GIF (or rather Netscape's Application Block) does not allow you to start looping a subset of all frames. Impose a slowness fine for values of 0 and 1. However this frame takes up less space in the GIF.įrames are also much slower when StringCanvas is used.Ī duration of 2/100-ths of a second is the minimum, since browsers But in some cases it cannot be used, and compression is done in PHP, which is much slower.įrames are fast when GdCanvas or FileImageCanvas is used in combination with a local color table (the default).įrames are much slower when the global color table is used. The library uses GD's imagegif function to generate frames quickly.
