-transparent-color  is ised to define the color used to represent
transparency in the GIF color table.  (It can be the same color as an
existing 'opaque' color without problems.

It is not using for PNG.

To remove transparency, set the -background color and  -flatten  the
image.

Alturnativally  set a -bordercolor and add a '0' width -border or -frame!
