You use these constants to specify the degree of line justification for a single line or an entire text layout object. You can set the line justification text layout attribute for a line or an entire text layout object by passing the kATSULineJustificationFactorTag tag the functions ATSUSetLineControls and ATSUSetLayoutControls, respectively.
enum {
kATSUNoJustification = 0x00000000L,
kATSUFullJustification = 0x40000000L
};
Constant descriptions
kATSUNoJustification
