Building a Mask File
The following mask uses all eight mask regions. The most difficult part of creating a mask
file is normalizing the X and Y values from the time and voltage values. This example
shows an easy way to convert voltage and time to normalized X and Y values in the mask
file.
The following mask file produced the mask shown above:
MASK_FILE_548XX
"All Regions"
/* Region Number */ 1
/* Number of vertices */ 4
-12.50, MAX
-10.00, 1.750
10.00, 1.750

/* Region Number */ 2
/* Number of vertices */ 5
