## Discussion

Value must be a <doc://com.apple.documentation/documentation/CoreFoundation/CFBoolean> object. Default is <doc://com.apple.documentation/documentation/CoreFoundation/kCFBooleanFalse>. A value of <doc://com.apple.documentation/documentation/CoreFoundation/kCFBooleanFalse> indicates that horizontal glyph forms are to be used; <doc://com.apple.documentation/documentation/CoreFoundation/kCFBooleanTrue> indicates that vertical glyph forms are to be used.
