@gogs: Yes I know how to do that! My tutorial was written when we all used ActionScript 2.0 in Flash 8. I hope you got Flash 9 with ActionScript 3.0. I've seen an awesome tutorial about the BitmapData class in ActionScript 3.0; Re-Painting Pixels with Actionscript 3 It made me interested to see what's in the BitmapData class in ActionScript 3.0. There's a function that returns an ARGB color value that contains alpha channel data and RGB data. It was new for me I do not remember it being available in ActionScript 2.0 but I might be wrong. The tutorial is not yet using the alpha information but you can. See the BitmapData.getPixel32() function. Good Luck with it!

I wanna do the same thing but instead of getting average color of an image, i want the program to get me the average color of the whole movieclip with alpha information…

any clues??

Hi!
That error is caused because of the character “x” in the Hex numbers.
Just re-write that hex numbers by yourself and everything will work fine.

Yes it should work in Flash 8 (ActionScript 2) because that's the environment in which I made it. The errors are all related to syntax. So since the lines that are printed as errors are correct, I would make sure you have'nt missed an ')' or an ';' somewhere in the lines directly above sumColorG += (col & 0×00FF00) >>> 8; I hope that helps. I'm totally sure the code works, I have it running right now in a website of my own.

First of all THANK YOU for posting this code. It’s exactly what I am looking for. I am having trouble replicating it. I set up my flash document but I am getting the following error. Does it not work in Flash 8?
Any help would be a life saver… cheers

**Error** Scene=Scene 1, layer=Layer 3, frame=1:Line 26: ‘)’ expected
sumColorG += (col & 0×00FF00) >>> 8;

**Error** Scene=Scene 1, layer=Layer 3, frame=1:Line 27: ‘)’ expected
sumColorB += (col & 0×0000FF);

**Error** Scene=Scene 1, layer=Layer 3, frame=1:Line 30: Unexpected ‘}’ encountered
}

Total ActionScript Errors: 3 Reported Errors: 3

No problem. You’re welcome!

Theo, you’re a star … this is just what I was looking for and it works a treat! Dropping the sampling grid from every pixel to every 8th pixel speeds things up for larger images and is still accurate enough for what I want. Cheers.
