Hi,
I'm using SaveToPng() method to save my diagram to file store. However even the simplest of drawings taking huge space in MB. I'm not sure if I did something wrong here, can you please advise?
Please find the sample code below

            SaveFileDialog saveFileDlg = new SaveFileDialog();
            saveFileDlg.DefaultFileName = "sample.png";
            if (saveFileDlg.ShowDialog() == true)
            {
                Stream fileStream = saveFileDlg.OpenFile();
                this.diagram.SaveToPng(fileStream);
                fileStream.Close();
            }

Thanks in advance.

Thanks for the reply.

I dont want to use any 3rd party tools, is there any other way of acheiving this?

I had a similar issue. and after trying a lot of code. I tried setting the bounds of the diagram to 0 like this  currentDiagram.Bounds = new Rect(0, 0, 0, 0); then saved the image  like the above code and then reset it back to the original bounds. I reduced my image side from 28 MB to 1.2 MB.

I hope this  helps...
