Issue when merging xfdf string in pdf with FreeTextAnnotations applied

Technical Support Apryse SDK

Product: PDFTronSDK for .Net

Product Version: 7.0.1

I have the xfdf string that is generated from webviewer javascript. In Xfdf string, it has three anotations:

  1. FreeTextAnnotation : Fillcolor:‘#000000’, TextColor: ‘#FFFFFF’, Content:‘Redacted’
  2. FreeTextAnnotation : Fillcolor:‘#FFFFFF’, TextColor: ‘#000000’, Content:‘Redacted’
  3. FreeTextAnnotation : Fillcolor:‘#FFFF00’, TextColor: ‘#000000’, Content:‘’, Opacity:0.5

But when merged the xfdf in the pdf, it shows the text but the Fillcolor and TextColor is not as we have defined in xfdf string.

Code I used to merge the xfdf in pdf is:

Hello,

Sorry but it is difficult to read the XFDF that you have posted and copying it seems to report an invalid format. Could you please provide only the XFDF in an XML file as well as the document you are testing with?

Based on what I can see though, I do see appearances in the XFDF and that might be what is causing annotations to look a certain way. Could you try merging without appearances?

Also, have you tried using the latest WebViewer?
