i need to save the changes i make to an image, using the System.Drawing.Graphics
The problem is that, when i use the .save method of the image, the changes that i made are not saved to the file, only the original image, without any modifications.
I've tried several approaches, but none of them worked. The following code is the one i'm trying to use.
Private Sub bttExescutar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bttExecutar.Click
Dim gr As Graphics = picImagem.CreateGraphics()
Dim img As Image = picImagem.Image
gr.DrawImage(img, 0, 0)
Can you help?
My thanks in advanced
