如何在Julia中增强图像的RGB通道饱和度？

Question

目标：更改图像的色彩饱和度
代码：

using Images, ImageView;

function updateChannelSaturation(path::String, channel::Int, percentage::Float64)
    if isfile(path)
        img = load(path);  
        chnlView = channelview(img);
        cumPercentage = (100.0+percentage)/100.0;
        chnlView = permuteddimsview(chnlView, (2, 3,1));
        x = Int(size(img,2)/2):size(img,2);
        chnlView[;, x, channel] = min.(chnlView[;, x, channel] .* cumPercentage,1);
        imshow(img);
    else
        info("Error: Image Not Found!");
    end
end

function quit()
    print("Press q to quit!");
    while true
        opt = getChar();
        if opt == 'q'
            break
        else
            continue
        end
    end
end

#By Prof.Bogumił Kamiński
function getChar()
    ret = ccall(:jl_tty_set_mode, Int32, (Ptr{Cvoid},Int32), stdin.handle, true)
    ret == 0 || error("unable to switch to raw mode")
    c = read(stdin, Char)
    ccall(:jl_tty_set_mode, Int32, (Ptr{Cvoid},Int32), stdin.handle, false)
    c
end

updateChannelSaturation("/opt/julia/pictures/test.jpg", 1, 10.0);
quit();

错误：

no method matching permutedDimsArray(::typof(channelview), ::Tuple(Int64, Int64, Int64));

请帮助我解决问题！
