v1.63: WebP unable to set 100% quality

Post by o-l-a-v » Thu May 01, 2014 1:52 pm

Hi!

WebP is supposed to work as both a lossy and lossless codec. But when you can't set the output quality to be 100% in XnConvert, it's not possible to create lossless images with WebP.
WebP does also have a bunch of usefull switches that i'd really like to adjust in order to get the output I want.
Could you please add these things for future releases?

Thanks

Well, the paint.NET plugin has several.

It has "quality", "Encoding speed/ quality", "Spatial Noise Shaping", "Filter strength", "Sharpness". Don't know if all of them is in the webp codec itself. But encoding speed/ quality would be nice :)

Version 1.63 - windows x64 (Feb 10 2014) - Libformat version 6.55


I explicitly downloaded Xnconvert to convert a large collection of screenshots into webp lossless. Also note 100% is still lossy and I would like to request a lossless checkmark. Lossy webp even at 100% changes color through entire images and to me its glaring. Thanks for your time in this, its a great product
