Signature image is lost after opening document in Word for MAC generated by Aspose.Words for Java

I am going to use documents digital signature from ASPOS, and I have some questions,

  1. Did I get right that ASPOSE supports digital signature(visible and invisible) only for 3 types
  2. I cloned aspose-words-examples from Github, and after signOptions.setSignatureLineImage
    the image doesn’t appear on the final signed document, why ?

It is to inform you that the issue which you are facing is actually not a bug in Aspose.Words. So, we have closed this issue (WORDSNET-20731) as ‘Not a Bug’.

This feature is not supported by Word for MAC. We cannot add a digital signature with the signature line by using the GUI of Word for MAC.

Created and signed with using of MS Word for Windows document shows the image and sign author correctly:
