XnView Software

Bicupic resize is the standard of all picture viewers. Why does XnView not support it? It just shows the raw image after resizing without applying any post-processing filters.

That's a misunderstanding. I don't mean converting. I'm thinking of post-processing when viewing a image and resizing it with "+" or "-", or when XnView automatically resizes it on view to fit the window.

Because of failing post-processing algorithms the quality is very poor in XnView.

Great, thanks.

With "Enlarge" enabled, it makes zooming is considerably slower. Esp. if you enable change zoom in fixed steps.

Would zooming only the viewable parts of the image increase speed?

Thought exactly the same. E.g. ACDSee calculates which part of the image is shown after the zoom and applies the filter just to this part. When the user moves the image it shows the unaltered image till the user let the mousebutton go (stops moving the picture) and applies the filter afterwards.

I would even go so far to call the current XnView behavior a bug because it will get exponentially slower the more is zoomed.

FYI: Yes it's a known problem

But the XnView MP version solves this issue !

Thanks, great to see this will be fixed. Minute hint: ACDSee's bicubic filter is still a little bit better (more agressive/"blurred") than XnViewMP's.
