drawLine() not visible in PDF/PNG/HTML (JAVA 23.1)

Aspose.Diagram Product Family
1

Dear Aspose Team,

I logged a ticket towards the end of last year requesting the drawLine() and drawPolyLine() to be added to the Java API. Draw Line with multiple points (Java). Released in version 22.12

It is meeting my needs perfectly however the shapes/lines seem to be missing when exported to PDF/HTML and PNG from the Visio file.

Any assistance would be appreciated.

Thanks

Can you please provide the sample files for our reference so that we can test the scenario in our environment and address it accordingly?

Please see attached reference files.

Includes:

  • .vsdx visio file (Drawing-Export.vsdx)
  • .html file exported from visio file (ExportToHTML.html and ExportToHTML_files)
  • .pdf file exported from visio file (ExportToPDF.pdf)
  • .png file exported from visio file (ExportToPNG.png)
  • The custom stencil i have been using (Custom-Stencil.vssx)
  • The image I used for the shapes (Host-HostServer.png)

Code lines I have been using to generate the files:

DiagramSaveOptions options = new DiagramSaveOptions(SaveFileFormat.VSDX);
diagram.save(path, options);
diagram.save("./generated/ExportToHTML.html", SaveFileFormat.HTML);
diagram.save("./generated/ExportToPNG.png", SaveFileFormat.PNG);
diagram.save("./generated/ExportToPDF.pdf", SaveFileFormat.PDF);

page.drawLine(0,0,0,0,cpArray);
cpArray being all the points of the line (double [])

Dear Aspose Team

I downloaded the latest 23.2 .jar file but the issue still persists.

Could you please confirm if it is working in your environment or if I am doing it incorrectly?

Thanks

Please provide the code to generate the “Drawing-Export.vsdx” file, mainly for drawing lines and setting the color of the lines.
When calling ‘drawingline’, we will set the line to the basic style and the color of the line will be black.

Thanks.

Hi Aspose Team

Apologies for the delayed response, i was working on a different project until now.

Please see attached file with code.
The project is to export a json based drawing to visio/PDF/PNG/HTML
Aspose code.zip (8.3 KB)

As mentioned, the lines dont seem to appear on anything except the vsdx file.

I have also downloaded and tested on the 23.3 version.

createLine.txt -> The function to draw lines
wholeFile.txt -> The entire file for referance

We will fix this issue in next version 23.4.
We find that in the code, in one case, the line pattern is set to 2, please set the other cases to 1, so that the line can be drawn
if(lineDash != null) newLine.getLine().getLinePattern().setValue(2);
When using the version 23.4 released start of next month, please set the line pattern to 1.
Thanks.
