signpdf2

• This package is used to insert a signature image (png) into a pdf at a specified location using python.

• We use units instead of pixel. Units are pdf-standard units (1/72 inch).

• You may have your input files stored on your system or on cloud with a GET url to them.

  • Following example shows how you can insert a signature in a pdf (stored locally or available through a GET url)
  • Then save the signed pdf locally or make a PUT request to a PUT url

• Works for python 3.12

• pdf_utilities.py files is not used anywhere in this package. It's just provided as an accessory.

Example

"""
:param sign_w: signature width in units
:param sign_h: signature height in units
:param pdf_file:  name and path of pdf file on local system
:param signature_file: name and path of signature image file
:param page_num: page number of pdf to sign. Index starts at 0
:param offset_x: offset units horizontally from left
:param offset_y: offset units vertically from bottom
:param signature_expand: Original page dimension is expanded to
    accomodate signature if signature dimensions are more than original
:param signature_over: Signature is over or under the original pdf
:param sign_timestamp: Bool. If true, then add current timestamp below
    signature
