Getting the Dimensions and size of a Picture

[compusoftproject]

I am trying to load a picture into an imagebox with stretch property set to true but the picture is showing in a disproportionate manner. I now wish to determine the width and height of the picture programmatically before loading so I can adjust my image box accordingly. Any ideas about how to do this?

This code (from VB 2005) should point you in the right direction. This snippet is from one of my recent projects that randomly sizes an image, maintaining aspect ratio, upon a timer tick. The image I loaded into the picturebox was an image loaded into the project's resources store.

Dim iWidth As Integer = My.Resources.logo2_1280.Width
Dim iHeight As Integer = My.Resources.logo2_1280.Height
Dim iAspect As Single = iWidth / iHeight
 
Private Sub tmrMove_Tick(ByVal sender As System.Object, _
                 ByVal e As System.EventArgs) Handles tmrMove.Tick
 
    Dim iNewWidth As Integer = Int(Rnd() * 500)
    Dim sNewSize As New Size(iNewWidth, iNewWidth / iAspect)
    Me.imgLogo.Size = sNewSize
 
End Sub

If you first load it into a PictureBox with AutoSize property set to True, or an Imagebox with Stretch set to False, it will automatically adjust itself to the size of the loaded image. Then you can just read off the Width and Height properties.
