See IM Examples on Shadows
http://imagemagick.org/Usage/convolve/#shadow
But from the command line given I see you have done that.
An example image may also have been useful so I can see what is happening.
The first command is as described. no problem.
Second command.... Hmm yes this is clearly wrong. the hard shadow was clipped.
Looks as if you have found some bug.
Checking the result from the -shadow operator
As such the problem must be with the new -layers merge operator. The combined image is expanded horizontally correctly, just not vertically. Checking code...
Found the fault, correcting. The next IM point release (6.3.7-2) should have the fix. Thanks. Good spotting.

The result is the right size and offset, The canvas size is also a reasonable setting, as it can not accommodate a negative offset.rose: ROSE 70x46 66x51-4+5 DirectClass 16-bit
