I have a problem viewing the background image of the flowchart in the website. The background image works fine in the Windows Form but not website.

Here is the code:



flowChart.DocExtents = new RectangleF(0, 0, 1000, 2500);

flowChart.BackgroundImageLayout = ImageLayout.Tile;

flowChart.BkgrImagePos = ImageAlign.Tile;

flowChart.BackgroundImage = "C:\test.png";



The background image showed in the website does not cover the whole flowchart (which has RectangleF width of 1000 and height of 2500).

When I change the RectangleF width and height become 800, the background image covers the whole flowchart.

Whenever I change the width and height of the RectangleF more than 800, the background image will only cover the top left 800x800 part.

Could you explain how to expand the background image based on the RectangleF width and height?

Thanks.
