being moved to (0,0):"
Print "Physical:", PointCoord( 0 ), PointCoord( 1 )
Print "View:", PointCoord( 2 ), PointCoord( 3 )
Draw "BM 50,50"
Print "DRAW pen position, after being moved to (50,50):"
Print "Physical:", PointCoord( 0 ), PointCoord( 1 )
Print "View:", PointCoord( 2 ), PointCoord( 3 )
