I need help with neopixel pixel set

Hello

Can any help me,

I have a 4 neopixel panel from 16x16 (256x4 1024)

Is there a shorter way to program an reset a pixel?
I will make some numbers or letters on the panel.
To set and reset,I made some new patch for this, than i made some segments (7 segments)pic 1
To make a number, I Set and reset this. pic 2
If i do it like this way my program is 575000 bytes and to big for a mega.
