| enum NodeShapes |
| GraphToEps<CoordsTraits<X> > coords | ( | const X & | x | ) | [inline] |
Sets the map of the node coordinates.
| x | must be a node map with dim2::Point<double> or dim2::Point<int> values. |
| GraphToEps<NodeSizesTraits<X> > nodeSizes | ( | const X & | x | ) | [inline] |
Sets the map of the node sizes.
| x | must be a node map with double (or convertible) values. |
| GraphToEps<NodeShapesTraits<X> > nodeShapes | ( | const X & | x | ) | [inline] |
Sets the map of the node shapes. The available shape values can be found in enum NodeShapes.
| x | must be a node map with int (or convertible) values. |
| GraphToEps<NodeTextsTraits<X> > nodeTexts | ( | const X & | x | ) | [inline] |
Sets the text printed on the nodes.
| x | must be a node map with type that can be pushed to a standard ostream. |
| GraphToEps<NodePsTextsTraits<X> > nodePsTexts | ( | const X & | x | ) | [inline] |
With this command it is possible to insert a verbatim PostScript block to the nodes. The PS current point will be moved to the center of the node before the PostScript block inserted.
Before and after the block a newline character is inserted so you don't have to bother with the separators.
| x | must be a node map with type that can be pushed to a standard ostream. |
| GraphToEps<ArcWidthsTraits<X> > arcWidths | ( | const X & | x | ) | [inline] |
Sets the map of the arc widths.
| x | must be an arc map with double (or convertible) values. |
| GraphToEps<NodeColorsTraits<X> > nodeColors | ( | const X & | x | ) | [inline] |
| GraphToEps<NodeTextColorsTraits<X> > nodeTextColors | ( | const X & | x | ) | [inline] |
| GraphToEps<ArcColorsTraits<X> > arcColors | ( | const X & | x | ) | [inline] |
| GraphToEps<T>& nodeScale | ( | double | d = .01 | ) | [inline] |
Sets a global scale factor for node sizes.
If nodeSizes() is not given, this function simply sets the node sizes to d. If nodeSizes() is given, but autoNodeScale() is not, then the node size given by nodeSizes() will be multiplied by the value d. If both nodeSizes() and autoNodeScale() are used, then the node sizes will be scaled in such a way that the greatest size will be equal to d.
| GraphToEps<T>& autoNodeScale | ( | bool | b = true | ) | [inline] |
Turns on/off the automatic node size scaling.
| GraphToEps<T>& absoluteNodeSizes | ( | bool | b = true | ) | [inline] |
Turns on/off the absolutematic node size scaling.
| GraphToEps<T>& preScale | ( | bool | b = true | ) | [inline] |
By default, graphToEps() rescales the whole image in order to avoid very big or very small bounding boxes.
This (p)rescaling can be turned off with this function.
| GraphToEps<T>& arcWidthScale | ( | double | d = .003 | ) | [inline] |
Sets a global scale factor for arc widths.
If arcWidths() is not given, this function simply sets the arc widths to d. If arcWidths() is given, but autoArcWidthScale() is not, then the arc withs given by arcWidths() will be multiplied by the value d. If both arcWidths() and autoArcWidthScale() are used, then the arc withs will be scaled in such a way that the greatest width will be equal to d.
| GraphToEps<T>& autoArcWidthScale | ( | bool | b = true | ) | [inline] |
Turns on/off the automatic arc width scaling.
| GraphToEps<T>& absoluteArcWidths | ( | bool | b = true | ) | [inline] |
Turns on/off the absolutematic arc width scaling.
| GraphToEps<T>& distantColorNodeTexts | ( | ) | [inline] |
Sets the color of the node texts to be as different from the node color as it is possible.
| GraphToEps<T>& distantBWNodeTexts | ( | ) | [inline] |
Sets the color of the node texts to be black or white according to which is more different from the node color.
| GraphToEps<T>& nodePsTextsPreamble | ( | const char * | str | ) | [inline] |
Gives a preamble block for node Postscript block.
| GraphToEps<T>& undirected | ( | bool | b = true | ) | [inline] |
Sets whether the graph is undirected.
This setting is the default for undirected graphs.
| GraphToEps<T>& directed | ( | bool | b = true | ) | [inline] |
Sets whether the graph is directed. Use it to show the edges as a pair of directed ones.
This setting is the default for digraphs.
| GraphToEps<T>& title | ( | const std::string & | t | ) | [inline] |
Sets the title of the generated image, namely it inserts a %Title: DSC field to the header of the EPS file.
| GraphToEps<T>& copyright | ( | const std::string & | t | ) | [inline] |
Sets the copyright statement of the generated image, namely it inserts a %Copyright: DSC field to the header of the EPS file.
| void run | ( | ) | [inline] |
Like other functions using named template parameters, this function calls the algorithm itself, i.e. in this case it draws the graph.
