question about determining the color of text

[Lowe, Wyan]

Hi,

I’d like to open a pdf, extract the text, but also determine the color of the text during extraction.

For example, if the pdf text is 1 page, and nicely column formatted (maybe 3 columns with whitespace in between), maybe the 1^st column is numbers, if the number is ‘green’, it has one meaning, but if it’s blue, a different meaning…etc…The 2^nd column & 3^rd columns the same thing –depending on the color of the text, the meaning is different

Thanks

That's not impossible, but iText doesn't offer this kind of functionality out of the box.
You'll have to study the classes in the com.itextpdf.text.pdf.parser package.

Look at how getTextRenderMode() works - something similar can be done for text color.  If you wind up enhancing the parser to include this, shoot me a patch file and I'll review and incorporate it into the code base.
