(c) Necessary Capacity of Data Matrix
The total remaining capacity of area1 to 4 shown in Table 6-11 is necessary for Data Matrix print.
For an example, when number of bar code data byte =20 and symbol size=22 (vertical)

22
(horizontal);
Area1 = 20 bytes
Area2 = 2230 bytes
Area3 = (30+20+1)

2 = 102 bytes
Area4-A = 1

(30+68)

Total = 2548 bytes (Area4 uses a value of Area4-A.)
(Assume that the remaining capacity is even number of bytes.)

*1: N: Number of bar code data
When remaining capacity of the RAM is an odd number, one more byte is necessary
When number of bar code data byte is an odd number, one more byte is necessary
*2: D: Number of data code word.
E: Number of error correction code word.
These values are decided from symbol sizes. See Table 6-12
*3: Area 4-A and area 4-B are used commonly. The larger number will be used
*4: The I will be calculated as follows:
・
When E is 68 or less, I=1
・
When E exceeds 68,
I=int
( )

When the above value is an odd number, plus 1 to the value.

*5: X: Horizontal size of the symbol
Y: Vertical size of the symbol
Xm: Horizontal size of the map matrix
Ym: Vertical size of the map matrix
See Table 6-12 for sizes of the map matrixes.
The int () means that less than a decimal point will be omitted.
