Class PAGLayer

Returns a globally unique id for this object.

Returns the type of layer.

Returns the name of the layer.

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.

Resets the matrix to its default value.

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

Returns the current alpha of the layer if previously set.

Set the alpha of the layer, which will be concatenated to the current animation opacity for displaying.

Whether or not the layer is visible.

Set the visible of the layer.

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.

Returns the parent PAGComposition of current PAGLayer.

Returns the markers of this layer.

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

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

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

Returns the frame rate of this layer.

The start time of the layer in microseconds, indicates the start position of the visible range in parent composition. It could be negative value.

Set the start time of the layer, in microseconds.

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

Set the current time of the layer, in microseconds.

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

Set the progress of play position, the value ranges from 0.0 to 1.0. A value of 0.0 represents the frame at startTime. A value of 1.0 represents the frame at the end of duration.

Set the progress of play position to the previous frame.

Set the progress of play position to the next frame.

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

Returns trackMatte layer of this layer.

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.

Set the excludedFromTimeline flag of this layer.

Returns true if this layer is a PAGFile.

Returns this layer as a type layer.
