New Features

What's new in Nevron Diagram for .NET 2012.1

• ThinWeb Diagram Control - a new AJAX-based web control that is completely HTML/JavaScript based. Comes with cross-browser support, simple integration with ASP.NET WebForms and MVC and a Model-View-Controller architecture. With this new control you can generate interactive image maps that can redirect the browser to a specified URL, handle client-side events, generate server-side and postback events, zoom, scroll and pan diagrams and more (available in Enterprise edition only).

What's new in Nevron Diagram for .NET 2011.1

• Layered graph layout - improved in terms of performance and compaction
• Flash export improvements - supports URL redirection through the interactivity style of the shapes
• AutoCAD export - the Diagram can now be exported in AutoCAD Drawing Interchange Format (DXF)
• Visio shapes import - users can import Visio XML stencils (*.vsx) in a Nevron library document and use the shapes in any Nevron Diagram
• Improved performance - the Diagram DOM model has been revised for performance. As a result you should see significant speed improvement when you edit diagram documents both from code and from the designer.

Features

Diagram Document Object Model

Drawing Document

Represents a diagram drawing. A drawing basically consists of shapes, residing in layers. Shapes can be linked to form complex graph relationships. Drawings can be automatically laid-out, visually edited and exported to various raster and vector formats (for example: BMP, PNG, SVG to name a few). Drawings can be printed.

Library Document

Represents a collection of reusable drawing clippings (masters), which you can drag and drop in the drawing document. Masters can contain one or more shapes and the connections between them.

Shapes and Groups

2D shapes

2D shapes represent boxes, containing vector or raster primitives and text. 2D shapes are also called simply shapes.

1D shapes

1D shapes represent lines with different geometry and behavior, which interconnect other shapes. 1D shapes are often called connectors.

Behavior Customisations

Protection

Protection helps you protect certain diagram element aspects from being changed or viewed by the user.
For example: you can protect shapes from being moved, resized, printed, exported to an image, deleted etc.

Interaction style

The interaction style defines the aspects of a shape, for which a view must create trackers (visual editors with handles), when the shape is selected.
For example: when a 2D shape is selected, the view will create trackers for its bounds, rotation angle and pin point. If you want to remove the rotation angle and pin point trackers, you just have to apply the desired interaction style to the shape.

Translation slaves

Translation slaves lets you specify the shapes, which are automatically translated when a certain shape is translated. This helps you build rigid structures.

Automatic Layouts

Obstacle Avoidance Routing

The obstacle avoidance routing of routable connectors addresses user laid-out diagrams in which certain connectors must be automatically rerouted not to cross any obstacles (shapes) in their path. Nevron Diagram for .NET provides support for both Mesh and Grid connectors routing, which is automatically performed. Addressed are issues like minimal bendings, port headings etc.

Tree Layouts

Nevron Diagram for .NET provides an extended set of automatic layouts, which deal with the shapes placement and connectors routing in the case of diagrams, representing trees. Implemented is the following set of tree layouts:

Layered Tree Layout

Layouts the tree vertices in layers. Supports breadth compaction. Produces both straight line and orthogonal tree drawings. Supports layout direction (top-to-bottom, left-to-right etc.)

Compact Depth Tree Layout

The depth arrangement of the vertices is as compact as possible. This layout supports breadth compaction. Produces both straight line and orthogonal tree drawings. Supports layout direction (top-to-bottom, left-to-right etc.)

Tip Over Tree Layout

Layouts the children vertices of a vertex in either a single row or a single column. The children placement can be specified on a per-vertex basis. Produces orthogonal tree drawings.

Balloon Tree Layout

Layouts the children vertices in a single circle around its parent vertex. The children angular range can be controller. Produces straight line tree drawings.

Graph Layouts

Nevron Diagram for .NET provides an extended set of automatic layouts, which deal with the shape placement and connector routing in the case of diagrams, representing graphs. Implemented is the following set of graph layouts:

Layered Graph Layout (Hierarchical Graph Layout)

This layout distributes vertices to layers. It tries to minimise the number of edge crossings and edge bends. Supports layout direction (top-to-bottom, left-to-right etc.). Produces polyline graph drawings.

Orthogonal Graph Layout

This layout tries to display the graph only with orthogonal edges and tries to minimise the drawing area, edge crossings and edge bends.

Symmetrical Graph Layout

This is a force directed layout, which aims to produce a straight line graph drawing with uniform edge lengths. It couples attractive and repulsive forces, which balance each other at user-specified desired edge length. Because of that the produced drawings tend to be symmetrical.

Spring Graph Layout

This is a force directed layout, which aims to produce a straight line graph drawing, which reflects the nature of the graph. It couples an electrical force (repels the vertices, which are close to each other) and a spring force (tries to enforce a certain distance between connected vertices). The parameters of the spring force can be specified on a per edge basis (e.g. some edges can be longer and/or stiffer than others).

Barycenter Graph Layout

This is a force directed layout, which splits the graph into fixed and free vertices. It places the fixed vertices at a strictly convex polygon and then places the free vertices at their barycenter (center of mass). This layout produces straight-line graph drawings.

Radial Graph Layout

This is a circular graph layout, which layouts the graph in concentric circles. Produces straight-line graph drawings.

Cells Layouts

Sometimes it is needed to arrange only the vertices of the graph. In these cases each vertex can be treated a cell. Nevron Diagram for .NET implements the following cells layouts:

Stack Layout

The stack layout represents a directed, constrained cells layout, which stacks the cells in horisontal or vertical order. Depending on the layout direction, the layout is constrained by either width or height.

Flow Layout

The flow layout represents a directed constrained cells layout, which arranges the cells in horisontal or vertical lanes. The flow layout does not preserve tabular metrics.

Table Layout

The table layout represents a directed constrained cells layout, which arranges cells in a tabular manner (e.g. preserves tabular metrics).

Dock Layout

The dock layout represents a space eating cells layout, which places vertices at per-vertex specified docking areas of the currently available layout area.
