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. 
 
Regards, 
Praveena.
