Detect if a PDF is black and white or not in Java

Question

I have to print hundreds of single page PDF files and I wonder if I can detect if a PDF is black and white or color, I want to send black and white pdfs to a print queue and color ones to another.

I'm processing these pdfs in Java, can someone suggest me some technique?

Answer 1

I think you could give a try to PDFBox

In this example they extract an.icc (color profile) so may be what you are looking for.

How do you extract color profiles from a PDF file using pdfbox (or other open source Java lib)
