Ipe is a drawing editor for creating figures in PDF format. It supports
making small figures for inclusion into LaTeX-documents as well as
making multi-page PDF presentations.
Ipe's main features are:
* Entry of text as LaTeX source code. This makes it easy to enter
mathematical expressions, and to reuse the LaTeX-macros of the main
document. In the display text is displayed as it will appear in the
figure.
* Produces pure PDF, including the text. Ipe converts the LaTeX-source
to PDF when the file is saved.
* It is easy to align objects with respect to each other (for instance,
to place a point on the intersection of two lines, or to draw a circle
through three given points) using various snapping modes.
* Users can provide ipelets (Ipe plug-ins) to add functionality to Ipe.
This way, Ipe can be extended for each task at hand.
