Ipelets

The Ipe distribution already includes a few Ipelets (such as Insert image and Align) that are essential for using Ipe. Here are other Ipelets that you may wish to install.

• GraphDrawing can automatically lay out a graph.

• IpePlots is an ipelet to plot functions and to create parametric plots. It comes with a manual.

• The Graph Ipelet helps when drawing graphs: you can move vertices (and edges will follow) or shorten edges (such that arrow heads touch vertex disks). (The vertex-moving ability is now already available in Ipe 7.2.5.)

• Ipelets providing access to many CGAL functions

• qvoronoi is an Ipelet to compute Voronoi diagrams, Order-2 and Order-3 Voronoi diagrams, Delaunay triangulations, and Furthest-point Voronoi diagrams.

• L1voronoi is an Ipelet to compute L1 (Manhattan) distance Voronoi diagram of point set.

• The GML Exporter exports a graph to gml format. This Ipelet handles graphs similar to the Graph Ipelet.

• Point matching and free space diagram (by Günter Rote)

• An ipelet for making linear gradients was posted on the mailing list

• Simplify is an Ipelet to remove points from a path while retaining the shape, for example to get a good approximate drawing of a hand-drawn path; it can also approximate paths by splines.

• ipe2tikz is an ipelet to export readable TikZ code from Ipe, taking advantage of the symbolic styling mechanisms available in both systems.

• tangentline is an ipelet to draw tangent line segments between ellipses, arcs, circles and markers.

• polyfillet is an ipelet to creates circular fillets in polylines or polygons

• quickstyles is an ipelet that lets you quickly define and select styles using hotkeys

• remove-empty-layers is an ipelet which removes all empty layers from the current page.

• embedding visualizer is an ipelet that can draw linear, circular and bipartite arrangements of graphs. In all three cases, it can calculate the number of crossings among all edges of the graphs and the sum of edge lengths.

• ipe-copytools implements 3 additional GUI tools to create linear patterns, circular patterns and patterns along paths.

• ipe-lassotool implements a lasso selection tool in Ipe

• ipe projections can make axonometric projections easy when creating simple 3D drawings

• The Ipelets for Convex Polygonal Geometry are a collection of tools for visualizing and computing polygonal geometry structures, including Minkowski sums, Macbeath regions, Funk/Hilbert balls, and more.

The following ipelets were made at least partially obsolete by new functionality in Ipe 7.2.5:

• The Decorator Ipelet lets you decorate your objects.

• The Pagenumbers Ipelet provides some page numbering features that are not covered by the built in page numbering mechanism of Ipe.
