Exception in creating Bitmap

[Guest]

Dear all,
I have some codes as follows and it always return Exception even if the file
exists. I don't where is the error. Could you tell what wrongs about the
codes.
Also, how large of Image can be created in .Net Compact Framework. When I
have try to create a Image in 240 * 11000, it returns Out of Memory
Exception. However, the Pocket PC contains over 11M memory. How can I do?
Thanks.

***********************************************************
string imagePath = "001.jpg";
try
{
if ( System.IO.File.Exists(imagePath) )
{
Bitmap bmp = new Bitmap(imagePath);
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}

Result:
Exception
***********************************************************

When you create a Bitmap from a jpg file it is uncompressed in memory and
will require considerably more memory. Any particular reason why you want a
240 x 11000 pixel image? you are not going to be able to display the entire
image on screen at once.

Animation?

CE's memory management works differently than you think. Just becasue the
device has 11MB "free" doesn't mean you can make a heap allocation of 11MB.

And this is not even just heap allocation. The GDI heap is even more limited
