Review comment:
       Not sure if this is GitHub's UI issue, but looks like there are several spaces between
`IOException, ` and `ImageReadException`?

Review comment:
       This code here (`readImageData(final Rectangle subImage)`) looks a lot like the code
above for `readImageData(final ImageBuilder imageBuilder)`. Should we make a function to read
strips and re-use in both methods?

       Can we use the constant `TiffTagConstants.PLANAR_CONFIGURATION_VALUE_CHUNKY` (not sure
if the `1` here corresponds to that constant's value?)?
