I’m having an issue where I’m creating a sound annotation but the speaker icon is not visible in Foxit PhantomPDF and Chrome. It is visible in Acrobat and the GcPDF web viewer.
In Foxit, I am able to hover over where it should be and the hand turns to a pointer, which I can then double click and it plays.
From this, I am assuming that the Speaker icon is not actually embedded in the PDF, but rather is viewer-dependent (i.e. the viewer application must have a “Speaker” icon in its library.) This is supported by the speaker icon looking different on Acrobat and the GcPDF web viewer.
So…I am wondering, is there a way I can embed a speaker image behind the sound annotation so that users with PDF viewers capable of playing sounds but not of displaying the Speaker icon can nevertheless still know that there’s a sound annotation there?
I’m thinking I’d use the Speaker icon from the GcPDF web viewer, which would simply be covered up by the annotation icon if the PDF is opened in the web viewer. If opened in Foxit, the clickable sound annotation would be transparent on top of this image.
What are your thoughts on this approach? If you think wise, is there an easy way to get the Speaker icon the web player uses besides hunting through the resources Chrome pulls down?
