[Bug ?] Annotations opacity is not taken into account when downloading the document

WebViewer Version: 8.5.0

Step to reproduces :

  • I create measurement annotations.
  • I programmatically change the FillColor of the annotation to add transparency : annot.FillColor = new Annotations.Color(r,g,b,0.8).
  • I download the pdf.
  • I open the pdf with another tool : the transparency has gone… (this is the problem…)

Am I missing something in the downloading config ?

Hi Antonie,

I’ve reproduced the behaviour you described. This is either due to a bug or our documentation not being up to date.
You can set the Opacity property specifically to let the annotation’s opacity to be effective in other applications.
