twisted.web: returning dynamically generated images as image/png
I have the following setup (see below), in which the render method of a RasterServer instance is responsible for generating a png file data in memory that then should be passed on to the client that made the request. However, I can't get my head around how to define the content-type for the render method result? Or whether that's possible at all? If not, how should I define my RasterServer so that it would return image/png content to the client? Cheers, Jussi ======================================== from twisted.web import resource, static, server from twisted.application import service, strports ... root = resource.Resource() ... raster = RasterServer() root.putChild('wms', raster) ... application = service.Application('test') mo_server = strports.service(where, server.Site(root)) mo_server.setServiceParent(application) ---------------- class RasterServer(resource.Resource): def render(self, request): ....

We actually just discussed something like this: http://twistedmatrix.com/pipermail/twisted-web/2009-August/004318.html You're looking for: request.setHeader('Content-Type', 'image/png') -phil
Right, figures. Thought it had to be something trivial, but failed to
see the obvious...
Thanks a million.

request.setHeader('Content-Type', 'image/png')
