Exception occurs when generating PNG of visio page

Hello,

I am using aspose.diagram v17.5.0 to generate PNG of page-'Page-2' of the attached visio file. Exception occurs when generating the PNG.

Following code is used to generate the PNG output:

Diagram diagram = new Diagram("test.vsdx");
String pageName = "Page-2";
Page srcPage = diagram.getPages().getPage(pageName);
File outputFile = new File("Page-2.png");
int imageFormat = SaveFileFormat.PNG;

int pageIndex = 1;
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);


Can you please analyse this issue.

Thanks,
Neha

Hi Neha,


Thank you for contacting support. We have tested your code in our environment, and it is showing a page index out of range error because you are setting the page index value as two. The page index starts from zero, since the right value is one. After setting the page index value to one, it shows a null pointer error. It has been logged under the ticket ID DIAGRAMJAVA-50505 in our bug tracking system. We have linked your post to this ticket and will keep you informed regarding any available updates. We are sorry for the inconvenience caused.

Hello,

I am using Aspose.Diagram v17.9.0 to verify this issue.
In the latest version, the output is getting generated but some MS SharePoint workflow items are rendered incorrectly.
