Encryption in GetPageText?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm completely at a loss with GetPageText. When using it with the Parameter 2, I get - for example on page 1 of the "GettingStarted.pdf" document from Debenu itself - the firste line

250.53,715.64,#000000,12,"GBONLS+Verdana [Bold]","Delphi Edition"

which is fairly clear to me. When using the parameter 3, it is

"GBONLS+Verdana [Bold]",#000000,12,250.5258,128.7699,344.7498,128.7699,344.7498,114.1899,250.5258,114.1899,"'HOSKL (GLWLRQ"

so it seems that "Delphi Edition" is somehow (not very intelligently) encrypted to "'HOSKL (GLWLRQ".

Now I would be obliged if anyone could tell me why this is so and how the clear text could be retrieved. For my purposes parameter 3 is mandatory, because I need the bounds rectangle of the text as well as the text itself.

I'm using version 10.13

	jwinkl, Can you please send me the PDF file to support@debenu.com. Text extraction is complex and it looks like this PDF is using encoding tables. It is strange that Option 2 is working better than Option 3 as it is usually the other way around. Option 3 does a lot more work and can extract quite complex encoded fonts. Andrew.
