New connection point

Hi, I found this issue: Create a new Connection Point
and I’m running link you provided at the bottom [just in case I also attached this source code]: https://docs.aspose.com/diagram/java/use-connection-indexes-to-connect-shapes/#UseConnectionindexestoconnectshapes-AddnewConnectionsontheshapeanduseConnectionindexestoconnectshapes
and the top shape is only connected with 1 bottom one and it still doesn’t look like that was the intended result.

Hi, I’m still getting the same behavior on 22.6 - 1 connection with top element and bottom middle element and 2 lines at the bottom left not connecting any shapes.


We have recorded your feedback and will investigate from this perspective. We will inform you once we have some updates.


Please try to use the code as per the updated documentation article. An output file generated by 22.6 version is also attached for your kind reference. 50974_out.zip (12.7 KB)

Ok, thanks, seems to be working. Btw. in these lines:

page.connectShapesViaConnectorIndex(shape1.getID(), 6, shape2.getID(), 3, connecter1Id);
page.connectShapesViaConnectorIndex(shape1.getID(), 1, shape3.getID(), 3, connecter2Id);

6 and 1 are IX’s of the Connection objects, right?


Yes, these are indices of (From) Shape.

Good day!

I use .NET and see the same strange behavior as described higher. Was not this bug resolved for .NET as well?

And one more question.

Connection connection1 = new Connection();
connection1.X.Ufe.F = "Width*0.33";
connection1.Y.Ufe.F = "Height*0";

In this snippet you show how to assign coordinates for the connection. But this principle is not clear for me and I can not find the description in the guides. The only thing I found is the connection class description in the reference guide.

Y - Specifies a y-coordinate on a shape in local coordinates. Local coordinates are those whose frame of reference is the shape, instead of the page.

Can you give me some example about how to assign coordinates in case when coordinates are placed directly as double and in case from your example (in the snippet below) when ufe property is used?

Thank you.


We are checking it and will get back to you shortly.

We apologize for any inconvenience caused.
Please try this sample code to set the index of connection and we will update the example asap:

        Connection connection1 = new Connection();
        connection1.X.Ufe.F = "Width*0.33";

//This indicates that the connection point is located at the bottom of this shape, one-third of the width.
connection1.X.Value = shape1.XForm.Width.Value * 0.33;
connection1.Y.Ufe.F = “Height*0”;
connection1.Y.Value = 0;

        Connection connection3 = new Connection();
        connection3.X.Ufe.F = "Width*0.66";
        connection3.X.Value = shape1.XForm.Width.Value *0.66;
        connection3.Y.Ufe.F = "Height*0";
        connection3.Y.Value = 0;

        connection1.IX = shape1.Connections.Add(connection1);
        connection3.IX = shape1.Connections.Add(connection3);
