Greyscaling a file?

[urger]

I've been working on this problem for a few days now and it still has me stumped. I need to take an image file (.bmp) and convert it to a greyscale image then output it. I've looked at several tutorials on graphics and so far haven't found an answer. :-?

- Open the BMP file
- Load all pixels in memory
(^^ tutorials explain a lot about how to do this)

- Convert the colors to greyscale using:

Code:

grey = red * 0.299 + green * 0.587 + blue * 0.114

with red, green, and blue the color components of each pixel, 0-255


Hope this helped a bit ^_^
