Set Valid Characters (G Dataflow)

OCR session on which the node operates.

To create a session, use the Create OCR Session node.

Array of characters that are valid for a particular read character position.

The valid characters are stored at the array index that corresponds with the index of the read character that OCR is currently evaluating. For example, if OCR is evaluating the read character at index 0, it compares that read character to the valid characters that are stored at index 0 in the array of valid characters. The number of elements in the array is the number of characters that OCR reads. OCR ignores any array elements beyond this number.

pre-defined characters

Pre-defined valid character strings.

The following characters are the pre-defined characters for the corresponding position:

Name	Value	Description
any character	0	Any ASCII character
user-defined characters	1	Uses characters specified in the user-defined characters string.
alphabets	2	A-Z a-z
alphanumeric	3	A-Z a-z 0-9
uppercase letters	4	A-Z
lowercase letters	5	a-z
decimal digits	6	0-9
hexadecimal digits	7	0-9 A-F
pattern	8	Any Pattern
force space	9	Ignores the read character and forces a space at the corresponding position

user-defined characters

String of characters that is valid for the corresponding character position when pre-defined characters is set to user-defined characters.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error
