This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This module provides efficient functions for rendering vector graphics to a number of formats, including EPS, PostScript, and PDF. It provides an abstraction for multi-page documents, as well as a set of graphics primitives for page descriptions.

The graphics model is similar to that of the PostScript and PDF languages, but we only implement a subset of their functionality. Care has been taken that graphics rendering is done efficiently and as lazily as possible; documents are rendered "on the fly", without the need to store the whole document in memory.

The provided document description model consists of two separate layers of abstraction:

  • drawing is concerned with placing marks on a fixed surface, and takes place in the Draw monad;

  • document structure is concerned with a sequence of pages, their bounding boxes, and other meta-data. It takes place in the Document monad.

In principle, the functionality provided by EasyRender is similar to a subset of Cairo; however, EasyRender is lightweight and at least an order of magnitude faster.
