1.2.1 Instance variables

animation <- file: source_sink*

Where the frames were loaded from, or @nil if the animation was made by appending frames.

animation <- frames: vector

The frames, as images. All frames have the same animation<-size: the file describes the complete picture for each frame, also if it only stores what changed.

animation <- delays: vector

For each frame, the number of milliseconds it is shown. Animations often use 0 (GIF) for "as fast as possible"; bitmap->play shows frames of 10 milliseconds or less for 100 milliseconds, as web browsers do.

animation <-> loop_count: int

How many times the animation is played. 0 means forever. animation->save writes it.

animation <-> title: char_array*

animation <-> author: char_array*

animation <-> description: char_array*

animation <-> copyright: char_array*

Text stored in the file, or @nil. animation->save writes them. PNG and WebP files hold all of them; GIF files only the description.

animation <- size: size

The size of the frames.

animation <- recording: frame|window*

The frame or window animation->record is recording, or @nil.
