I had the same problem and ended up crafting a WMS GetMap request based on
the bounding box retreived via REST, with a proportional size, e.g.
GET /geoserver/rest/workspaces/myworkspace/featuretypes/mylayer.json
"""
'latLonBoundingBox': {u'crs': u'EPSG:4326',
u'maxx': 129.00192885,
u'maxy': -10.4123898666667,
u'minx': 96.8168171166666,
u'miny': -35.1899382666667},
"""
then create url like:
GET
/geoserver/myworkspace/wms?STYLES=&LAYERS=mylayer&SERVICE=WMS&FORMAT=image/png&MAXFEATURES=100000&REQUEST=GETMAP&SRS=EPSG:4326&HEIGHT=395&WIDTH=800&VERSION=1.1.1&BBOX=96.8168171166666,-10.4123898666667,129.00192885,-35.1899382666667
I'm proportionally calculating the pixels from the ratio of x/y, it does
the job =)
