v7 alpha in txt:

[snibgo]

In v7.0.1-4, Windows 8.1, pre-built binary, the alpha value reported in "txt:" format (as the final comment) is always reported as zero. For example:

f:\web\im>magick xc:rgba(22%,33%,44%,0.3) txt:
# ImageMagick pixel enumeration: 1,1,65535,srgba

0,0: (14418,21627,28835,19661) #3852547B70A34CCD srgba(22%,33%,44%,0)
