Works too:
my @rgb = map {hex($_) } unpack 'xa2a2a2', "#FF00FF"; print "(",join(',',@rgb),")\n";

    While we're busy doing silly pack/unpack strings:
    $str = '#FE00FD'; $str =~ tr/0-9a-fA-F//cd; # remove non-hex characters my @rgb = unpack 'C*', pack 'H*', $str; # pack hex as 3 bytes, unpack + into list of 3 character codes $" = ","; $\ = "\n"; print "(@rgb)";
    Result:
    (254,0,253)

[choroba]: Corion a bug report?
[choroba]: I have no idea :-( I used to post to photobucket.com, but they don't seem to feature "private" pictures in the free version now
[Discipulus]: dazz i'm not an experts but i think it would be possible
[Corion]: dazz: I think Image::Magick can "read" from an in-memory filehandle
[Corion]: choroba: No, some general admin discussion of how to handle (company) user accounts
[Discipulus]: might be it is necessary to pass the pic data like MIME::Base64:: encode( data..
