List of used colors in drawing

[unitycoder]

one thing I'm trying to make the user get list of the colors he used to color his room walls i can just record the selected colors but if the user erased the color then it should not be in the list do u have i a way to do it without effect the performance and read the pixels colors again #7 (comment)

iterating through all the colors in pixels[] array should be ok (not too slow),
so could use that to collect which colors are used in drawing.. i can test it also.

i did a test but the results was too slow for the mobile

[unitycoder]

do you need to get the list only once at save? or more often? (could also skip every 2nd or 3rd pixel, probably not necessary to calculate small single pixels)

[fad12]

it could be more then one time

ok skipping some pixels was a good idea it worked well now thank u so much

[unitycoder]

closing this, probably could try doing the calculation in another thread also..but might get complicated.
