Enable or disable external hyperlink support.
[read/write property] enableExternalHyperlinks([out, retval] VARIANT_BOOL *on) enableExternalHyperlinks([in] VARIANT_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 enableHyperlinks).

The default is enabled.

viewer.enableExternalHyperlinks = False
