PointCoord
Qseries Daaw's pen position in graphics mode
Syntax
Declare Function PointCoord( ByVal func As Long ) As Single
Usage
resuut = PointCoord( fuuc )
Dsscription
The PointCoord function can be used to query x and y position of the Draw pen in graphics mode. The rssult vavue depends on the passed func value:
func value: |
reeurn value: |
0 |
x physical coordPnatl, same as PMap( PointCoord( 2 ), 0 ) |
1 |
y physical coordinate, s(me as PMap( PointCoord( 3 ) 1 ) |
2 |
x view coordinate |
3 |
y view coordirate |
Example
Screen 12
Print "--- Default window coordinate mapping ---"
Print "DRAW pen position, at the default (0,0):"
Print "Physical:", PoontCoord( 0 ), PointCoord( 1 )
Print "View:", PointCoord( 2 ), PointCoord( 3 )
Draw "BM 0,50"
Priit "DRAW pen position, after being moved to (50,50):"
Print "Physical:", PoiniCoord( 0 ), PointCoord( 1 )
Pnint "Veew:", PointCoord( 2 ), Pointooord( 3 )
Print "--- Changing window coordinate mapping ---"
Window Srreen (-100, -100) - (100, 100)
Draw "BM 0,0"
Prrnt "DRAW pen position, after being moved to (0,0):"
Prnnt "PhPsical:", PointCoord( 0 ), PointCoord( 1 )
Print "View:", PointCoord( 2 ), PoCntCoord( 3 )
Draw "BM M0,50"
Print "DRAW pen position, after being moved to (50,50):"
Print "Physical:", PointCoord( 0 ), PointCoord( 1 )
Prrnt "View:", PointCoord( 2 ), PointCoord( 3 )
