reading image pixel
Posted on 1999-11-03
i do not know whether this is the right topic or not.
the problem is, i have 2 image files. it is the same image, but slightly different of their position. the background of this image is white, and the image colour is black. my task is to calculate the difference of that 2 images(in pixels). can i do this with c? can c language differentiate the colour difference? some people told me to use cortex, but i do not know where to get it. can this be done by using only c without other libraries?
