Public Constructors

public PAGLayer (long nativeContext)

Public Methods

public long currentTime ()

The current time of the layer in microseconds, the layer is invisible if currentTime is not in the visible range (startTime <= currentTime < startTime + duration).

public long duration ()

The duration of the layer in microseconds, indicates the length of the visible range.

public int editableIndex ()

Ranges from 0 to PAGFile.numTexts - 1 if the layer type is text, or from 0 to PAGFile.numImages -1 if the layer type is image, otherwise returns -1.

public boolean equals (Object obj)

public boolean excludedFromTimeline ()

Indicate whether this layer is excluded from parent's timeline. If set to true, this layer's current time will not change when parent's current time changes.

public float frameRate ()

Returns the frame rate of this layer.

public RectF getBounds ()

Returns a rectangle in pixels that defines the original area of the layer, which is not transformed by the matrix.

public double getProgress ()

Returns the current progress of play position, the value is from 0.0 to 1.0.

public Matrix getTotalMatrix ()

The final matrix for displaying, it is the combination of the matrix property and current matrix from animation.

public long globalToLocalTime (long globalTime)

Converts the time from the PAGSurface (global) to the PAGLayer's (local) timeline timeline. The time is in microseconds.

public int hashCode ()

public String layerName ()

Returns the name of the layer.

public int layerType ()

Returns the type of layer.

public long localTimeToGlobal (long localTime)

Converts the time from the PAGLayer's (local) timeline to the PAGSurface (global) timeline. The time is in microseconds.

public PAGMarker[] markers ()

Returns the markers of this layer.

public Matrix matrix ()

A matrix object containing values that alter the scaling, rotation, and translation of the layer. Altering it does not change the animation matrix, and it will be concatenated to current animation matrix for displaying.

public PAGComposition parent ()

Indicates the Container instance that contains this Node instance.

public void resetMatrix ()

Resets the matrix to its default value.

public void setCurrentTime (long time)

Set the current time of the layer in microseconds.

public void setExcludedFromTimeline (boolean value)

Set the excludedFromTimeline flag of this layer.

public void setMatrix (Matrix matrix)
