pdf annotation line and arrow

[camille_59]

Hi,

I'm using spire pdf to change the author of the annotations. I have 2 issues :
1 : It's working with PdfLineAnnotation, PdfTextAnnotationWidget, PdfSquareAnnotationWidget, PdfRubberStampAnnotationWidget, PdfPolyLineAnnotationWidget, PdfInkAnnotationWidget... but it seems like PdfLineAnnotation don't have Author attribute. So how could I change the author ?
2 : Is there a specifique class for "arrow" annontations ? I can't find it.

Thanks and best regards,

Hello,

Thanks for your inquiry.
1. Currently our Spire.PDF does not support modifying the author of "PdfLineAnnotation", I have logged the issue into our bug tracking system with the ticket number SPIREPDF-5095. Our development team will investigate and fix it. Once it is resolved, I will inform you in time. Sorry for the inconvenience caused.
2. We don't have a dedicated class for arrow annotations. I added the line annotation and the arrow annotation through Adobe and found that they are just different subjects. I have submitted the feature to add the line annotation subject to our development team. Once it is achieved in the future, I will inform you.

Sincerely,
