The second stage performs run length encoding on the 32-bit pixel values.
In this case its pixel value) of the imaging device is seen.
And the criteria we make here is the same pixel value.
Each image can be represented as a vector of 1024 pixel values.
Each pixel value is a 2-bit index into a table of up to 4 colors.
Each pixel value is a 4-bit index into a table of up to 16 colors.
This works well when the distribution of pixel values is similar throughout the image.
This blend mode simply adds pixel values of one layer with the other.
The pixel values in these modes is only $0 and $1.
All nine color registers work on the display for pixel values 0 through 8.
