[italic]Hi!
I'm creating new project and want to use drawing and graphics to edit pictures...[/italic]
[u]I tried to import system library:[/u]
[b]Imports System.Drawing.Drawing2D[/b]
[u]and created object:[/u]
[b]Dim G As Graphics = picture.CreateGraphics[/b]
[u]I created simple utility to test writting one line:[/u]
[b] Private Sub MainLine()
X = Int(picture.Width)
Y = Int(picture.Height)
mLinePos = X / 2
Dim P As Pen = New Pen(Color.Red)
G.DrawLine(P, mLinePos, 0, mLinePos, Y)
curX = X / baseX
curY = Y / baseY
G.ScaleTransform(curX, curY)
End Sub[/b]
[u]Then Visual Basic reported error... and after removing code which was to test and object declaration and import too, project always reports the same error, look below...[/u]
[italic]Can anybody help me?
Many many thanks for everything![/italic]
