Hello All,

I want to know if there is any way to set the "Language" property of Reader Options. Please see the screenshot below to know the property that I'm talking about. Setting this property seems to be necessary to enable "Read Loud" feature of Adobe Reader 10+.

Waiting for your reply...

Cheers,

\r

Hi Ross,

most of the pdf document is real ascii content.

You can read/see and set this property without any library help directly into the pdf-code:

 1 0 obj
   << /Type /Catalog
      ...
      /Lang (en-US)
      ...
   >> 
 endobj

Cheers and welcome here,

Ingo

Hi,

Sorry for the delay in reply. I was away from my work desk.

Your answer sounds interesting and I opened the PDF files in Hex Editor to find the code that you're talking about. I found it in some PDF files whilst plenty of PDF files were not having any traces of "/Catalog". Not sure why, probably the PDF version is the factor here. However, if I look at the problem in view of this, it seems I cannot depend on this method. Also, I am not sure at which Hex address exactly to look for Lang code in PDF binary.

Any other method you can think of?

Waiting for your reply...

Cheers,
