When m=0, 1, 2, 3, 4 or 6 

・

n1 and n2 indicate the number of dot positions. 

n1: The remainder from dividing the number of dot positions by 256 

n2: The quotient from dividing the number of dot positions by 256 

・

First, the data is lined up in one row as shown below. 

・

One dot of the image data is enlarged according to the value of m, as shown below. 

・

As a result, the image is sized depending on the value of m, as shown below. 

            m=0 

48 dots vertically × (n1 + n2 * 256) * 6 dots horizontally 

            m=1 

48 dots vertically × (n1 + n2 * 256) * 3 dots horizontally 

            m=2 

48 dots vertically × (n1 + n2 * 256) * 3 dots horizontally 

            m=3 

48 dots vertically × (n1 + n2 * 256) * 2 dots horizontally 

            m=4 

48 dots vertically × (n1 + n2 * 256) * 4 dots horizontally 

            m=6 

48 dots vertically × (n1 + n2 * 256) * 4 dots horizontally
