About String Replacement

[David Lee <pe...@gmail.com>]

Hi,

I am very eager to implement the following code, but Tj or TJ returning
nothing, so the rest of the code is not working. I am using it with a very
simple pdf (attached).

https://svn.apache.org/repos/asf/pdfbox/tags/1.5.0/pdfbox/src/main/java/org/apache/pdfbox/examples/pdmodel/ReplaceString.java

I will be glad to know what's wrong.

Thanks.

Sam

I don't understand you: you mention you want to implement something that 
is already implemented, obviously since 1.5.0 at least (we're at version 
1.8.9 now).
What exactly is happening? "Tj or TJ returning nothing" doesn't make 
sense, these are PDF operators, they don't return anything.

Maybe you meant that you wanted to run that sample...

The good news is that because your post landed in moderation, the 
moderators (one of which is me) have a copy of the PDF (it isn't in the 
mailing list). The arguments of TJ are not human readable, because a 
font subset is used, i.e. this isn't pure ascii, only codes 1-21 are used.

So how can we help?

What version of PDFbox are you using? We removed that functionality in 2.0 because it was fundamentally broken. The code you link to is still available in PDFBox 1.8.x, but it doesn’t work properly - if you’re lucky it will work on simple PDF files.
