Using the Most Restrictive Mask
l
Target: Form designer.

What: In the Capture Options tab of a Capture object, the mask type indicates the type of
character to be recognized. There are 3 possible selections: numeric, alphabet and
alphanumeric. The alphabetic mask type allows you to select the letter case.
The following guidelines are applicable when configuring a PlanetPress Capture object
that utilizes ICR:
l The collected data is expected to be a number, therefore the numeric mask type must be
selected, or
l The collected data is expected to be a letter, therefore the alphabet mask type must be
selected,
l
If upper case letters are expected, select Upper case in the Case option menu. The
captured characters would be immediately converted to capital letter i.e. the ICR engine
will recognize a lower case a but will display it in upper case.
l
If lower case letters are expected, select Lower case in the Case option menu. Same as
for upper case letters, the captured characters would be converted to lower case and
displayed as such.
l If proper names or nouns are expected (i.e. only the first letter must be a capital letter),
select Capitalization in the Case option menu. Only the first letter would be converted to
a capital letter.
l
If no specific format is expected, select None in the Case option menu. The letters will be
interpreted as written, no conversion will be done i.e. characters in lower case will be
displayed as such.
l The collected data is expected to be a combination of numbers and letters, therefore the
alphanumeric mask type must be selected.
Why: Reducing the number of expected characters increases the probability that the correct
one is matched. This allows us to avoid that the letter l (a lowercase L) is not recognized as the
numeric value 1 (one) and vice versa. Or, if the mask type is identified as alphanumeric, there’s
a possibility that the letter a is recognized as 2; since Capture will also interpret how the
movement was traced.
