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.
