PDFsharp & MigraDoc Forum

Hello,

I am looking for a library to open a pdf file and get a list of all the operators with their parameters.
I understand that PdfSharp is for creating Pdf documents but I was wondering if there is a way do that with PdfSharp?

Thank you
Yannis

Hi, Yannis,

You can get a string containing all instructions and all parameters, but have to do the parsing yourself.
There is a third-party library that helps with text extraction, maybe that is a good starting point.
https://www.nuget.org/packages/PdfTextract/
It is GPL and I don't know where you can find the source code.

Thank you Thomas!
Do I have to build the string or can I get from PdfSharp?
Is it a class property?

I don't know. PdfTextract does it. Look how they do it.

ok
Thank you

I tried to use the code from the PdfExtract package to read text.
It works fine in many cases, but I have some PDFs where the output is weird.

The output from the attached PDF is the following:



I assume those are encoding problems.
I am a dummy if it comes to PDFs, some guidance on how I could extract the text correctly with PdfSharp would be helpful.

Thanks,
Alex

Had the same problem, https://www.nuget.org/packages/PdfSharpTextExtractor/ - this saved my time, it is a lib to extract a text from any pdf. It solves \u0003\0\u0004 problem too.
