Hi,
I need to save shapes as image

Diagram diagram = new Diagram(“d:/sample.vsdx”);
int i = 0;
ImageSaveOptions options = new ImageSaveOptions(SaveFileFormat.PNG);

foreach (Shape shape in diagram.Pages[0].Shapes)
{
if (shape.Type.ToString() != “Shape” ||
(shape.Type.ToString() == “Shape” && shape.NameU.Length > 0 && !shape.NameU.Contains(“Dynamic connector”)))
{
shape.ToImage($“d:/var/shape{++i}.png”, options);
}
}
diagram.Save($“d:/var/diagram.png”, options);

But ToImage save incorrect images.
How can I get correct shape image with transparent background color?
I attached file with Diagram.Save result and Shape.ToImage results

@dmbk,

We managed to replicate the problem of incorrect rendering of shapes. It has been logged under the ticket ID DIAGRAMNET-51452 in our bug tracking system. We have linked your post to this ticket and will keep you informed regarding any available updates.

In reference to the transparency of shapes, you can set transparency from 0 to 1 (complete transparency) scale as follows:
C#

shape.Fill.FillForegndTrans.Value = 1;
shape.Fill.FillBkgndTrans.Value = 1;

Thank you. I will wait for the fix.
