public int getMinimumArrayLength()
PixelIterator
When you call next(array) on this iterator, the array's length should at least be getMinimumArrayLength().
(Note the next() method is not in this interface: it exists in the subinterfaces: BytePixelIterator and IntPixelIterator.
You should not assume you know what this value is. For example: If an iterator is actually a 4-byte iterator that is reducing to a 3-byte format, then this value may be 4*getWidth() instead of the expected 3*getWidth(). Conversion and scaling is performed in the original array if possible to minimize overhead.

So in TYPE_4BYTE_ARGB this will be 4, but in TYPE_INT_ARGB this will be 1.
