Creates a file link annotation.
A file link annotation opens a file by using the application that is connected with the file extension (MIME type). Viewer applications maybe display a warning before the file is opened.

The file path can be defined as relative or absolute path. However, the usage of an absolute makes only sense if it can be guaranteed that the path exist on an arbitrary system.

If the coordinate system is bottom-up the point PosX, PosY defines the lower left corner of the bounding rectangle. If the coordinate system is top-down it defines the upper left corner.

The border of the link annotation is drawn by using the current line width, stroke color and line dash pattern. If the link should appear without a border set the line width to zero beforehand (with DynaPDF.SetLineWidth).

When clicking on a link annotation the rectangle is highlighted, that is a simple visual effect. Several highlight modes are supported, see DynaPDF.SetLinkHighlightMode for further information.
The function does not check whether the path is valid.

If the function succeeds the return value is an annotation handle, a value greater or equal zero. If the function fails it returns an error.

Use DynaPDF.WebLink for web links, DynaPDF.FileLink for file links, DynaPDF.PageLink or DynaPDF.PageLinkEx for page links and DynaPDF.FindText can help to find the location where to place the link.
