GDI+ Save Image

Hi,
I’m new to VB.NET
Q - How can I save an image drawn on picturebox ?

In VB 6 when we draw lines and shapes on picture box we used use Image property to get Image on the picture box

In .NET we have only one “Image” property instead of “picture” and “image” properties that will give only Background picture of Picture box not the Image on Picture box

I’ve tried this -- created an image and drew all the things on the image and finally set Picture box image property to this image, This causing problems that it is always erasing last image(I think certainly this is the wrong way)

I’m working on small designing application like paint

(sorry for my poor English)

Thanks in advance

Not really sure about your problem.

Maybe you want to save the images in an ImageList.?

So then you can refer back to previous images...

VB Code:

'create image container
Dim myList As new ImageList
 
'add current picturebox image to container list
myList.Images.Add(Me.picturebox1.Image)
 
'clear the current picturebox image from the picturebox
Picturebox1.Image = Nothing
 
Messagebox.Show("Abra Cadabra")
 
'set the image in the container to the picturebox
PictureBox1.Image = myList.Images(0)

well if I understand correctly, you have some things drawn in the picturebox and you want to draw some other things over that, right? if you want to do that, you can create an image from whatever you have in the picturebox, then draw on that image

I dont have VS.NET to test it right now, hope this works fine:

VB Code:

dim bmp as bitmap
 
' Originally the image property if set to nothing, when no picture is inside
if myPictureBox.image is nothing then
   bmp = new bitmap (myPictureBox.Width, myPictureBox.height)
else
   bmp = new bitmap (myPictureBox.image)
end if
 
dim gr as graphics = graphics.fromImage(bmp)
 
bmp.draw....
gr.dispose()  'hmm I'm not sure if this is really needed, someone tell me plz :D
 
myPictureBox.image = bmp

should work
