[julia-users] Understanding how to display an Image and change pixels in real-time (fast)

[De Prins Maxime]

Hi,

*I can do this:*


using Base.Graphics 

using Cairo

using Tk



using Base.Graphics 

using Cairo

using Tk


win = Toplevel("Test", 800, 600)

c = Canvas(win)

pack(c, expand=true, fill="both")

ctx = getgc(c)

for x = 0:800

        for y = 0:600

               set_coords(ctx, x, y, 1, 1, 0, 1, 0, 1)

               set_source_rgb(ctx, x/800, y/600, 0)

               paint(ctx)

        end

end

reveal(c)

Tk.update()

But it is slow and not very nice.

Thanks
