I have created a EMF for a page of the PDF document using PDFium. But the text rendered from the EMF on a canvas is not proper. I have attached the the text from the PDF document and part of the text available in the EMF in the attachments. The code snippet I have used is given below.

IntPtr pages = PdfiumViewer.FPDF_LoadPage(doc, pageIndex);

IntPtr dc = graphicss.GetHdc();

PdfiumNative.FPDF_RenderPage(dc, pages, 0, 0, Width, Height, 0, PdfiumNative.FPDF.PRINTING);

Can you please provide a solution to fix this?

It almost looks like a font issue? Doe you know if the font is embedded in the PDF or pulled from the system? I'm not sure how EMF gets access to fonts, if it uses ones provided or uses the system fonts.

Does "pdfium_test --emf input.pdf" generate an input.pdf.emf with the
same problem?
