Get Character Information (G Dataflow)

Last Modified: October 25, 2017

Retrieves information about the trained character at the specified index.

connector_pane_image
datatype_icon

internal image in

Internal representation that OCR stores for the character.

internal image in is an 8-bit image.

datatype_icon

OCR session in

OCR session on which the node operates.

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

datatype_icon

character image in

Image used to train the character.

character image in can be of type 8 bit, RGB, or HSL.

datatype_icon

error in

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

datatype_icon

character index

Index of a character in the character set.

datatype_icon

internal image out

Internal representation that OCR stores for the character.

internal image out is valid only if you specified internal image in.

datatype_icon

OCR session out

OCR session on which this node operates.

datatype_icon

character image out

Image that OCR used to train the character.

character image out is valid only if you specified character image in.

datatype_icon

character value

Value of the corresponding character.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

datatype_icon

reference character?

Boolean that specifies if the character is the reference character for the character class.

TRUE Character is the reference character for the character class.
FALSE Character is not the reference character for the character class.
