Hi,

I'm using identify to get width, height and size of a jpeg, I assume that
the size is always in the offset 6, but seems not the case, following are
two jpeg files, the sample2.jpg has an additional field '256c', what is a
reliable way to extract size of file from the output of identify?

sample1.jpg JPEG 320x400 320x400+0+0 8-bit DirectClass 60.2KB 0.000u
0:00.000
sample2.jpg JPEG 375x600 375x600+0+0 8-bit PseudoClass 256c 79KB 0.000u
0:00.000
