Hello,
i did some tests for better understanding what's going on when resizing
DrawingArea.
Running attached code (circle.txt) creates the file "circles.png" .
On screen, i got a different drawing, shown in "extern_screenshot.png" taken
with KSnapShot directly from the screen.
May anybody be so kind to explain this and/or give me a hint what to read
first to get the code work as needed.
thanks wally
code:
Public Sub btn_test_Click()
'100, 80 - - > 200, 160 resizing from to
Draw.Begin(DrawingArea2)
Draw.Circle(50, 40, 30)
Draw.End
DrawingArea2.Resize(200, 160)
myPicture = DrawingArea2.Screenshot()
myPicture.Save(ProjPath &/ "circles.png")
End
<<attachment: circles.png>>
Public Sub btn_test_Click()
'100, 80 - - > 200, 160
Draw.Begin(DrawingArea2)
Draw.Circle(50, 40, 30)
Draw.End
DrawingArea2.Resize(200, 160)
myPicture = DrawingArea2.Screenshot()
myPicture.Save(ProjPath &/ "circles.png")
End
