Add line with curve joints in PDF using Aspose.PDF for .NET - Curves Joints are not smooth

Aspose.PDF Product Family
1

Hello,


I want to add a graph consisting of joint curves to existing pdf document.
Is it possible to do it using pdf Generator? If so, how can I create / open the generator on the existing pdf (please provide a short sample)?
I did’n find a way to accomplish it with the generator, so I used a regular Graph and Curve classes.
It works but the curves joints are not smooth. Aspose.Pdf.GraphInfo doesn’t have a LineJoinMode property but the Aspose.Pdf.Generator.GraphInfo has the property.
Could you recommend a solution?

Thanks,
Arkadi

Hi Arkadi,

Thanks for using our API’s.

Aspose.Pdf.Generator only offers the feature to create PDF files from scratch and I am afraid it does not support the feature to load existing PDF files. In order to fulfill your requirement, you may consider using new Document Object Model (DOM) of Aspose.Pdf namespace. Furthermore, you may also try using CreatePolygon(..), CreatePolyLine(..) methods of PdfContentEditor class.

[C#]

PdfContentEditor editor = new PdfContentEditor();
editor.BindPdf("example.pdf");

LineInfo lineInfo = new LineInfo();
lineInfo.VerticeCoordinate = new float[] { 0, 0, 100, 100, 100, 50 };
lineInfo.Visibility = true;
editor.CreatePolygon(lineInfo, 1, new System.Drawing.Rectangle(0, 0, 0, 0), "Welcome to Aspose");
editor.Save("example_out.pdf");

PdfContentEditor editor = new PdfContentEditor();
editor.BindPdf("example.pdf");

LineInfo lineInfo = new LineInfo();
lineInfo.VerticeCoordinate = new float[] { 0, 0, 100, 100, 100, 50 };
lineInfo.Visibility = true;
editor.CreatePolyLine(lineInfo, 1, new System.Drawing.Rectangle(0, 0, 0, 0), "Welcome to Aspose");
editor.Save("example_out.pdf");
