# The DOT_GRAPH_MAX_NODES tag can be used to set the maximum number of

# visualized by representing a node as a red box. Note that doxygen if the 

# number of direct children of the root node in a graph is already larger than 

# DOT_GRAPH_MAX_NODES then the graph will not be shown at all. Also note 

# that the size of a graph can be further restricted by MAX_DOT_GRAPH_DEPTH.

# The MAX_DOT_GRAPH_DEPTH tag can be used to set the maximum depth of the 

# graphs generated by dot. A depth value of 3 means that only nodes reachable 

# from the root by following a path via at most 3 edges will be shown. Nodes 

# that lay further from the root node will be omitted. Note that setting this 

# option to 1 or 2 may greatly reduce the computation time needed for large

# DOT_GRAPH_MAX_NODES. Using a depth of 0 means no depth restriction.

# a graph (i.e. they become hard to read).

DOT_TRANSPARENT        = YES

# Set the DOT_MULTI_TARGETS tag to YES allow dot to generate multiple output 

# files in one run (i.e. multiple -o and -T options on the command line). This

# support this, this feature is disabled by default.
