Returns

Comments

Sets the current value of a double setting.

The settingName setting must be a "double" type setting, otherwise; this method will return an error. To get the type of a setting along with other information such as its friendly name and range use the L_OcrSettingManager_GetSettingDescriptor method.

To get the value of a double setting, use L_OcrSettingManager_GetDoubleValue.

You can also set the value of any setting from a string (where the string will be converted to a compatible type) using L_OcrSettingManager_SetValue. To get the value of any setting as a string, use L_OcrSettingManager_GetValue. Note that settings of type L_OcrSettingValueType_BeginCategory and L_OcrSettingValueType_EndCategory have no values and will return an error if you try to get or set their values.

LEADTOOLS OCR Module - LEAD Engine contain specific additional features and functionality that can be queried and updated using different L_OcrSettingManager handle functions.

You can use the different methods of the L_OcrSettingManager handle to get and set the engine-specific settings. Each setting has a unique name (a string value). You can get all the settings available to the current OCR engine through the L_OcrSettingManager_GetSettingName method. The L_OcrSettingManager_GetSettingDescriptor and L_OcrSettingManager_GetSettingDescriptors methods returns a description of the setting (its type, friendly name and value range), you can then use the various setting get and set methods to query and change the value of a certain setting. For example, if the setting type is L_OcrSettingValueType_Double, you can use the L_OcrSettingManager_GetDoubleValue to get the current value of the setting and the L_OcrSettingManager_SetDoubleValue to change its value. Refer to L_OcrEngine_GetSettingManager for a complete example.
