PdfHtmlTemplateShowInEvenPages Property

Specifies whether the template should be displayed on even-numbered pages of the PDF document. In HTML to PDF conversion, if ShowOnlyInHtmlToPdfPages is true, the first page generated from HTML is considered odd, the second even, and so on. If ShowOnlyInHtmlToPdfPages is false, the same rule applies based on the final document. In PDF merging or editing, this refers to even-numbered pages in the final PDF. The default value is true
