MLKStrokePoint
@interface MLKStrokePoint : NSObject
A single touch point from the user.
-
Horizontal coordinate. Increases to the right.
Declaration
Objective-C
@property (nonatomic, readonly) float x;
-
Vertical coordinate. Increases downward.
Declaration
Objective-C
@property (nonatomic, readonly) float y;
-
Time when the point was recorded, in milliseconds.
Declaration
Objective-C
@property (nonatomic, readonly, nullable) NSNumber *t;

Unavailable. Use
init(x:y:t:)
instead.Declaration
Objective-C
- (nonnull instancetype)init;
-
Creates a
StrokePoint
object using the coordinates provided as argument.Scales on both dimensions are arbitrary but be must be identical: a displacement of 1 horizontally or vertically must represent the same distance, as seen by the user.
Spatial and temporal origins can be arbitrary as long as they are consistent for a given ink.
Declaration
Objective-C
- (nonnull instancetype)initWithX:(float)x y:(float)y t:(long)t;
Parameters
x
Horizontal coordinate. Increases to the right.
y
Vertical coordinate. Increases going downward.
t
Time when the point was recorded, in milliseconds.
-
Creates a
StrokePoint
object using the coordinates provided as argument, without specifying a timestamp. This method should only be used when it is not feasible to include the timestamp information, as the recognition accuracy might degrade.Scales on both dimensions are arbitrary but be must be identical: a displacement of 1 horizontally or vertically must represent the same distance, as seen by the user.
Spatial origin can be arbitrary as long as it is consistent for a given ink.
Declaration
Objective-C
- (nonnull instancetype)initWithX:(float)x y:(float)y;
Parameters
x
horizontal coordinate. Increases to the right.
y
vertical coordinate. Increases going downward.
