resize

Please correct me if I'm wrong but i'm under the impression that resizing of the thumbnails and display images is done with ordinairy resize functions of e.g GD. The display images and thumbnails could be greatly improved in quality if they weren't resized but resampled (e.g. with the bicubic algorithm), these functions should probably also be available in GD or imagemagick. This would prevent aliasing artifacts in the images.

BTW thanx for the 1.11.9 release, keep up the good work Wink

greetings,
Tom

Re: resize

I am sorry to disappoint you but the resampling functions from GD2 are used.
The only thing I am thinking of implementing in the thumbnail creation is a sharpening function.
I never noticed any aliasing artifacts though.

My personal experience is that quality is worse with relatively small thumbs (< 80 pixels). I have good results with 100px.

Re: resize

You didn't disapoint me (actually I'm pleased to hear it), I wasn't even sure but I just thought the quality of the thumbs was not as high as I thought it could be. Then I figured this could have been the problem but apparently it wasn't. I'll just have to adjust my expectations Tongue

I will just make the thumbs a bit larger.

Thanx
