I’ve been trying to go from a plot to a matrix of rgb values for a while now and the best solution I could come up with makes use of saving the plot as png and then loading it as an image. This is of course a very dirty workaround so I’m wondering if there is a more neat, direct way to do this? Her…

FWIW, this seems to do the same thing but avoids saving a file to disk: using FileIO, Plots; gr() p = plot(sin) io_buf = IOBuffer() show(io_buf, MIME("image/png"), p) # io_buf.data myImage = load(io_buf) # Array{RGB{N0f8},2} with eltype RGB{N0f8} plot(myImage, axis=nothing)
