Filter suggestion improvement

Open ProgramMax opened this issue 10 months ago • 1 comments

I met with @bitbank2 who mentioned this.

§ 12.7 Filter selection says "For images of color type 3 (indexed-color), filter type 0 (None) is usually the most effective." This isn't necessarily true. Filter selection is very situational.

The 'up' filter is quite effective on indexed images with large swaths of solid colors, such as logos.

We should improve our suggestions.
