[xwiki-users] blurry images
Hello everyone, my xwiki seems to do strange things to embedded pictures. No matter how big the resolution is they all are displayed blurry (as if they were scaled down and then up again). Can anyone explain that behavior? Does anyone know what to do against it? Thank you for your help, Stephanie
Stéphanie, my XWiki never did image refactoring. However, my UMTS stick internet provider (1&1, through vodafone, could be the same with SFR) does it always by default: it applies fairly strong jpeg compression to any image request. That gives a pretty dusty web effect which is pretty horrible and can only gotten rid of by actually emptying cache. hope it helps. paul Le 6 juin 2011 à 21:50, [email protected] a écrit :

Does this happen only with attached images or even with external images? If you have this problem only with attached images, then how do you embed them? If you're using wiki syntax and you specify the size like this: [[image:[email protected]||width="300"]] then the image is resized on the server side to optimize the amount of data transferred to the client. You can disable this from the xwiki.properties file (rendering.imageDimensionsIncludedInImageURL) or increase the level of quality from xwiki.cfg file (xwiki.plugin.image.defaultQuality, 0.5 by default, 1 meaning best quality). Hope this helps, Marius
