io.imsave() problems with passing arguments to plugin "freeimage"

[Zachary Pincus]

Hi Siggi,

This functionality is not exposed by the imsave() apparatus, but can be accessed by the image writing functions in the plugin that imsave() calls.

A quick scan through the source code is likely to be the most helpful thing, regarding the available flags, etc:
https://github.com/scikits-image/scikits-image/blob/master/skimage/io/_plugins/freeimage_plugin.py

In particular, the freeimage_plugin.write() function, around which freeimage_plugin.imsave() is a thin wrapper, allows you to set various flags.
So:
import skimage.io._plugins.freeimage_plugin as fi
image = fi.read('/path/to/whatever')
fi.write(image, 'whatever.tif', fi.IO_FLAGS.TIFF_NONE)

I used the io.imsave() with the freeimage plugin but by default it writs a compressed TIFF file. The freeimage documentation provides Flags to use for different compressions or for a non compressed type (TIFF_NONE). Can someone tell me how to pass theses Flags to the plugin?
