Hello,
I have a question about pdf-text extraction and layers. I have
Pdf-files that have multiple layers. Only one of these layers is
containing text that I am interested in. Is there a way to extract
text from this particular layer only? I am familiar with programming,
so I just wish to know if API has support for this? So far, I have
been able to find only examples to add new layers for Pdf -files.
When you download iText from SourceForge, there's a zip with three jars.
The code you need is in the xtra jar: com.itextpdf.text.pdf.ocg.OCGRemover
With this class, you can remove layers from a PDF, keeping only the one
you're interested in.
Or, by using OCGParser correctly, you could filter our content of one
specific layer.
