Q: We are working on a product which generates a flash file from a PDF
document when uploaded. Some of the pdf's contians "PBM pictures", is
there any way we could identify the PBM format pictures in the PDF
document using PDFTron PDFNet SDK (http://www.pdftron.com/pdfnet).
-----------
A: You can use PDFNet SDK to extract or decode any type of image
format that can be embedded in PDF (including JPEG2000, JBIG2,
DCTDecode, LZW, Flate, CCITT, etc). Please note that PDF documents
can't contain images in PBM format (unless they are embedded as file
attachments instead of page content).
As a starting point to familiarize yourself with PDFNet API you may
want to take a look at ImageExtract sample project (http://
www.pdftron.com/pdfnet/samplecode.html#ImageExtract).
