public Bitmap ExportAsImage(int pageIndex, SizeF customSize, bool keepAspectRatio);
What is the unit of the customSize? it is pixels or points?
Thanks in advance
"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 = newPdfLoadedDocument("example.pdf");
