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

Is `1` the equivalent of
`TiffTagConstants.PLANAR_CONFIGURATION_VALUE_PLANAR`? If so, I think we should
use the constant?

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?

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