The MapServer team announces the release of MapServer 5.0.
Perhaps the most important new feature in this release is support for
map rendering using the Anti-grain Geometry (AGG) graphics library
(www.antigrain.com). AGG brings high quality 2-D rendering capabilities
to MapServer that will allow users to create maps with vastly improved
cartographic quality. Equally important is that using AGG results in a
minimal reduction in performance. All symbology supported by the default
GD (www.libgd.org) graphics library are also supported using AGG. These features are aimed at bringing high-end cartography
to on-demand web mapping.
This new version also includes dozens of small bug fixes, enhancements
and performance improvements. Among the new features are: style and
label attribute attribute binding; lookup table-based raster color
correction; dynamic charting (pie and bar); explicit label prioritizing;
enhanced debugging and logging; dynamic allocation for layers, classes,
styles and symbols; improved memory management and garbage collection
for MapScript; numerous improvements to OGC specification support, and
lots more.
The source code release is available at the usual location on the MapServer site:
