Hello Akos, Rendering a map in GeoTools involves adding your layers to a MapContent object, linking this to a GTRenderer object (almost always an instance of StreamingRenderer), and then asking the renderer to draw into a Graphics2D object. Each layer has an associated Style object, created either from a SLD file or programmatically.
For on-screen display there are the (very basic) gt-swing and gt-swt widget modules. Alternatively, if you only need to render into an image you can just pass a graphics object created from your image to the renderer. Have a look at the GeoTools tutorials. The Map Style tutorial introduces the basics of creating Style objects from SLD or programmatically: http://docs.geotools.org/latest/userguide/tutorial/map/style.html Hope this helps, Michael On 26 October 2012 23:04, Ákos Maróy <[email protected]> wrote: > Hi, > > I wonder how easy would it be do programmatically render a map using > geotools? > > Basically I want to achieve the same kind of rendering as done by > geoserver, but for the whole area that my spacial data covers.
