[NTG-context] JPEG images resolution and externalfigure size

Hi, When using the currently latest version of ConTeXt to include a JPEG image as in the MWE below, the resulting image size in the PDF is half the size when compared with earlier versions. \setupexternalfigures[location={local,global,default}] \starttext \externalfigure[hacker.jpg][scale=1000] \stoptext The actual width (in the PDF) of the hacker.jpg image is: - ConTeXt version 2016.12.28: approx. 44 mm - ConTeXt version 2016.07.01: approx. 88 mm The correct width would be 86.868 mm (513 pixel / 150 DPI * 25.4). Is there a factor 2 lost somewhere? Cheers, Christoph
