Bug #98398 for Graph-Easy: Patch to handle color lists

Here is a patch to handle colorlists in GraphViz In Graph::Easy::Attributes sub _color { # Check that a given color name (like 'red'), or value (like '#ff0000') # or rgb(1,2,3) is valid. Used by valid_attribute(). # Note that for color names, the color scheme is not known here, so we # can only look if the color name is potentially possible. F.i. under # the Brewer scheme ylorrd9, '1' is a valid color name, while 'red' # would not. To resolve such conflicts, we will fallback to 'x11' # (the largest of the schemes) if the color name doesn't exist in # the current scheme. # Handle new colorlists -- colors separated by : my ($self, $org_color) = @_; $org_color = lc($org_color); # color names are case insensitive $org_color =~ s/\s//g; # remove spaces to unify format my $rc = 1; # Return code if the colors are ok foreach my $color ( split(':', $org_color) ) { if ($color =~ s/^(w3c|[a-z]+\d{0,2})\///) { my $scheme = $1; next if (exists $color_names->{$scheme}->{$color}); # if it didn't work, then fall back to x11 $scheme = 'x11'; next if (exists $color_names->{$scheme}->{$color}); } # scheme unknown, fall back to generic handling # red => red next if (exists $all_color_names->{$color}); # #ff0000 => #ff0000, rgb(1,2,3) => rgb(1,2,3) next if (defined $self->color_as_hex($color)); $rc = 0; # We couldn't find a matching color in any scheme } return $rc ? $org_color : undef; } Andrew Baumhauer | Network Architect | Interactive Data Corporation * 600 W.
