Hi, I am confused by the arrangement of multiple figures in a grid. I begin with the example code in the README,
gui = imshow_gui((300, 300), (2, 1)) # 2 columns, 1 row of images (each initially 300×300) canvases = gui["canvas"] imshow(canvases[1,1], testimage("lighthouse")) imshow(canvases[1,2], testimage("mandrill")) Gtk.showall(gui["window"])
it throws an error when accessing canvases[1,2]
canvases[1,2]
julia> imshow(canvases[1,2], testimage("mandrill")) ERROR: BoundsError: attempt to access 2×1 Array{Any,2} at index [1, 2]
and I check the size of canvases is
canvases
julia> size(canvases) (2, 1)
it seems that the canvases will arrange by column while the gui declares it should be by rows. The following two tries also support my guess.
If I change the indexes for accessing canvases
gui = imshow_gui((300, 300), (2, 1)) # 2 columns, 1 row of images (each initially 300×300) canvases = gui["canvas"] imshow(canvases[1,1], testimage("lighthouse")) imshow(canvases[2,1], testimage("mandrill")) Gtk.showall(gui["window"])
and if I exchange the grid size in imshow_gui
imshow_gui
gui = imshow_gui((300, 300), (2, 1)) canvases = gui["canvas"] imshow(canvases[1,1], testimage("lighthouse")) imshow(canvases[1,2], testimage("mandrill")) Gtk.showall(gui["window"])
But I have no idea what happens, my working environment is,
