Bitmap.MakeTransparent OutOfMemoryException

[Jax]

Whenever I use this method I get out of memory exception, even when using tiny bitmaps (100X100)
Does anyone know why this is
From what I remember OutOfMemory Exception is a default for other exceptions, does anyone know what it might be
I am of course using try catch and finally blocks to ensure in cases of exceptions resources get released, I just can't understand why i'm always getting this exception

Help me people of the newsgroups, you're my only hope

Can you post code that demonstrates this? It seems to be working fine for
me.

It's as simple as:

(psuedo)
FileStream fs = new FileStream(@"c:\myImage.bmp", FileMode.Open);
Bitmap b = Bitmap.FromStream(fs);
try
{
Label theColour= new Label();
// client side script where the user clicks the image
int x = Convert.ToInt32(TextBox1.Text);
int y = Convert.ToInt32(TextBox2.Text);
theColour.BackColour = b.GetPixel(x,y);
b.MakeTransparent(theColour.BackColor); // Error here, OutOfMemoryException
b.SaveAs(fs, ImageFormat.Jpeg); // Occasionally error here, unspecified.
Image1.Url = "c:\myImage.Jpg";
}
catch(Exception ex)
{
Response.Write(ex.ToString());
}
finally
{
b.Dispose();
fs.Close();
}
