[sane-devel] 16-bit colour in new GIMP

[Vopros]

Hello. Can anybody explain what do I need to do with XSane and
xscanimage to be able to scan in 16-bit directly from GIMP? xscanimage
can scan in 16 bit and save the images, unstable GIMP can work with
them, but it only sees the plugin transferring INT32 data. How do I make
them work together?
