)

Overloads Sub SetEnumValue( _ 
   ByVal settingName As String, _ 
   ByVal value As String _ 
)

void SetEnumValue(  
   string settingName, 
   string value 
)

- (void)setEnumStringValue:(NSString *)value  
                forSetting:(NSString *)settingName

public void setEnumValue(String settingName, 
                         String value)

function Leadtools.Forms.Ocr.IOcrSettingManager.SetEnumValue(String,String)(  
   settingName , 
   value  
)

void SetEnumValue(  
   String^ settingName, 
   String^ value 
)

Parameters

settingName
Unique setting name. If the IOcrEngine does not support the setting with the unique name settingName, an exception will be thrown. You can check which settings the engine supports by using GetSettingNames or IsSettingNameSupported

value
The new setting value as a string

Remarks

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

If the enum is not a flag enum type (the value of IOcrSettingDescriptor.EnumIsFlags of the IOcrSettingDescriptor for this setting is false, then the string value of the setting is the friendly name value of the enum member (The enum member values and their friendly names can be obtained with IOcrSettingDescriptor.GetEnumMemberValues and IOcrSettingDescriptor.GetEnumMemberFriendlyNames)

If the enum is a flag enum type (the value of IOcrSettingDescriptor.EnumIsFlags of the IOcrSettingDescriptor for this setting is true, then the string value of the setting is the friendly names of the flagged set separated by a comma.

The string enum values are case-sensitive.

To set the enum value as a string value, use SetEnumValue.

To get or set the value of an enum setting as integer, use GetEnumValue and SetEnumValue.

You can also set the value of any setting from a string (where the string will be converted to a compatible type) using SetValue. To get the value of any setting as a string, use GetValue Note that settings of type OcrSettingValueType.BeginCategory and OcrSettingValueType.EndCategory have no values and will throw an exception if you try to get or set their values.

IOcrEngine is a wrapper for different OCR engines. These engines contain specific additional features and functionalities that can be queried and updated using the IOcrSettingManager interface.

You can use the different methods of the IOcrSettingManager interface 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 GetSettingNames method. The GetSettingDescriptor method 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 OcrSettingValueType.Integer, you can use the GetIntegerValue to get the current value of the setting and the SetIntegerValue to change its value. Refer to IOcrSettingManager for a complete example.

For a list of supported engine-specific settings and their meanings, refer to OCR engine-specific Settings.
