Bitmap questions

[Guest]

I don't like the following way to create a bitmap.
Bitmap bm = new Bitmap("C:\\MyBitmap.bmp");

Can I create a bitmap from the bitmap in a picturebox?

Thanks.

Several ways to create a bitmap (or any other image for that matter).

Image i = Image.FromFile("filename.jpg");
i.Save("filename.bmp");

The picturebox has a property called Image which is the internal image
class.

You can call the same methods on that to manipulate it.

You have to put the bitmap into the PictureBox to display it, why create
another one from it?

Perhaps you're thinking of doing something like:

Graphics g=myPictureBox.CreateGraphics();
g.DrawStuff
Bitmap b=myPictureBox.Image;

In which case you are labouring under a pile of misaprehension and should
probably go read the GDI+ FAQ.
