Create large sparse images in Julia

Is it possible to create a large sparse image in Julia? Tim Holy's (excellent) Images.jl library looks like it is designed for full image matrices, where each defines each pixel.

I would like to make a bifurcation diagram which is rather meager. Ideally, I would like to make one poster size, but the corresponding full image matrix would be too large to generate.

Thank you for your time.

An Image can be created from any AbstractArray that includes a sparse matrix:

 julia> using Images julia> S = sprand(10^4, 10^4, 0.01); julia> img = grayim(S) Gray Images.Image with: data: 10000x10000 Base.SparseMatrix.SparseMatrixCSC{Float64,Int64} properties: colorspace: Gray spatialorder: xy

Now, what do you do with this image, determine how happy you are with this. But nothing prevents you from defining it.

UPDATE: images now treat any AbstractArray as an image, no more Images .
