pdfEnableExternalHyperlinks
Enable or disable external hyperlink support.
void pdfEnableExternalHyperlinks(PDFViewerHandle viewer, BOOL on)
This setting allows disabling external hyperlinks, independent of
internal hyperlinks. Internal hyperlinks are defined as links to
locations within the same PDF file; external hyperlinks are links that
open another PDF file or that involve a URL.
This setting is ignored if all hyperlinks are disabled (see
pdfEnableHyperlinks).
The default is enabled.
