Number.toString() is a little borked. Meister Skinner explains it here: http://www.gskinner.com/blog/archives/2005/12/source_code_tra.html Cheers, Claus. Jeroen Beckers wrote: var n:Number = -16777216 trace(n.toString(16)); Gives me: -100 ? Claus Wahlers wrote: pixel = -16777216

Re: [Flashcoders] BitmapData.getPixel() - negative value ?

Oooops, you are right, I meant 0x00 Nevertheless, you had said, 0xff00 (solid black) ?? It's because it has the alpha value on it (ARGB) with a opacity of 255 (100% opaque, or 0% transparent). 0x00 (or just 0) *IS* solid black, but if you're painting on a bitmap with an alpha

Re: [Flashcoders] BitmapData.getPixel() - negative value ?

Thank you for the link, I will surely read it! Since I don't need the alpha, I changed getPixel32 to getPixel (oh, sorry for wrong topic-title) and it works fine now. Thanks for all the input :-). (Oh, and I also noticed that I was dividing by 0x0, which is off course '0' and dividing

[Flashcoders] BitmapData.getPixel() - negative value ?

Hi list! I was trying to create a little class that generates a 2d grid from a perlinNoise-bitmap image. Now, when I perform the getPixel32(), it returns a negative value. I did some research and it appears you can get '-1' when the indexes are out of bounds, but that's as negative as it
