AddRelativeLinkToLocalFileA
Annotations and hotspot links
Description
The trailing A denotes the ANSI (char) DLL entry point; the ActiveX/COM surface exposes only the Unicode form. Behaviour is identical to AddRelativeLinkToLocalFile and string arguments are interpreted using the current SetAnsiMode code page
Adds a clickable hotspot rectangle to the selected page which links using relative path to a local file.
The file doesn't have to exist when the PDF is created but should exist when the PDF is viewed for the link to work.
Use the SetAnnotBorderColor function to change the colour of the hotspot border.
