Reading an image with an alpha channel such as
[im, map, alpha] =
imread("http://tiles.openseamap.org/seamark/12/2180/1240.png";);
Successfully executes while reading one without an alpha channel in the same
manner
[im, map, alpha] =
imread("http://a.tile.openstreetmap.org/12/2183/1242.png";);
return a "some elements undefined in return list" error. It successfully
completes if the alpha return value is omitted.
For matlab compatibility, the function should return successfully in both
cases. alpha will be an empty matrix if none is present.
