change thumbnail quality

Hi, i tried to change the thumbnail compression quality.

After searching in config*.inc.php, the Web Gui and at the db i found nothing.
The single Google result what makes sense http://piwigo.org/dev/changeset/3271 seems to be outdated.

Where can i change it ?


best regards CvH

Piwigo 2.5.1

Re: change thumbnail quality

Doesn't this parameter only apply to ALL sizes ? not only thumbnails

Re: change thumbnail quality

Thumb and full size images have the same quality variable ?
Sound a little bit strange for me (because it make no sense).

I´ve tested with quality 98 and quality 50 (no lower value possible), cleared the cache (browser + piwigo) and
didn´t see any difference at the thumbs neither in quality or in size.
Maybe hardcoded value ?

the thumbnails are directly taken from piwigo cache
50.jpg -> 50%
98.jpg -> 98%

Re: change thumbnail quality

At piwigo 2.5.1 the jpeg quality setting does not work with the thumbnails.

I´ve tested with an Win and a Linux setting, same problems.

Could i manually change the value somewhere ?



For piwigo 2.6/7 ... it would be a nice addition (still wondering that there is no seperate setting).
