[GitHub] [pdfbox] matejriseksc opened a new pull request #110: Fix the retrieval of number of components for a JPEG image
matejriseksc opened a new pull request #110:
URL: https://github.com/apache/pdfbox/pull/110
According to https://docs.oracle.com/javase/8/docs/api/javax/imageio/metadata/doc-files/jpeg_metadata.html the number of image components should be read from the markerSequence/sof/@numFrameComponents if you want to retrieve the number of the whole image.
At the moment the number is being read from the first `Start Of Scan marker segment` (sos) xPath encounters which in our case lead to the wrong classification of an image as a Grayscale instead of RGB resulting in a blank image added to the final PDF document.

Can you share this image? The oracle text is hard to understand. But I looked into the source code of twelvemonkeys, this confirms what you wrote.
