Preserve PDF copy protection when rendering to HTML
When rendering PDF files with protection against copying text and images to HTML, GroupDocs.Viewer adds an inert HTML attribute to the HTML <body> tag.
Use PdfOptions.DisableCopyProtection to turn off copy protection. When DisableCopyProtection is set to true, the inert HTML attribute won’t be added to the HTML <body> tag in any case.
Previous versions of GroupDocs.Viewer for .NET ignores PDF copy protection and does not add
inert HTML attribute to HTML <body> tag.This option is supported when rendering PDF files to HTML with embedded or external resources.
using (Viewer viewer = new Viewer("protected-resume.pdf"))
{
HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
viewOptions.PdfOptions.DisableCopyProtection = true;
viewer.View(viewOptions);
}
The following image shows the rendering of protected-resume.pdf with copy protection on the left and with with DisableCopyProtection option set to true on the right:
