I am sure you can create the necessary labels and code adjustments to make it work.
Private Sub Form_DblClick()
Private Sub Form_Load()
Private Sub DrawTestPattern()
'GGPCM.Label1 = "create line, randomize"
GGPCM.Label1 = ""
Debug.Print "create line, randomize"
Dim x, y, w, h
'Debug.Print Screen.Width & ", " & Screen.Height
Debug.Print GGPCM.Width & ", " & GGPCM.Height
Debug.Print GGPCM.ScaleWidth & ", " & GGPCM.ScaleHeight
'scalewidth is accurate to the form dimensions
w = GGPCM.ScaleWidth
h = GGPCM.ScaleHeight
'While x < 1000
' x = x + 1
' y = y + 5
' GGPCM.PSet (x, y), vbBlack
'draw a quadrant
PSet (w - (w * 0.1), h - (h * 0.1)), vbRed
'X corner to corner
GGPCM.Line (0, 0)-(ScaleWidth, ScaleHeight)
GGPCM.Line (ScaleWidth, 0)-(0, ScaleHeight)
GGPCM.Line (0, ScaleHeight * 0.5)-(ScaleWidth, ScaleHeight * 0.5)
GGPCM.Line (ScaleWidth * 0.5, 0)-(ScaleWidth * 0.5, ScaleHeight)
'GGPCM.Line (0, 0)-(w, h)
'GGPCM.Line (w, 0)-(0, h)
