Hi everyone,
I'm using iTextSharp for the first time this week and I have some
problems related to the following task:
I need a *C#* method to:
1- receive a file path, read the related PDF and,
OK.
2- set the "PDFXConformance" property,
Just setting the property isn't difficult.
Making sure the document passes a validation test: extremely difficult!
I don't know of any software that does this "automagically".
All the software I know requires human (manual) intervention:
- make decisions about colors,
- choose a substitution font,
- ...
3- Embed one new Font and
OK, that will work in some cases, but not always.
Embedding a font may require rewriting the complete content stream.
But it's no use making an assessment about the workload, because:
4-maintain the digital signatures that the PDF have.
That is impossible! Imagine a closed box that is sealed.
What you're asking is: I want to put some stuff in that box without a seal.
I count on your common sense to understand that this is impossible.
We're software developers, Gonçalo, NOT magicians.
