-sample command create terrible quality pictures. Why u dont use -geometry command? first off all the quality with that command is exelent, and second, file size become smaller.

In "image_utils.php" file, edit the following line


".$quality." -antialias -sample $width"."x"."$height \"$src\"


Change the word '-sample' to '-geometry'

".$quality." -antialias -geometry $width"."x"."$height \"$src\"


You will get brilliant quality.

I was having trouble with image quality, so I searched around for the quality solution and found the answer.  Then I tried to share the answer with others to pass on the help.  Somehow, during the process, I found your posting.

I almost gave up on 4images.  I have been using Gallery 1.33 and it has been great, with only one exception that it does not have an attractive user interface.  I also like that you can click on the set size of the picture and get the original size so that the user can download the best quality picture.  If 4images can do this, it would definitly beat Gallery for my purpose.  So far, I am still using Gallery and watching 4Images.

BTW, another benefit of ImageMagick is the smaller files size, comparing to Netpbm and GD.  Yes, I am also wantering why, they chose '-sample' as the default setting.  That might have driven quite a lot of people from 4Images, like I almost did, because I use ImageMagick.

Hi Rocky,

I also tried Gallery before but later I changed to 4images.  It is because the performance of Gallery becomes very slow when you have lots of photos (I have over 30000).  Do you have the same problems or it is getting resolved?

Thanks!

Whee!
The increase in thumbnail-quality is huge!
Big thanx to Rocky :)

@Jan
Vorschlag: Mach' das zum Standard in den zukünftigen Versionen. Sieht einfach so aus, als könnte -sample kein Antialiasing, egal was dabeisteht.

Greetz,
