Gray fixed point number image arithmetic broken

[romainFr]

Maybe I'm missing something with the fixed point numbers change, but here is the symptom :

julia> using Images

julia> using TestImages

julia> test = testimage("mandril_gray")
Gray Image with:
  data: 512x512 Array{Gray{UfixedBase{Uint8,8}},2}
  properties:
    IMcs: Gray
    spatialorder:  x y
    pixelspacing:  1 1

julia> 2*test
ERROR: `.*` has no method matching .*(::Gray{UfixedBase{Uint8,8}}, ::Int64)
 in .* at array.jl:758
 in * at /home/romain/.julia/v0.3/Images/src/algorithms.jl:35

Sorry about that. Pkg.update() should fix it.

And the element-wise comparation is related with this?
I mean:

julia> img = TestImages.testimage("mandril_gray")
Gray Image with:
  data: 512x512 Array{Gray{UfixedBase{Uint8,8}},2}
  properties:
    IMcs: Gray
    spatialorder:  x y
    pixelspacing:  1 1

julia> mask =  img .< 37
ERROR: `isless` has no method matching isless(::Gray{UfixedBase{Uint8,8}}, ::Int64)

I'll add that too.

But you should read https://github.com/timholy/Images.jl#loading-your-first-image-how-images-are-represented and perhaps https://github.com/JeffBezanson/FixedPointNumbers.jl, and change that comparison to img .< 37/255. Still won't work until I add more methods, but at least it will be correct once I do.

I read and i like so much the new framework, great job ¡¡
yes works if:

mask =  img .< Images.Gray(37/255)

[timholy]

Ah, that was unexpected. Great. I'll leave this open and check related methods, though. Will probably be a couple of days, I need to prepare a talk...
