Question

I need to visualize a large vector graphic. It’s a map of roads, the roads are just lines. Is there a library for that? It would be nice if that library had support for zoom-in/zoom-out and would be easy to extend. E.g. to implement selection of roads or some nice mouse-over effects. The licence should permit usage in a commercial project.

Thanks, Philip

Edit: Is there a reason not to go with Graphics2D or SWT Graphics? (The project is on SWT and doesn’t involve any SVGs.)

Answer 1

Have a look at Apache Batik

Batik is a Java-based toolkit for
applications or applets that want to
use images in the Scalable Vector
Graphics (SVG) format for various
purposes, such as display, generation
or manipulation. Another possibility
is to use Batik’s modules to convert
SVG to various formats, such as raster
images (JPEG, PNG or TIFF) or other
vector formats (EPS or PDF, the latter
two due to the transcoders provided by
Apache FOP). The latest revision of
Batik, release 1.7, is a conformant
static SVG implementation and supports
interactivity, linking and scripting
features of the SVG specification.

Another good alternatives are FreeHEP and VectorGraphics2D
