Hi,

Could it be possible to have some more informations about the resize algorithm ? I can see many filters about resizing images (lanczos, triangle, mitchell, etc. but which one should I use ?
which one is better, which one is faster ? I heard about BiCubic, is Cubic the same ? It's good to have many filters but I think the non-specialist end-user just cares for quality (speed no longer really matters whith current processor)

With next digiKam 8.4.0, a new G'MIC processor tool for the Batch Queue Manager
will be available. The G'MIC scaling filters has the desired options :

Plenty of other G'MIc tools are also available for your workflow, and
more (in fact over 600 filters to process photo). The settings from an Image
Editor G'MIC-Qt filter can be backported to the BQM using the 'copy' button on
the top of the dialog.
