Hi Yang,

ImageJ has no image type consisting of 32-bit integer data, it
converts 32-bit ints to float when loading. Thus I fear that
you would have to write your own plugin for writing 32-bit ints.

If you can do with 16-bit ints (data range 0...65535), uncheck
"scale conversions" in Edit>Options>conversions and transform
to 16-bit before saving.
