Logging recognition events

Aspose.OCR for Python via .NET can show recognition progress in the console or log it to a file. The logging is activated with a static Logging class. You can use the following properties to activate logging and specify its parameters:

Property	Description
console	Set to true to enable the display of recognition progress in the console.
file_system	Set to true to write recognition progress to a file specified in log_file_path property.
log_file_path	Specify an absolute or relative path to the log file. Applicable only when the file_system property is set to true.
logging_level	Specify the log severity. See Log severity levels for details.

Enable logging

Logging.console = true;
Logging.file_system = true;
Logging.log_file_path = "recognition.log";
Logging.logging_level = LoggingLevel.DEBUG;

Log severity levels

You can configure the log severity by specifying one of the following values in logging_level property:

Severity	Value	Description
LoggingLevel.ERROR	2	Error events of considerable importance that will affect normal program execution.
LoggingLevel.WARNING	1	Potentially harmful situations that might still allow the application to continue running.
LoggingLevel.DEBUG	0	Detailed trace messages useful for application developers.
LoggingLevel.NONE	3	No logging. Works the same as turning off logging with console and file_system parameters.
