close

gif.close

Finalizes the animated GIF and completes file writing.

Overview

close finishes the GIF encoding process by writing the GIF trailer and closing the underlying file handle.

Calling this method ensures the animated GIF is valid and properly formatted.

Behavior

Writes the GIF trailer
Closes the output file handle
Resets internal encoder state
Prevents further frame additions

Safety

Calling close multiple times is safe
No exception is raised if the GIF is already closed
Safe to call even if no frames were added

Notes

Failing to call close may leave the GIF corrupted
Always call close after the last add_frame

Example

gif = GD::Gif.new("animation.gif")

img = GD::Image.new(200, 200)
img.filled_circle(100, 100, 50, GD::Color.rgb(0, 128, 255))

gif.add_frame(img)
gif.close

GD::Gif.new
