[Geoserver-users] jpeg quality in WMS output

GeoServer GeoServer User
1

Hello,

I need to raise the jpeg quality when using it as output format for WMS. I’m using geoserver 1.6.5 and, to my surprise, when looking around I couldn’t find any way to do this.

Is there a setting for this that I’m not seeing, or is it indeed a missing feature?

Ciao Bjorn,
actually, you are right, there is no way to configure this. Default
quality is 75% (visually lossless).
It could be implemented quite easily though, but I guess it is the
kind of the thing that gets procrastined indefinitely unitl someone
really needs it :-).

Hehe, well I really need it :wink:

Seriously though, if this is a very low priority thing, we would like to patch it ourselves. If you could point out the class that we need to tinker with it would be much appriciated.

Well,
actually, quite a few things would be involved at both the geotools
and geoserver level. It takes more time to explain it than to do it
:-).
Thinking...., you might want to track down how the hint to use non
native jpeg writer is implemented through the various layers. When you
get to the ImageWorker class in geotools, I'll tell you how to change
writer settings.

Hmm first time looking at the gigantic source that makes up geotools and geoserver I don’t understand much of “the hint to use non native jpeg writer is implemented through the various layers.” :slight_smile:

But looking at JPEGMapProducer.java line 47:

new ImageWorker(image).writeJPEG(outStream, “JPEG”, 0.75f, JPEGNativeAcc.booleanValue());

Wouldn’t a quick and dirty fix be to adjust the value, recompile and replace?

Ciao Bjorn,
if what you are looking for is a quick & dirty fix, what you describe
above would do what you need?
I thought you wanted the capability to this kind of stuff from the UI...

Doing this the proper way and including in GUI would be nice, but wanted to raise the jpeg quality quickly in a production enviroment.

Perhaps later I’ll be confident enough with the code base to contribute this but for now thanks for confiming the quick fix.
