Module Video.CanvasSource

Videos with canvas images.

Sourcemodule Image : sig ... end
Sourcetype image = Image.t

An image.

Sourcetype t = image array

A video.

Sourceval make : int -> (int * int) -> t

Create a video with given length and dimensions.

Sourceval copy : t -> t

Make a copy of the video (images themselves are not copied since they are supposed to be immutable).

Sourceval single : Image.t -> t

Create a video with one canvas image.

Sourceval single_image : Mm_image.Image.YUV420.t -> t

Create a video with one image.

Sourceval length : t -> int

Length of the video (in images).

Sourceval size : t -> int

Estimated size of the video (in bytes).

Sourceval get : t -> int -> image

Get the nth image of the video.

Sourceval set : t -> int -> image -> unit

Set the nth image of the video.

Sourceval map_image : (image -> image) -> t -> int -> unit

Apply a function on the nth image of the video.

Sourceval render : t -> int -> Mm_image.Image.YUV420.t

Render the nth image of the video.

Sourceval put : t -> int -> Mm_image.Image.YUV420.t -> unit

Change the contents of the nth image of the video (like set but takes an image instead of a canvas as argument).

Sourceval blank : t -> int -> int -> unit

Blank the video starting at offset with given length.

Sourceval blit : t -> int -> t -> int -> int -> unit

Copy the images of one video to the other.

Sourceval map : (image -> image) -> t -> int -> int -> unit

Map a function to the images of a video (starting at given offset, for given length).

Sourceval iter : (Mm_image.Image.YUV420.t -> unit) -> t -> int -> int -> unit

Iterate a function on the rendering of the images of the video.
