Re: [julia-users] 3D image matrix
Hi André,
The output of `methos(view)` in both version are:
Julia version 0.3
julia> methods(view)

Julia version 0.4

And yes, it is version 0.3.2.
You're welcome,

I got it to work only if using is the last step before using `view`.
I can't think of a particular reason for it to happen. Although, in my

I finally got, as we can see in the attached file, thank you very much.

Re: [julia-users] 3D image matrix
hi Rivo,
Could you try to run this code (plot the image) in Julia 0.4.1?
What's the output of `methods(view)` in both versions 0.3.? and 0.4.1 (are
you sure it's Julia 0.3.2 or it'd be 0.3.8 instead)?
Thanks,
André.

ImageView.view(img) works also, thanks!
This is a Polarimetric SAR image from San Andreas Fault, CA.

Re: [julia-users] 3D image matrix
Yes, the third dimension is of size 3.
The `grayim` returns:
julia> img = grayim(pauliRGBeq)
Gray Image with:
data: 825x1000x3 Array{Float64,3}
properties:
colorspace: Gray
spatialorder: x y z
But `view` returns:
julia> view(img)
ERROR: `view` has no method matching
view(::Image{Float64,3,Array{Float64,3}})
This probably is relevant: The data is originally in gray scale, but we use
a decomposition to artifictiallty color it (Pauli Decomposition). The
function used to do it uses `reshape` to return the 3 Arrays together as
the same variable for the image:
pauliRGBeq = reshape([[A_Band],[B_Band],[C_Band]],(width,height,3))
And pauliRGBeq is the variable we want to view in a new window or plot in
order to select regions (that's the reason we need to either use mouse
events or mark it with a coordinate system to select)
Also, note that we are able to write it to a file using
imwrite(pauliRGBeq, "/home/folder/testimage.png")
Best,

Re: [julia-users] 3D image matrix
You can always say ImageView.view(img) if you need to scope the call. Perhaps
you're using another package that exports `view`.

[julia-users] 3D image matrix
Greetings,
I'm having trouble ploting a 3 dimentional matrix in Julia. The variable is
of the format Array{Float64,3}, and I need to visualize it in a window.
Using the Images.jl package
image = convert(Image, MyVariable)
RGB Image with:
data: WidthxHeightx3 Array{Float64,3}
properties:
timedim: 0
colorspace: RGB
colordim: 3
spatialorder: y x
pixelspacing: 1.0 1.0
And if I try to view it
view(image)
ERROR: `view` has no method matching
view(::Image{Float64,3,Array{Float64,3}})
I work with R and to view the same kind of images we use a function from a
discontinued package (the function is attached)
Question #1: What's the proper way to view this type of image.
Question #2: I need it to be ploted or viewed in a window that can handle
mouse iteractivity, how can I do it?
Regards
imagematrix.R
