alpha minima >= maxima

[snibgo]

I don't know if this is a recent bug, or a very old feature from when IM wasn't sure if alpha meant transparency or opacity. If it is an old feature, perhaps it is too late to be "corrected".

Code: Select all

%IM%convert xc:rgba(0,0,0,0.2) xc:rgba(0,0,0,0.9) +append -format %%[fx:minima.a] info:
0.899992

%IM%convert xc:rgba(0,0,0,0.2) xc:rgba(0,0,0,0.9) +append -format %%[fx:maxima.a] info:
0.2

Tested in v6.9.1-6 on Windows 8.1.
