PNG/PDF output is not getting generated for visio document

Aspose.Diagram Product Family

Hello,

I am using aspose.diagram v6.7.0 to generate PNG and PDF outputs of the attached visio file. The output is not getting generated. An error comes while saving the diagram object.

Following code is used to generate the PNG output:

Diagram diagram = new Diagram("Space Planning.vst");
String pageName = "Floor Plan";
Page srcPage = diagram.getPages().getPage(pageName);
File outputFile = new File("output.png");
int imageFormat = SaveFileFormat.PNG;

int pageIndex = 0;
ImageSaveOptions options = new ImageSaveOptions(imageFormat);
options.setResolution(96);
for (Page page : (Iterable) diagram.getPages()) {
if (page.getID() == srcPage.getID()) {
options.setPageIndex(pageIndex);
options.setPageCount(1);
break;
}
pageIndex++;
}
diagram.save(outputFile.getAbsolutePath(), options);


Following code is used to generate the PDF output:

Diagram diagram = new Diagram("Space Planning.vst");
File outputFile = new File("output.pdf");
diagram.save(outputFile.getAbsolutePath(), SaveFileFormat.PDF);



Can you please analyse this issue.

Thanks,
Neha

Hi Neha,

Thank you for being patient. In reference to the ticket ID's DIAGRAMJAVA-50371 and DIAGRAMJAVA-50372, please download and use the latest Hotfix version: Aspose.Diagram for Java 6.8.1. Please also let us know how that goes on your side.

Hello,


Thanks for your reply.

I tried the latest Hotfix version- Aspose.Diagram 6.8.1. It fixes the issue of PNG and PDF output not getting generated. Although the output is getting generated now, but there is Data Loss in the output (both PNG and PDF). I have attached a screenshot of the issue for your reference.

I also generated SVG output of the same page, and because of wrong background color, a lot of data is not visible.

Can you please analyse this issue.

Thanks,
Neha

Hi,

Is there any update on following issues?

There is no progress on these issues since a long time. Currently we are using aspose.diagram v17.5.0 and the issues are unresolved in this version too. When can we expect a fix for these?
