does anybody know, can I retrieve by REST service in GeoServer an raster representation of layer? Just like in for ex. ArcGIS REST Api: when I send:

    MapServer/export?dpi=96&transparent=true&format=png8&bbox=338477.336%2C360036.34849999996%2C619993.648%2C548154.8615&bboxSR=2180&imageSR=2180&size=1064%2C711&f=image

in response I get png image of layer in defined bbox.

You have to use WMS GetMap, you should be able to find lots of examples
online (and you can download
the specification from the OGC web site, too)

Hi Krystian,
That should be possible with a standard WMS request. For example the following creates a PNG of our 1:50k OS raster:

http://wppgeog3:8082/geoserver/OS_Rasters/wms?service=WMS&version=1.1.0&request=GetMap&layers=OS_Rasters:50000_Colour&styles=&bbox=400000.0,220000.0,460000.0,320000.0&width=307&height=512&srs=EPSG:27700&format=image%2Fpng

thank you for quick replay.

Yes, i know I can do it via WMS interface, but this solution would need some
server-based coding for parsing XML response and so on... and my application
is pure JavaScript and I've just implemented REST API and just wondering how
to connect it to geoserver...

so if getting raster as response is not possible, so maybe somehow I can
request for geometry (coordinates) and get response in JSON format for ex.?

GeoServer does not implement the ESRI REST api, which unfortunately has
a incredibly poorly chosen name, as REST is a type of protocol.
It's like asking if GeoServer implements SOAP o HTTP api, but having in mind
a particular implementation of it.

The GeoServer REST Configuration API is meant for configuration only, and
has
been around longer than the ESRI one, but it does not do the same things,
it's the to allow the automation of config changes such as adding a layer,
changing a style and so on.

If you want GeoJSON you can get it via the WFS protocol, but we don't
support
the custom JSON format ESRI uses

That said, nothing prevents anyone from implementing the ESRI REST API
on top of GeoServer, or to build a json output format that's compatible with
the ESRI proprietary syntax, it's just a matter of putting the necessary
reosources
on the table. Nobody has done that so far afaik.
