hi,

thanks for your reply, the thing u have suggested will solve my problem upto
40% again the prob araises when we want to count the pixels for irrugular
shapes.. let us say curvy line.. i want only to calculate that line portion of
the image.. we should not consider other than the line area... is it possible..

thanks in advance...

bye

You can try in this way , when image is loaded launch this script :

x = yourclip._x;
y = yourclip._y;
h = yourclip._height;
l = yourclip._width;
area = 0;
for (pixel_y=y; pixel_y<(y+h); pixel_y++) {
for (pixel_x=x; pixel_x<(x+l); pixel_x++) {
//trace(this.hitTest(pixel_y, pixel_x, true));
if (this.hitTest(pixel_y, pixel_x, true)) {
area = area+1;
}
}
}
trace("AREA="+area);

area is the total number of pixel.

I think it is not pertinent, as even in an irregular image (bitmap mode) the
total pixels will be that of the rectangle encompassing the image. In other
word the transparent part is considered as a color. If you are talking about
a vector drwawing, the amountof pixels is less relevant as the image is
created on display only. Inside the memory the vector image is stored as a
range of ... vectors and x,y points.
