Tim: Thank you, that works great. Josef: I can plot 2D matrices with GR (which is what I want) but your code example doesn't work. GR looks pretty impressive, I'll have to check it out. A bit disappointed there's no interface to zoom in/out with the mouse and for some reason the window won'

And of course you can always plot an image as well: using Plots, TestImages plot(testimage("cameraman")) On Wed, Oct 26, 2016 at 11:04 AM, Josef Heinen wrote: > Using GR (for the image display) should be fast enough: > > using TestImages > using GR > > img = testimage("cameraman") > intensities

Using GR (for the image display) should be fast enough: using TestImages using GR img = testimage("cameraman") intensities = reshape(reshape(float(img.data[:]), 512, 512) for i in 1:10 tic(); imshow(intensities, colormap=GR.COLORMAP_GRAY); toc() end % julia img.jl elapsed time: 1.190862

Yes, it should be pretty responsive now---ImageView doesn't have to go through a Python layer, so I think it's a bit snappier. It's been a while since I've used Matlab, but at least when I first compared them ImageView was considerably better than Matlab for interactive display of movies, etc. But

Tim, when you say you fixed this, you mean the deprecation warnings? I'll definitely use the new version of Images. I haven't had a chance yet since posting this. Images and related libraries look great. The graphics functionality in Julia that deal with bitmaps like ImageView and pcolor in

Hmm, I fixed this on the images-next branch but forgot to fix it on master. Will be fixed in https://github.com/timholy/Images.jl/pull/564. If you're just getting started with Julia & Images, you might want to consider using the upcoming version of Images. See https://github.com/timholy/Images.jl/
