Incorrect symbols appear in PNG output of visio page

Aspose.Diagram Product Family

Hello,

I am using aspose.diagram v6.7.0 to generate PNG of page - 'symbols' of the attached visio file. In the PNG output, symbols used in visio page are incorrect.

Following code is used to generate the PNG output:

Diagram diagram = new Diagram("field symbols.vsdx");
String pageName = "symbols";
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);


Can you please analyse this issue.

Thanks,
Neha

Hello,


Thanks for your reply.

I tried the latest Hotfix version - Aspose.Diagram 6.8.1. It fixes the issue for PNG output but now the same issue occurs for SVG output for the same Visio file. I have attached the SVG output for your reference.

Can you please analyse this?

Thanks,

Hi Neha,


Thank you for the inquiry. We have tested your Visio diagram “field symbols.vsdx” against the latest version 6.8.1 and sample code:

[Java]
// load a Visio diagram
Diagram diagram = new Diagram(“C:\AD\test745\field symbols.vsdx”);
// save in the SVG format
SVGSaveOptions options = new SVGSaveOptions();
options.setPageIndex(1);
diagram.save(“C:\AD\test745\Output_Java.svg”, options);

We have attached the resulting SVG for your kind reference. It works and does not change the said symbol as shown in your comparison screenshot "comparison.png. Please make sure that you have tested against latest Hotfix version 6.8.1, otherwise please provide us your sample code and environment details (Java version, IDE etc.). We'll investigate and reply you appropriately.

Hello,


Thanks for the reply.

When I opened the SVG file that you have shared in Internet Explorer, the symbols were correct, but when I opened it in Chrome and Firefox, the symbols were incorrect (As shown in the comparison screenshot “comparison.png” that I had shared earlier). The output should be same irrespective of the browser. So, can you please look into this issue further.

Thanks,
Neha

Hello,


Thanks for your reply.

I verified this issue for both PNG and SVG using aspose.diagram 17.1.0. Earlier incorrect symbol was coming, but now the symbol is invisible in both png and svg.

In SVG, the symbol is coming but in white color, so it is invisible as the background is also white. May be it is invisible in PNG for this same reason. Actual color of the symbol is blue so it should appear in blue color.

I have attached both png and svg outputs for your reference.

Can you please analyse this?

Thanks,
Neha
