Title: FloydSteinbergDithering bug
Post by: dilshod on February 13, 2017, 07:49:14 am

Hi,
In the FloydSteinbergDithering script, i found lines:

Code: [Select]

case TextureFormat.RGB565:
quantShiftR = 5;
quantShiftB = 6;
quantShiftG = 5;
quantShiftA = 0;
break;

imho, it should be:

Code: [Select]

case TextureFormat.RGB565:
quantShiftR = 3;
quantShiftB = 3;
quantShiftG = 2;
quantShiftA = 0;
break;

Hi,

Yes you're right, that was left behind from when it multiplied up and scaled back down as opposed to what its doing now. I will fix that, thanks for the bug report.

ps. Also the RBG order, ugh. How on earth did you find this?

I was trying different dithering algorithms. I found Sierra Lite gives better dithering compared to others. And making small manipulations on input and output color gives better result.
