Creating thumbnails with GDI+

=?iso-8859-1?Q?Andr=E9_Colbi=F6rnsen?=
-- Moved from [aspngfreeforall] to [ngfx-drawing] by James Avery <Click here to reveal e-mail address> --

In the VS.Net help, I have found a very interesting chapter re how to
create thumbnails. Problem is, the code is obviously written in C++ or
something and I have no clue how to translate this int VB.Net.

Here is the code from the example:

Image image(L"Compass.bmp");
Image* pThumbnail =3D image.GetThumbnailImage(100, 100, NULL, NULL);
graphics.DrawImage(pThumbnail, 10, 10,=20
pThumbnail->GetWidth(), pThumbnail->GetHeight());=20

Could anybody tell me where I could find some good gdi+ examples written
in VB.Net (or perhaps tell me how the above code should be written in
VB.Net)?

Tia

Andre,

    It looks like C# to me, assuming some weird character conversions from your
system.

    For a great bunch of System.Drawing articles (including thumbnailing), read
Chris Garrett's column at AspAlliance.com:
http://www.aspalliance.com/chrisg .

Cheers,

Peter

Actually, it looks like managed C++.
Calls to the CLR should be similar to other languages. Just ignore the *, -

try this:

Dim image = New Bitmap("compass.bmp")
Dim pThumbnail As Image = image.GetThumbnailImage(100, 100, Nothing, New IntPtr())

e.Graphics.DrawImage( pThumbnail, 0,10,pThumbnail.Width,pThumbnail.Height)
