dither indicates if the image should be dithered - if it is true then dithering will be used which will result in a more speckled image but with better color approximation.
dither は、イメージにディザーをかけること を指定します。これが、 true の場合、ディザーが行われ、出力はぼやけ ますが、色の近似はより良くなります。

仮に 脳に電極を 差込んでも 彼が無事で うまく作動したとしても デジタル近似値の彼を 作ると言う事だ
