 Thanks for the update, we have almost reached the point of success. Unfortunately there appears to be a problem with the MetaForm.mfGraph property that prevents you from drawing a GraphicsPath object. See the following two examples that illustrate the problem:

public string Works()
{
Form form = new Form();
form.Width = 500;
form.Height = 500;
form.Show();
MetaForm mf = new MetaForm(form, EmfType.EmfPlusDual, true);
mf.mfGraph.DrawRectangle(new Pen(Color.Black, 1), new Rectangle(100, 400, 50, 50));
mf.mfGraph.Dispose();
StringWriter st1 = new StringWriter();
mf.SplitingToStream(form.Handle, st1);
form.Close();
return st1.ToString();
}

public string DoesNotWork()
{
Form form = new Form();
form.Width = 500;
form.Height = 500;
form.Show();
MetaForm mf = new MetaForm(form, EmfType.EmfPlusDual, true);
GraphicsPath path = new GraphicsPath();
path.AddRectangle(new Rectangle(100, 400, 50, 50));
mf.mfGraph.DrawPath(new Pen(Color.Black, 1), path);
mf.mfGraph.Dispose();
StringWriter st1 = new StringWriter();
mf.SplitingToStream(form.Handle, st1);
form.Close();
return st1.ToString();
}

Thanks in advance.

Thank you for detailed post.
GraphicsPath object is still not implemented. It will be added in a day or two.

Thanks, I'm looking forward to the new release.

Also, can you please make sure that the MetaForm.mfGraph.Transform property works correctly since we make multiple changes to the Graphics.Transform during the process of drawing of our graphics. I think that there is something weird happening, but I will only know for sure once you have implemented the DrawPath() method.

Once again, thanks in advance.

DXF Export .NET processes MetaForm.mfGraph.Transform property. Linear Paths implemented (not published yet), we are working on round paths.

Thank you for posts!

There are two objects added to GraphicsPath:
- AddLine
- AddRectangle

At present we are working with ellipses.

I've been testing the Line and Rectangle GraphicsPath feature added yesterday in the DXF Export .NET; and i have some advices.

1. The GraphicsPath.StartFigure() doesn't seems to be working in the exporter, so, the exported GraphicsPath drawing is all conected!.
2. It's seems to be some kind of problems with the colours of the GrapicsPath, is that right?

THX.

PD: Hope this could help you!. When this feature is completely ready and working i'll be the first one to buy it!!!!!. How long do you think it's going to take to finish it?.

Pablo.

Hello all,
<blockquote id="quote">quote:<hr height="1" noshade id="quote">Originally posted by xander

Ok, I can replace the temporary invisible form with the ActiveForm, but how do I create the DXF string directly? You didn't really answer my question...

My question was: How can I convert mf.mfStream (in the above code) into a DXF string without using a temporary file? Or is that not possible?<hr height="1" noshade id="quote"></blockquote id="quote">
The problem has been solved. Corrected version of DXFExport.NET is available on: http://www.cadsofttools.com/download/dxfexportnet.zip
Feild DXFExport.current - contains created DXF file.
Please us the following construction:

Code: Select all

DXFExport vDXF;
...
//add your code
vDXF.Save();
//get access to the strings of DXF file in the memory
DXFExport.current - contains dxf file
