Hey Ralf 2009/10/21 Ralf Gommers <ralf.gommers@googlemail.com>:
Fixed in my asgrey branch: http://github.com/rgommers/scikits.image/tree/asgrey I sent Stefan a pull request but grab it there if you need it now.
If you only have grey-scale images setting as_grey to False should do the right thing as well.
Seeing the problem Holger reported makes me think that imread's behaviour is rather counter-intuitive. Should we not introduce a dtype flag, so that the outcome type is always as expected? I.e. imread('x.png') -> (uint8, uint8, uint8, ...) imread('x.png', flatten=True) -> uint8 imread('x.png', flatten=True, dtype=float) -> float imread('x.png', dtype=float) -> (float, float, float, ...) When it comes to dtypes, surprises are seldom good. What do you think? Cheers Stéfan
