Cannot display free text annotation
I have some PDFs (generated by the Canvas LMS) which includes free text annotations like this:
<<
/Type /Annot
/Subtype /FreeText
/Contents (2 points)
/Rect [16.349998 432.03 65.65 445.83]
/CreationDate (D:20181001081439+00'00')
/M (D:20181001081439+00'00')
/Page 4
/NM (ffdfaae9-7753-4587-953d-ecb5aab27ccf)
/T (name of author)
/Subj (75420000000029087)
/Rotate 0
/DS (font: 12.6pt Lato; text-align: left; color: #EE0612;)
/BS 238 0 R
/CA 1.0
/F 128
>>However, I cannot see these annotations in Evince or Okular (both using poppler backend), not even in the annotations list.
Xpdf 4.0 can display these annotations in black color, and Adobe Acrobat Reader can show them correctly.
