I have a PDF which was created in InDesign. When I open the PDF in Adobe Reader X for Mac and hover over certain parts of the document the cursor turns to crosshairs.
When I click in a region where the crosshair appears the whole region/feature gets selected in a blue bounding box, even if it is made up of several consituent words.
I have attached a screenshot below where the table Property/Particle is being selected. Could anybody tell me how this table is being detected by Reader
You should ask this question in the Adobe Acrobat forums where the Acrobat experts hang out.
But I can say that the regions will probably be more accurately delineated if you choose a PDF preset that includes Tagged PDF. When choosing File > Export > Adobe PDF (Print), this option is on the General panel. It will include structural information about the PDF.
