Spool File Page Counter SDK – Wrong page analysis

Hi Guys,

We are evaluating the Spool File Page Counter SDK to analyse PDF files and during our testing we seem to have a page reported as BW when its actually colour.

The page in the PDF clearly has blue lines on it. Other colour pages in the document are correctly reported.

Any help would be appreciated, this appears to be a great solution for us but we do need accuracy as well as performance.

Thanks,
Customer

Thanks for your sample PDF file, we checked the blue lines in the page 3 in your PDF file, we noticed the line width for those blue lines are too thin, when we scale the page for color checking, those blue lines were disappear, this is the reason of the problem.

Please look at following screenshot, the width of blue lines on page 3 are very thin,
