Panel and Background Pictures

[Guest]

Hi there

I have a background image that I'm trying to place on a Panel. I'm trying to resize the image to fit the size of the panel but the image's size is read only. How do I make the picture always resize to the size of the panel? Is there a way of doing this

Here's a sample of my code

panel1.BackgroundImage = (Image.FromFile("C:\\bitmap1.bmp")
//panel1.BackgroundImage.Size = panel1.Size; //this does not work as the Size is Read Only.... How do I do this

Thanks for your help in advance
Tom.

Hi,

Draw it yourself in paint event.

Private Sub Panel1_Paint(ByVal sender As Object, ByVal e As
System.Windows.Forms.PaintEventArgs) Handles Panel1.Paint
e.Graphics.DrawImage(Image.FromFile("C:\camera.bmp"),
Panel1.ClientRectangle)
End Sub

Check out the constructor for Bitmap. There is the following:

Initializes a new instance of the Bitmap class from the specified existing
image and with the specified size.
[Visual Basic] Public Sub New(Image, Integer, Integer)
[C#] public Bitmap(Image, int, int);

You can load your image and then create a new one to use with the new size.

Just draw the image in the Paint event..

panel1_Paint(object sender, PaintEventArgs e)
{
e.Graphics.DrawImage(TheImage,panel1.ClientRectangle,0,0,TheImage.Width,
TheImage.Height,GraphicsUnit.Pixel);

//draw your foreground stuff here...
}

The GDI+ FAQ also has articles on how to resample or resize images.
