I don't have access to the system right now, but I can try and report back.

However, if the remote display is configured to have a maximum size of 640 x 480, then I do not believe there is any way to request a larger image from the client side. Perhaps someone else knows otherwise though.

However, I have found that the remote X display I'm using is set to a resolution of 640x480. Given that info, it might make sense that ParaView is not rendering anything bigger than 636x420 if it's restricted to the X display's size. Is it possible to get around the size of the remote X display when rendering something offscreen with ParaView?

If you built the ParaView release you're running yourself, you could always try to check out the topic and see if it fixes the issue you're seeing.

I've noticed that the image quality for ViewPorts seems bad regardless of what is specified in the call to viewport.image.render (docs here: http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/api/protocols.ParaViewWebViewPortImageDelivery<http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#%21/api/protocols.ParaViewWebViewPortImageDelivery> ). After decoding the returned image from the Base64 encoding, the JPEG image comes out as 636x420, while the quality is listed as 100 and the original size is 1440x850. The JSON object passed to viewport.image.render looks like {"args":[{ "localtime":1425413914878, "view":-1, "size":[1440,850], "quality":100}] } While the returned object from that RPC call looks like { "image": "very long encoded image text here", "localTime": 0, "stale": false, "size": [1440,850], "format": "jpeg;base64", "global_id": "315", "mtime": 3068929, "workTime": 1 } I've used two separate Base64 decoders, and both result in a JPEG image that is 636x420, not the reported 1440x850. Any idea what could be the problem here? Is this a bug in ParaViewWeb? I'm running the latest stable ParaView release (4.3.1) on RHEL.
