Signature Block Positioning

In addition to a signature profile and the actual PDF payload the signature endpoints also take positioning data which determines where the signature block will be placed on the PDF document.

If no positioning data is given it will default to append the signature block after the content, either on the last page, or if there isn't enough space on the last page then on a newly added page at the end.

The position units are in "points" using the PDF coordinate system which starts in the bottom left corner of each page. The point unit can be converted to e.g. cm via the DPI, for example "1cm ~ 28.3465pt".

  • page - The page number where the signature block should be placed, starting with 1. A page number larger than the actual page count will append a new page instead. If omitted, the PDF-AS profile default is used. Without a profile default, PDF-AS automatically uses the last page or a new page if there isn't enough space.
  • x - Position of the signature's top left corner in points, from the left of the page. If omitted, the PDF-AS profile default is used. Without a profile default, PDF-AS centers the signature block horizontally.
  • y - Position of the signature's top left corner in points, from the bottom of the page. If omitted, the PDF-AS profile default is used. Without a profile default, PDF-AS places it right after the content on the selected page, or at the top if there is not enough free space.
  • width - Width of the signature block in points. If omitted, the PDF-AS profile default is used. Without a profile default, PDF-AS uses automatic width. Note that making it too small might break the internal layout.
  • rotation - Absolute rotation of the signature block in degrees, counterclockwise. If omitted, the PDF-AS profile default is used. Without a profile default, PDF-AS uses 0 degrees.

In case you don't want to have a visible signature block at all you can set invisible to true:

  • invisible - if true the block will not be visible. Defaults to false.
