Summary

AddFlow Suite for .NET by Lassalle Technologies

Create interactive flowcharts and workflow diagrams and include a set of graph drawing algorithms. AddFlow Suite for .NET includes AddFlow for .NET and LayoutFlow for .NET that is a collection of 5 layout components to enable you to automatically display graphs or flow charts following some aesthetic rules. Includes: HFlow (hierarchical layout), OFlow (orthogonal layout), SFlow (symmetric force directed layout), SPFlow (Series Parallel),TFlow (tree or radial layout). These controls are AddFlow for .NET extensions. Each of these controls allows performing a graph layout automatically, positioning its vertices (also called nodes) and edges (also called links) on a form containing an AddFlow control. Visual Studio 2005 (VS2005, VS 2005) and Visual Studio .NET 2008 compatible. Royalty free redistribution and many samples included for Visual Basic .NET (VB.NET) and C#.

AddFlow Suite for .NET includes both AddFlow for .NET and LayoutFlow for .NET

Following is a list of the main AddFlow for .NET and LayoutFlow for .NET features

AddFlow for .NET

General

Drawings can be made interactively or programmatically

Distinct shapes, styles, colors, font can be defined on a per item basis (for a node or a link) or as default properties for the control

Supportof several collections allowing you to traverse the graph in many ways

Many properties allowing customizing the control (CanDrawNode, CanMoveNode, CanMultiLink, etc...) or an item (XSizeable, YSizeable, XMoveable, YMoveable, Selectable, Stretchable, etc...)

Interactivity and display facilities

Multi selection

Multi-level Undo/Redo

Grid support

Nodes stay connected when moved or resized

Zooming

Scrolling, drag scrolling

Anti-aliasing

OwnerDraw property to provide custom drawing for an item or for the entire AddFlow control

Reflexive links

Rigid links

Hidden links

Possibility to interactively change the origin node or the destination node of a link

Automatic graph layout

AddFlow does not directly provide any automatic graph layout feature. However LayoutFlow, a set of 4 Graph layout components that can be added on:

HFlow for .NET (hierarchical layout)

OFlow for .NET (orthogonal layout)

SFlow for .NET (symmetric force directed layout)

TFlow for .NET (tree layout)

SPFlow (series Parallel)

Notices:

HFlow (hierarchical layout), OFlow (orthogonal layout), SFlow (symmetric force directed layout), SPFlow (Series Parallel),TFlow (tree or radial layout) are AddFlow extensions and you cannot use them without AddFlow.

You can purchase LayoutFlow separately or included in the AddFlow Suite license

LayoutFlow for .NET

LayoutFlow for .NET is a set of five graph layout .NET components:

1) HFlow

The HFlow layout algorithm arranges vertices in horizontal layers. The orders of the vertices are chosen so that the number of crossings is kept small. HFlow just produces a reasonable solution, not the optimum solution.

2) OFlow

The OFlow layout algorithm allows performing an orthogonal layout on a graph. The layout is orthogonal since it produces an orthogonal drawing where each edge is drawn as a polygonal chain of alternating horizontal and vertical segments. OFlow works with any graphs, connected or not. In the resulting drawing, if the graph is a graph of maximum degree four, then each node has the same size. If the degree of a node is higher than four, then the height of the node is expanded.

3) SFlow

The SFlow layout algorithm allows performing a symmetric layout on a graph. The symmetric layout produces a high degree of symmetry and is particularly useful for undirected graphs, where the directions of the edge are not important.

The resulting layout is often good. However it requires considerable computational resources and therefore should be used for small graphs (less than 300 nodes). Using the animation mode you can see how SFlow is working.

5) SPFlow

The SPFlow layout algorithm allows performing a series-parallel layout on a graph. The SP layout applies only to a specific subset of graphs: series-parallel digraph (more precisely, a set of series-parallel diagraphs). A series-parallel digraph is defined recursively as follows.

A digraph consisting of two nodes, a source s and a sink t joined by a single link is a series-parallel digraph.

If G1 and G2 are series-parallel digraphs, so are the digraphs constructed by each of the following operations:

- the parallel composition: identify the source of G1 with the source of G2 and the sink of G1 with the sink of G2.

- the series composition: identify the sink of G1 with the source of G2.

We use an algorithm that allows drawing series-parallel digraphs with as much symmetry as possible.

5) TFlow

The TFlow layout algorithm allows performing a tree layout on a graph. The tree layout applies only to a specific subset of graphs: rooted trees. In such a graph, no vertice may have more than one parent. The drawing of the tree occupies as little space as possible while satisfying certain aesthetics.

If the DrawingStyle property is "Layered":

vertices at the same level of the tree are placed on the same line

a parent is centered over its childs

If the DrawingStyle property is "Radial":

the root is placed at the origin

the layers are concentric circles centered at the origin

Notice that it is necessary to use AddFlow for .NET to be able to use LayoutFlow for .NET. Both products are installed via a common installation program.

What’s New in AddFlow for .NET V2.2?

Visual Studio 2008 compatible (VS 2008)

What’s New in AddFlow for .NET V2.1?

Enhancements

Substantial improvements have been introduced in the AddFlow for .NET serialization feature:

Four new events allowing the serialization (and de-serialization) of custom nodes and links (objectsof a class derived from the Node or the Link class)

The speed of the ReadXml and WriteXml methods is seriously improved

Additionally, the SendSelectionChangeEventproperty is introduced. (If it is false, the SelectionChange event is not fired

What’s New in AddFlow for .NET V2.1?

fully supports Visual Studio 2005 and .NET Framework 2.0.

a parent-child relationship that allows assigning labels to nodes and links, docking nodes inside nodes or offering a new and easy way to group nodes

support of the IXmlSerializable interface: WriteXml and ReadXml methods.

new events (Selection event, serialization events)

the option to use existing events programmatically

the property bag allowing to easily add new properties to nodes and links

enhancements in the undo/redo functionality which can be customized.

and other minor enhancements (like the possibility to draw the printer page limits in the diagram)

Create interactive flowcharts and workflow diagrams and include a set of graph drawing algorithms.
