There are two different kinds of annotations in PDFClerk Pro:
|Dynamic Annotations||Proper PDF annotations, as specified in the PDF file format.|
|Static Annotations||These often offer more flexibility at the cost of losing edit-ability in the final PDF document.|
Which kind of annotation to use depends on your needs. Some annotations do not have a counterpart of the other kind, but if they do, the matter is often one of whether it is important that the annotation remain editable in the final PDF document. If that is not an issue then using static annotations usually provides a more customisable object. In many cases which option to use is mood and will be a matter of personal preference.
When editing either type of annotations you can display a grid to
aid with object placement (
Tools > Grid > Show Grid). You can
also force objects to snap to grid lines when dragging them on a page
Tools > Grid > Snap To Grid).
