NiXPS View 3.0 features: XPS Notes
One of the exciting new features of NiXPS View v3.0 is the ability to add notes to an XPS document.
We invested a lot of time and in effort in this, as we were faced with a few challenges. Not the least the fact that the XPS specification doesn't have the annotations functionality built-in. Which either gave us the option to not implement it at all (like competitors do), or work around this limitation.
We feel that notes are a compelling addition to the to the XPS format, especially on Windows, where this brings XPS to a much higher, more usefull level. So technically we are working around the limitations of the XPS spec by putting the notes in the XPS content. This ensures that other, non-notes aware XPS Viewers show the notes information. In NiXPS View you can manipulate an delete the notes, in other viewers you merely view them. To counter the effect of not being able to move a note in a non-NiXPS Viewer, we made them transparent, allowing to see what the note covers (in NiXPS View you can hide the notes, or move it).
So in summary: NiXPS View allows you to annotate XPS files, and in such a way that they are visible in every XPS viewer too.
