    Description

      Converted a batch of tiffs to jpegs with Image Magick (6.9.2-6) "mogrify -format jpg *.tiff". QImageReader (Qt 5.5.0 desktop MSVC) fails to read them with the message "unable to read image data". Several other apps including Photoshop read these files OK.

      Sample jpeg attached.
