Drawing Images in GDI+ in VB.NET
In this article I will explain about drawing images in GDI+.
The Graphics class also provide functionality for drawing images, using DrawImage and DrawImageUnscaled.DrawImage draws an Image object with a specifies size, and DrawImageUnscaled draws an Image object without scaling it. The DrawImage method has many overloaded forms.
An application creates Image object by calling the Image class's static FromFile method, which takes a file name as an argument. After that you create the coordinates of a rectangle in which to draw the image and call DrawImage. Listing 3.23 draws an image on the surface with a size of ClientRectangle.
LISTING 3.23: Drawing an image
Public Class Form1
Private Sub Form1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
' Create an image from a file
Dim newImage As Image = Image.FromFile("dnWatcher.gif")
' Draw image
Catch ex As Exception
Figure 3.35 shows the output from Listing 3.23.
