javascript - Photo filter - pixelate (mozaik), rotate 45deg and take color of these squares? -


need algorithm :

original: enter image description here

after effect: enter image description here

and after effect want take color of every square ( save x,y,rgb);

first idea resize image. if need 32x32 image resize normal image 64x64 , take every second pixel. , every second row move x+1.

any better ideas? me important colors info. dont' need image, colors.

edit:

i found code : http://www.exorithm.com/algorithm/view/pixelate .

so think. first rotate image 45deg, procces code, save color of each square, procces data colors matrix transform. possible rotate pixels data 45 deg?

p.s. i'm doing in javascript, jq etc.
