Remake with ImageMagick
=======================

Suggestion
~~~~~~~~~~

If the bits are not completely missing, use ImageMagick. If the bits are missing JHOVE reports 'Expected marker byte 255 ' from JPEG-HUL and in that case 4 bytes can be added starting from position 7 in the file. Otherwise, the file more thoroughly corrupted.

Effects
~~~~~~~



Justification
~~~~~~~~~~~~~



Execution example
~~~~~~~~~~~~~~~~~

	ImageMagick: convert <input> <output>
