I am trying to make a program to change certain pixels of a bitmap, specifically to hide information. Anyway, my problem would be the fact that I don't know how to read a bitmap's bits one at a time. Then I don't know how to change those bits and save them back to the file. pls hlp, thx :-)
That's probably the first time I say something against Megatrons answer, but this doesn't allow to get all bits of the pixels at one time. Go to http://www.ur.co.nz
There are several tutorials in which is explained, how to get a bitmap into an array. so you got the array with all bits in it.
