Post subject:  Memory leak while using XpsConverter.Convert to create pdf
Hi,

Below code is used to create a pdf file of 4 pages

var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open(lMemoryStream);
PdfSharp.Xps.XpsConverter.Convert(pdfXpsDoc, fileName, 0);

But it cause memory leak if call multiple times, say 100.

On analysis, it is found that the "table" member of type "Dictionary" in FontDescriptorStock class is holding the objects.

Could you please help?

Note: We are using 1.32 version. But, it does not contain PdfSharp.xps module. So, i copied the used the module from 1.31 version.

Font handling has been reworked for version 1.50. I don't know if the XPS code works with version 1.5x.

Unlikely that someone will investigate possible memory leaks of version 1.32 anymore.

Hi,

Thanks for the update.

Will I be able to save my xps document to pdf file using v1.50?

Also, v1.50 is mentioned as "beta" in sourceforge.net.

Thanks,
Vineeth

Will it be able to work below code with 1.50 version?

var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open(lMemoryStream);
PdfSharp.Xps.XpsConverter.Convert(pdfXpsDoc, fileName, 0);

OR
Do you have any recommendation to achieve my task using latest 1.50 version?
