i've read the Perl::Magick docs online *again* because I need to do something I haven't done before: reduce the color space programmatically.

the client is uploading a handful ( 1 .. n ) PNG files. i can Get the colors using $obj->Get( 'colors' ), but in the documentation there's doesn't seem to be an analog for setting the same parameter ...

the online docs indicate that options that are "gettable" have analogs in convert ... but attempting to set the colors gives error 410, which is:

410 OptionError a command-line option was malformed
the code i've tried: 
my $err = $magick->Resize( height => 338, width => 450, colors => 128 
+);

[download]
and 
   my $err = $magick->Resize( height => 338, width => 450 );
   $err = $magick->Set( -colors => 128 );

[download]
both of which return the 410 error ...

can the number of colors be reset?
