Hi Tomer, 

 

Thank you for using Syncfusion Products. 

 

At present we do not support exporting pages of the PDF document as images with custom zoom factor using PDF viewer WPF. As a workaround please use the ExportAsImage method in PdfLoadedDocument by providing custom size for an image to export. 

 

Please find the code snippet for your reference. 

 

PdfLoadedDocument pdf = new PdfLoadedDocument("example.pdf"); 

SizeF s = pdf.Pages[0].Size; 

Bitmap image = pdf.ExportAsImage(0, new SizeF(s.Width * zoomfactor, s.Height * zoomfactor), true); 

image.Save("output.png"); 

 

We have also provided a sample below which exports the page as image with custom size for your reference.

Please let me know if you need any further assistance.
