PDF to PNG - SVG problem

Aspose.PDF Product Family
1

Hi,

I’m trialling Aspose.PDF for .NET and using the
PNGDevice to convert a multi-page PDF to PNG files. On some pages of
the PDF there are multiple SVG images, however only the first SVG image
on each page renders. Is this a bug, or do I need to do something
differently?

I can provide the PDF and PNG files if it helps.

Regards,
Andrew.

Hi Andrew,

Thanks for your interest in our products.

Can you please share the source PDF document and the resultant PNG image so that we can test the scenario at our end. We apologize for this inconvenience.

Hi,


I’ve attached an example PDF and output PNGs. Here’s the code I’m using.

Thanks,
Andrew.

public string ConvertToPNGs(Stream pdfFile, string outputFolder, int dpi)

{

var png = new PngDevice(new Resolution(dpi));

var pdfDocument = new Document(pdfFile);


var pageIndex = 0;

var outputId = Guid.NewGuid().ToString();

var baseFilename = string.Format("{0}\\{1}", outputFolder, outputId);


foreach (Page page in pdfDocument.Pages)

{

// Update the page number.

pageIndex++;


string filepath = string.Format("{0}-{1}.png", baseFilename, pageIndex);

png.Process(page, filepath);

}

return outputId;

}

How long does it typically take to get a fix through? Just wondering if I wait for it, or find another solution?

Cheers,
