I am trying to understand how text is stored in images in LSB.
If we consider a 24 bit image, we have 3 values per pixel (RGB). So we can store 3 bits in a pixel. So how do we store 'A' or any other character in this situation? Do we store 6 bits in 2 consecutive pixels and then last 2 bits in RG of next pixel and then start storing the first bit of next character from B of the same pixel?
Also, is there a standard for this? E.g. should we start from the first pixel always? If not, is there a way to guess by looking at the pixel values from where the data is stored?
