Hi i have some question about manipulation of images.

The situation is that we have a plain bitmap image (bmp). We want to

1.-convert it to black & white (monochrome)
2.-Get instead of the common black & white image, a ... hmmm how can i call it "binarized" image , you know having a bidimentional array of 0's and 1's , so we can apply some personalized algorithms.

I have accomplished the first step with imagemagick (mogrify -monochrome file) but i would like to know if there is a program or recommended approach to convert each one of those black/white pixes into 0's and 1's


Sorry about my english, not native.

Dood, bmp is pretty simple.

Thanks!! I'm checking it out. Im telling what happens next.

Ok, do tell.

Ok, basically i need to find a way to access this RGBQUAD array in a monochrome bitmap and check the lower and higher parts of all the bytes... with this info I could decide to turn each byte into a pair of 0 or 1 right?

Here's the php way to convert a picture to monochrome: http://www.captchakiller.com/php-convert-monochrome
