I had the same problem with colorview
, what I did is to use colorim
instead.
See: http://stackoverflow.com/questions/25715909/export-a-uint8-array-as-an-image-using-images-in-julia
Ah yes, colorim
works. Regarding the other issue, does matshow
work with @manipulate
for you? i.e. does the image update when you move the manipulate slider?
The @manipulate
just does not work on my setup (I don't have any UI buttons)... So I'm reporting the results separately (without using @manipulate
)...
Author of Images here. I don't get the same crash with
using Images
d = zeros(10,10);
colorview(RGB, d, d, d)
(It just shows a black square, like it should.)
Can you please send the result of versioninfo()
and Pkg.status()
?
I had the same issue with matshow
, so I'm using pcolormesh
instead.
colorview
also crashes for me for that minimal working example. (Previous posts did not mention Colors
or ImageCore
, but the minimal example can't find colorview
or RGB
without them...?)
Pkg.add("Images")
Pkg.add("Colors")
Pkg.add("ImageCore")
Pkg.update()
d = zeros(10,10);
colorview(RGB, d, d, d)
using Images, Colors, ImageCore
versioninfo()
gives:

Everyone in the class needs to download this gist and then say
include("imagebranch.jl")
imagebranch("fixed-renaming")
More detail at https://github.com/timholy/Images.jl/issues/542#issuecomment-254059092, but this is the bottom line.
Oh, and just to make sure people know where to find docs: http://juliaimages.github.io/latest/
Please report issues to https://github.com/timholy/Images.jl/issues. Preferably each item as a separate issue. I'd view it as good thing if I get 15 bug reports or "this seems unnecessarily cumbersome" reports, as it's very hard as the author of software to know what other people find unintuitive.
@timholy I get this trying to run your script

@timholy trying your simple example with master ColorTypes fails with
Error encountered while saving "Nullable{String}()".
Fatal error:
UndefVarError: AxisArrays not defined
Gadfly's spy
mimics matshow
and works correctly with @manipulate
.
see: http://stackoverflow.com/questions/24598690/julia-plot-matrix-with-gadfly-jl
thanks ! finally something that works
workaround's are great but we should also fix the original problems
@musm, is your ColorTypes dirty? If so do git stash
and then try re-running imagebranch
.
I have a different guess now: it needed to fetch the latest first. I just updated that gist, see if it works better now.
If that fails, you can also try
cd(Pkg.dir("ColorTypes"))
;git checkout fixed-renaming
where the initial semicolon activates shell mode. If that fails for some reason, let me know the details.
@timholy thanks, things look like they are now working !
a number of students had issues https://github.com/alanedelman/18.337_2016/issues/12 and workarounds
by the way i think i had the wrong vcat on the svd should have it straight soon

I'm having a couple technical issues with Homework 4, wondering if anyone might have come across them.
1)
@manipulate
does not play nicely withmatshow
I cannot seem to make this work to "scroll through the images" as the homework instructs. When changing the manipulate slider, it just doesn't update the matshow image. What I'm trying, but doesn't work:2)
colorview
is crashing the kernel, every time I try to use it. The following minimal example, which should just show a black square, crashes the kernel:
