What I’m trying to achieve is to determine if the Postscript that I’m parsing contains any element that resides in a table (box).
Im asking whether if it had a built-in way to lay out tabular data on the page. My guess is that postscript doesnt have a concept of a table, cos I couldnt find it anywhere in the spec.
The problem that i need to solve is, I need to find a way to know if certain postscript lies inside a table.
Sounds like you are trying to draw something and test if any part of draws within some specified box. You can create a path for the thing to be tested (just don’t stroke or fill it), and create another path for the box (e.g. a table cell). Leave these two paths on the stack, and use one of the operators inufill, inustroke, etc.
If you happen to have the Postscript Language Reference 3rd edition, the goodies are listed under ‘Insideness-Testing Operators’ on p. 520, with details in the alphabetical section following that.
