James Zern	4b9186b2eb	update issue tracker url ... code.google.com -> bugs.chromium.org Change-Id: I0dc99a85c29657415401160df3c7dd0423f96457	2015-10-19 20:06:50 -07:00
skal	bbe32df1e3	add alpha dithering for lossy ... new options: dwebp -alpha_dither vwebp -noalphadither When the source was marked as quantized, we use a threshold-averaging filter to smooth the decoded alpha plane. Note: this option forces the decoding of alpha data in one pass, and might slow the decoding a bit. The new field in WebPDecoderOptions struct is 'alpha_dithering_strength' (0 by default, means: off). Max strength value is '100'.
