[julia-users] Imread image conversion to Uint32 for use with Cairo

[Christopher Lee]

I am trying to load a JPG using imread.  The output is


RGB Image with:
  data: 5184x3456 Array{RGB{UfixedBase{Uint8,8}},2}
  properties:
    IMcs: sRGB
    spatialorder:  x y
    pixelspacing:  1 1)

Cairo expects images to be in Uint32 format.  I suspect that what I really 
want is to load an image in ARGB format and then reinterpret.  

I would think 
convert(Image{RGBA}, image)

would work but it doesn't.  

Also, how do I load in the image where x and y are reversed?
