FW: Invisible links

[John Renfrew]

Some parts of this message have been removed. Learn more about Nabble's security policy.

Let me start again with the simple premise.

 

In Acrobat when you manually add a link to a document there is the option to have it visible rectangle  or invisible rectangle. Doing the latter greys out the choice to set attributes for line, anything else allows for change of colour or thickness… (PC or Mac)

 

I am trying to re-create the same behaviour in iText, a link which is an invisible, but active rectangle

 

Setting PdfAnnotation (FLAGS_HIDDEN) works on a mac, but not a PC – in that the link appears to not be there until you comment out that line (again it works on a mac)

Suggestion was that instead link.setMKBorder (null) would have the desired effect. Only it doesn’t appear to do anything. The link box is still drawn on screen….

 

Any other avenues to try??

No!   Color = NULL means NO COLOR.  If you want Black, then ask for Black.

Just tried that… Doesn’t do the thing I am after..

 

Surely setting the Color to null just makes it Black

I think what you want is to set the border & fill color to null rather than setting the entire annotation "hidden".  Hidden annotations (& fields) should not interact with the cursor at all.  Sounds more like a mac-acrobat bug than one on the PC.

 

link.setMKBorderColor( null );

link.setMKBackgroundColor( null );

Successfully got my stamper to put several lines of text in different colours at the bottom of a document each with a link to something different.

 

Had been testing it hard on a Mac, when I came to add it to the client solution which runs on PC the outputted PDF file had the link there, but the cursor insisted on being a text i-beam which meant that it could not be clicked. As soon as it was turned into a visible type (and therefore ugly) it became a well behaved link again.

 

Is this normal behaviour??? Or did I miss a trick???

 

fm_Font, fm_fileIn and fm_fileOut are passed variables…

Why would you set the annotation to FLAGS_HIDDEN,
when in fact you want FLAGS_INVISIBLE?
