Some shapes are stretched

Aspose.Diagram Product Family

Hello,
i have a mastershape consisting of several hundred shapes.
If i drop this mastershape out of the vssx-file to a page by visio everything looks good. Even when I insert this master shape into a page using Microsoft.Office.Interop.Visio, it looks fine.

But if i drop this mastershape to a page by aspose.diagram some of the containing shapes are shown streched out. I haven’t noticed this behaviour with any of my other master shapes.

To give you an example, I have stripped down the master shape so that only the problematic shapes remain.

I’ve attached my vssx-file. Can you tell me why the shape looks normal in Visio when I add it to the page, but looks stretched when using Aspose.Diagram?

Diagram diagram = new Diagram();
diagram.AddMaster("test_master.vssx", "test");

Aspose.Diagram.Master master = diagram.Masters.GetMasterByName("test");
Aspose.Diagram.Page newPage = new Aspose.Diagram.Page();
newPage.Name = "MasterTestPage";

int PageWidth = 210; //mm
int PageHeight = 297; //mm

DoubleValue PageWithMeasured = new DoubleValue(PageWidth, MeasureConst.MM);
DoubleValue PageHeightMeasured = new DoubleValue(PageHeight, MeasureConst.MM);

newPage.PageSheet.PageProps.PageWidth.Value = PageWithMeasured.Value; 
newPage.PageSheet.PageProps.PageHeight.Value = PageHeightMeasured.Value; 

newPage.PageSheet.PrintProps.PrintPageOrientation.Value = PrintPageOrientationValue.Portrait;
diagram.Pages.Add(newPage);

long shapeId = newPage.AddShape(0, 0, "test");

// Position the form centrally
Aspose.Diagram.Shape masterShape = newPage.Shapes.GetShape(shapeId);
masterShape.XForm.PinX.Value = newPage.PageSheet.PageProps.PageWidth.Value / 2;
masterShape.XForm.PinY.Value = newPage.PageSheet.PageProps.PageHeight.Value / 2;

diagram.Save("mastertest.vsdx", SaveFileFormat.Vsdx);

Hello,

Thank you for providing detailed information about your issue. It seems there might be a discrepancy between how Aspose.Diagram and Microsoft Visio handle the rendering of certain shapes.

Troubleshooting Steps

  1. Check Shape Data:
    Ensure that the shape data in your master shape is correctly configured. Sometimes, missing or incorrect shape data can cause rendering issues.

  2. Examine Shape Transformation:
    Double-check the transformation properties (XForm) of the shapes within your master shape. There might be a discrepancy in how Aspose.Diagram handles these properties compared to Visio.

  3. Review Master Shape Settings:
    Verify that the master shape settings, such as pins and controls, are correctly defined and do not have any anomalies.

Example Code Review

Here is a refined version of your code to ensure that it is correctly setting up the master shape and adding it to the page:

Diagram diagram = new Diagram();
diagram.AddMaster("test_master.vssx", "test");

Aspose.Diagram.Master master = diagram.Masters.GetMasterByName("test");
Aspose.Diagram.Page newPage = new Aspose.Diagram.Page();
newPage.Name = "MasterTestPage";

int pageWidth = 210; // mm
int pageHeight = 297; // mm

DoubleValue pageWidthMeasured = new DoubleValue(pageWidth, MeasureConst.MM);
DoubleValue pageHeightMeasured = new DoubleValue(pageHeight, MeasureConst.MM);

newPage.PageSheet.PageProps.PageWidth.Value = pageWidthMeasured.Value;
newPage.PageSheet.PageProps.PageHeight.Value = pageHeightMeasured.Value;

newPage.PageSheet.PrintProps.PrintPageOrientation.Value = PrintPageOrientationValue.Portrait;
diagram.Pages.Add(newPage);

long shapeId = newPage.AddShape(0, 0, "test");

// Position the form centrally
Aspose.Diagram.Shape masterShape = newPage.Shapes.GetShape(shapeId);
masterShape.XForm.PinX.Value = newPage.PageSheet.PageProps.PageWidth.Value / 2;
masterShape.XForm.PinY.Value = newPage.PageSheet.PageProps.PageHeight.Value / 2;

diagram.Save("mastertest.vsdx", SaveFileFormat.Vsdx);

Additional Resources

For further troubleshooting, you may refer to the following Aspose.Diagram documentation resources:

If the issue persists, please provide more details about the shape properties and any specific configurations that might be affecting the rendering. This will help us provide a more accurate solution.

This answer doesn’t help me.
What does the expert @philip.zhou say about this?

in meantime i’ve tested some things. I now know where the interface is causing the problem.

For example, with the shape named Endklemme.9988

In the shapesheet at Shape Transform at Height there is the formula:

=GUARD(IF(Actions.UK4.Checked,(9.5/7 mm),(5.2/7 mm)))

As far as I have tested, the interface has a problem with division. If I omit the division and enter the numbers directly, it works:

=GUARD(IF(Actions.UK4.Checked,(1.3571 mm),(0.7428 mm)))

However, I cannot adapt all my shapes to this phenomenon. That would be several thousand shapes.

Is there another way to solve the problem?

regards
Steve
