1.2 Analyses¶
1.2.1 Analysis¶
Is it a bug in the validating software? - no
1.3 Possible solutions¶
1.3.1 Remake with ImageMagick¶
1.3.1.1 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.
1.3.1.2 Effects¶
1.3.1.3 Justification¶
1.3.1.4 Execution example¶
ImageMagick: convert <input> <output>
