Question Avatar Resize Failure

Hello,

I'm using the Kunena latest module to show the latest posts, and I have it set to show Avatars with 100% quality with Bicubic resizing method from a gallery. All the gallery images are the same size, transparent PNGs. They display fine when full size and in the jComments latest comments module, but in the Kunena Latest Module, they either get a black background added to them, or they have 3/4 quadrants rendered and the last one transparent.

Example:

Resized


Original


Any idea what's causing this?

The black color is adopted from the alpha channel.
For such simple pictures you don't need Bicubic resizing method. Is more suitable for photos. Use Interpolation.

I switched the configuration back to Interpolation, cleared cache, and deleted the subfolder in /media/kunena/avatars/resized/size36/gallery that contained the avatars. A new folder was created and the avatars were resized again, however the issue still persists - there is a chunk missing from the top left corner.

Another example:

You have also uploaded the avatar again? The resize happens during the upload.

They are Gallery avatars, not user-uploaded avatars. I deleted the folder containing them in /media/kunena/avatars/gallery and re-uploaded. This reset all the avatars to default. I went to my profile and selected one from the newly uploaded gallery, and the same issue occurred again in the Kunena Latest Module.

Yes I have seen it now. Your image is corrupt. Use this image and it will work.

Do you know what part of it was corrupt? I have to fix 180 of those - hopefully I can just run them through Imagemagick to batch re-save and fix?

EDIT: Changing the max height/width from 36px by 36px to 90px by 90px and just resizing via CSS worked as a temporary fix. Would still be interested to know why 36px by 36px resizes break but the larger resizes do not?

If you use the avatar gallery then change the resized images in :
/media/kunena/avatars/resized/size42/gallery/
and
/media/kunena/avatars/resized/size36/gallery/
