#249 unable to loop once when writing GIF

[Carnë Draug]

I am unable to create a GIF file that loops only once (plays the sequence twice). Using the animationIterations() method, setting to different values I get:

• animationIterations (0) - infinite loop
• animationIterations (1) - no loop (plays sequence 1 time)
• animationIterations (2) - loops twice (plays sequence 3 times)

I am checking this Gnome image viewer (gm display always exits after the last image).

I do not agree that a GIF animation should play a sequence three times given a Netscape extension loop count of 2. Testing with Firefox reveals that it shows the animation twice. Testing with 'gm animate' shows the sequence twice. The best reference I am able to find is

I looked at this some more. If I do what you ask, the Netscape loop extension will be added to GIFs which did not have it before.

Closing this bug too.
