QUEST Character Verification
STEP 5: Setting Number of Dilations
2-21-(11)
Even Extraction
The character string is divided into a specified number of characters and
extracted at even intervals.
3 characters
Forced Extraction
If the set number of characters cannot be extracted, select whether or not to
use forced extraction. The settings are OFF* or ON.
The forced extraction function extracts characters that are joined due to print-
ing errors or because they are inclined.
Forced extraction is enabled only when Gap search or Dilate extraction are
selected as the extract method.
Extract Direction
The direction setting is enabled only when Dilate extraction is selected as the
extract method. The direction choices are from left* or from right.
Character extraction is performed only until the set number of characters have
been extracted. If there are extra characters in the extracting region, these
characters can be ignored (excluded from the extracting process) by starting
extracting from the opposite direction.
Expiration date 01. 11. 07
Extraction is performed on 8 characters starting from the right, so final "e" in
"Expiration date" is ignored.
Set the number of dilations between 0 and 9 if dilate extraction has been cho-
sen as the extract method.
1. Select Dilate level.
