What I’m after is a Julia equivalent to Matlab’s “subplots”, that allows images to be displayed in arbitrary grids. I can “stitch” two images of the same size with

```
[img1 img2]

```

as the last line of an IJulia cell. But this shows the two images as one single, larger image, which is not what I want. I’m looking for something like

```
plot(img1, img2, layout=(1,2)) 

```

in which the sizes of the two images are irrelevant. The best I can find so far is

```
plot(plot(img1,seriestype=:image),plot(img2,seriestype=:image))

```

but this resizes the images so that they’re displayed with the same size. Again, that’s not quite what I want.

What’s my best option here?

Thanks,  
Alasdair

[MosaicViews.jl](https://github.com/JuliaArrays/MosaicViews.jl) provided a helper function `mosaic` for this feature. This package [is reexported by ImageCore](https://github.com/JuliaImages/ImageCore.jl/blob/d7c472211a9419b35525c6454fef56206426176d/src/ImageCore.jl#L8) so `using ImageCore` also gives you `mosaic`.

If [Gnuplot.jl](https://gcalderone.github.io/Gnuplot.jl/v1.4.1/) is an option, you may try:

```julia
using Gnuplot
img1 = randn(100, 200);
img2 = randn(150, 50);
@gp "set multiplot layout 1,2" "set autoscale fix" "set size ratio -1" :-
@gp :- 1 img1 "w image notit" 2 img2 "w image notit"

```

which would produce the following:

Many thanks - it does seem that mosaicview works well, especially if you use the `npad` and `fillvalue` options.
