Version 1.0: first public release.
|
||
|
|
Version 1.1: fixed bug to set *error to FLI_OK when returning successfully from FLI_Open
|
||
|
|
added function FLI_Reset to reset the animation to the first frame
|
||
|
|
Version 1.2: added function FLI_Skip to skip the current frame without rendering
|
||
|
|
FLI_Animation->surface is now correctly locked and unlocked
|
||
|
|
the rwops stream is now part of the FLI_Animation structure and is closed inside FLI_Close
|
||
|
|
renamed FLI_Reset to FLI_Rewind
|
||
|
|
added function FLI_Version that returns the library version
