Frame Object

Default values should be used when importing an OCA format if the data can’t be read or is not available.
If there is no default value, importing the OCA document should fail.

Name	Type	Default	Description
duration	int	1	The duration of the frame, in frames.
fileName	string	""	The path and name of the file of the frame. It is the relative path from the root of the OCA folder. It can be an empty string if and only if it’s a blank/empty frame (i.e. the name is "_blank" ).
frameNumber	int		The frame in the document at which the frames starts to be visible.
height	int	layer.height	The height, in pixels.
meta	object	{}	Any custom metadata associated to the frame. It must be an object, not a value or a list.
name	string	"_blank"	The name of the frame. It can be "_blank" for an empty frame.
opacity	int	1.0	The opacity of the frame in the range [0.0 - 1.0]. It must be multiplied by the containing layer opacity during the rendering process.
position	int[]	[layer.width / 2, layer.height/2]	The coordinates of the center of the frame, in pixels [X,Y] in the containing (Layer Object) coordinates; the origin [0,0] is the top left corner of the containing layer.
width	int	layer.width	The width, in pixels.
