Logging recognition events

Aspose.OCR for C++ can show recognition progress in the console or log it to a file. The logging is activated with asposeocr_set_log_settings() function. You can specify the following logging parameters:

Property	Description
console_output_enabled	Set to true to enable the display of recognition progress in the console.
logging_level	Specify the log severity. See Log severity levels for details.
output_path	Specify an absolute or relative path to the log file.

Log severity levels

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

Severity	Description
ASPOSE_OCR_LOG_ERROR	Error events of considerable importance that will affect normal program execution.
ASPOSE_OCR_LOG_WARNING	Potentially harmful situations that might still allow the application to continue running. The log will also include errors (as if ASPOSE_OCR_LOG_ERROR is specified).
ASPOSE_OCR_LOG_TRACE	Detailed trace messages useful for application developers. The log will also include errors and warnings (as if ASPOSE_OCR_LOG_ERROR and ASPOSE_OCR_LOG_WARNING are specified).

Example

AsposeOCRLogSettings log_settings;
log_settings.console_output_enabled = false;
log_settings.logging_level = ASPOSE_OCR_LOG_ERROR;
log_settings.output_path = "errors.log";
asposeocr_set_log_settings(log_settings);
