A Generic error occurs at GDI+ at Bitmap.Save() after using SaveFileDialog

Question

I use the following code block with some more code inside the using block:

using (System.Drawing.Bitmap tempImg =
       (System.Drawing.Bitmap)tempObj.GetDa         


        

Answer 1

Dispose your bitMap object after save image:

 bitMap.Dispose()
 oimg.Dispose()

 bitMap = Nothing
 oimg = Nothing

Answer 2

Finally I could find what was wrong in my code and would like to mention it here as I think it may be useful to someone....

As I have given a relative path in tempImg.Save, and after the user clicks 'Save' in SaveFileDialog, the actual path for tempImg.Save become :

Path specified by SaveFileDialog + the relative path

automatically.

Thus if the path does not exist, this error occurs.

Thanks every one for the answers.

Answer 3

I also had once this problem- it happens because the bitmap locks and you can't save it( if you want I can find the exact explanation) so anyway a fix around is this: Create a new bitmap the size of the original bitmap you have- copy the original bitmap to the new created bitmap and then dispose the original bitmap and save the new one.

Bitmap bm3 = new Bitmap(bm2);

And then save.

Answer 4

I was facing the same issue, by changing image type ".bmp" to ".png" its work form me

Answer 5

Is this an ASP.NET application?

A Generic Error occured at GDI+ in asp.net mostly because of missing target folder / access permissions.

Also your code could be simplified to :

       using (Image image= dataObject.GetImage())
       {
            if (image != null)
            {
                image.Save("test.bmp");
            }
        }

This is code sample from Microsoft Forums.

// new image with transparent Alpha layer
using (var bitmap = new Bitmap(330, 18, PixelFormat.Format32bppArgb))
{
    using (var graphics = Graphics.FromImage(bitmap))
    {
        // add some anti-aliasing
        graphics.SmoothingMode = SmoothingMode.AntiAlias;

        using (var font = new Font("Arial", 14.0f, GraphicsUnit.Pixel))
        {
            using (var brush = new SolidBrush(Color.White))
            {
                // draw it
                graphics.DrawString(user.Email, font, brush, 0, 0);
            }
        }
    }

    // setup the response
    Response.Clear();
    Response.ContentType = "image/png";
    Response.BufferOutput = true;

    // write it to the output stream
    bitmap.Save(Response.OutputStream, ImageFormat.Png);
    Response.Flush();
}
