Aspose.Pdf Save to xps - first page is entirely black

out.pdf (46.5 KB)

This function Opens a Pdf file and then Saves the content as an xps file:

    static void f2(string iFile, string oFile)
    {
        Aspose.Pdf.Document pdf = new Aspose.Pdf.Document(iFile);
        Aspose.Pdf.XpsSaveOptions xo = new Aspose.Pdf.XpsSaveOptions();
        pdf.Save(oFile, xo);
    }

When I call this function on the uploaded out.pdf file, the xps file produced has a first page which is entirely black. The pdf content simply contains empty spreadsheet boxes - nothing fancy at all.

This behaviour exists in aspose.pdf 19.4

If you open the XML file /Documents/1/Pages/1.fpage, it starts like this:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<FixedPage xmlns="http://schemas.microsoft.com/xps/2005/06" xmlns:x="http://schemas.microsoft.com/xps/2005/06/resourcedictionary-key" xml:lang="en-us" Width="793.333333333" Height="1121.333333333" Name="Page1">
    <Canvas RenderTransform="1.333333373,0,0,1.333333373,0,0">
	    <Canvas>
		    <Canvas Clip="F1 M0,841 L0,-0.890014648 L0,-0.890014648 L595.280029297,-0.890014648 L595.280029297,-0.890014648 L595.280029297,841 L595.280029297,841 L0,841 Z">
			    <Path RenderTransform="1,0,0,-1,0,841" Data="F1 M0,841.890014648 L0,0 L0,0 L595.280029297,0 L595.280029297,0 L595.280029297,841.890014648 L595.280029297,841.890014648 L0,841.890014648 Z">
				    <Path.Fill>
					    <SolidColorBrush Color="#FF000000" />
				    </Path.Fill>
			    </Path>   . . . 

The problem is that the Path is being Filled rather than Stroked. If you manually changed Path.Fill to Path.Stroke then the page is no longer solid black.

There’s a further problem with the content of the Path Data - it contains duplicate vertices. Here’s what it looks like with added line breaks:

F1 M0,841.890014648
L0,0
L0,0
L595.280029297,0
L595.280029297,0
L595.280029297,841.890014648
L595.280029297,841.890014648
L0,841.890014648 Z

The Canvas Clip path is malformed in the same way.
