Now, I'm having a very difficult problem
I convert a font to hex code, and can resize it
as follows :  

1. I use lcd font maker software to create char A font Arial size 18  

2. Then I convert to hex code  

(see picture to understand)

How do I resize the image when data input is hex code or binary, and result is hex code or binary?
Please suggest me, or document related to this issue.
