1380in addition to the ones provided by X, where the additional A component
1381specifies opacity (alpha) values. The minimum value of C<0> is completely
1382transparent). You can also prefix any color with C<[a]>, where C<a> is on

1385You probably need to specify B<"-depth 32">, too, and have the luck that
