Binaryworld - DrawSkewImage - skewing an image by a given amount along one or both a ... [ VB.net -> Graphics ]

' Skew an image by a given amount along one or both axes (the dx and dy
' parameters)
' The x and y parameters are the coordinates of the upper-left point
' Note: requires Imports System.Drawing.Imaging

' Example:
' Dim gr As Graphics = Me.CreateGraphics
' gr.Clear(Color.White)
' Dim bmp As New Bitmap("logo.bmp")
' DrawSkewImage(gr, bmp, 100, 400, -50, 0)
' DrawSkewImage(gr, bmp, 300, 400, 0, 50)
' DrawSkewImage(gr, bmp, 500, 400, -50, 50)
' bmp.Dispose()
' gr.Dispose()

Sub DrawSkewImage(ByVal gr As Graphics, ByVal bmp As Bitmap, ByVal x As Single, _
  ByVal y As Single, ByVal dx As Single, ByVal dy As Single)
  ' Find the position of (x1,y1) and (x2,y2).
  Dim x1 As Single = x + bmp.Width
  Dim y1 As Single = y + dy
  Dim x2 As Single = x + dx
  Dim y2 As Single = y + bmp.Height

  ' Create the points array.
  Dim points() As Point = {New Point(x, y), New Point(x1, y1), New Point(x2, _
    y2)}
  ' Draw the skewed image
  gr.DrawImage(bmp, points)
