Oops! Concerning imread with png files, what I said about DOF was not accurate. A png image stored in matrix Awith 4 channels has size(A)(3) = 4 so one needs to "lock out" the 4th channel for imshow with something like imshow (A(:, :, 1:3))
This is just ignorance, but can imshow not produce an image with transparency? If not, is there a reason not? I'm imagining a case where I may want to change the background color of the axis before exporting a figure or similar.
Have a good day, Bill
