C++ (Cpp) ClusterGraphAttributes::strokeColor Examples

Example #1

File: GraphIO_dot.cpp Project: marvin2k/ogdf

static inline void writeAttributes(
	std::ostream &out, const int &depth,
	const ClusterGraphAttributes &CA, const cluster &c)
{
	GraphIO::indent(out, depth) << "color=\"" << CA.strokeColor(c) << "\"\n";
	GraphIO::indent(out, depth) << "bgcolor=\"" << CA.fillColor(c) << "\"\n";
	GraphIO::indent(out, depth) << "label=\"" << CA.label(c) << "\"\n";

	// There is no point in exporting rest of the cluster attributes, so to
	// maintain high readability they are omitted.
