Description

When retrieving the number of components in a jpeg image, class org.apache.pdfbox.pdmodel.graphics.image.JPEGFactory seems to retrieve the wrong metadata ("markerSequence/sos/@numScanComponents" instead of "markerSequence/sof/@numFrameComponents").

As a consequence, a wrong color space might be assigned to the image, preventing such image to be properly rendered in an PDF document.

Attached is a jpeg file whose color space will be wrongly determined (PDDeviceGray.INSTANCE instead of PDDeviceRGB.INSTANCE)
