L_BOOL LAnimationWindow::IsValidAnimation() const
Determines whether the LAnimationWindow object is valid.
Returns
TRUE |
The LAnimationWindow object is valid. |
FALSE |
The LAnimationWindow object is not valid. |
Comments
Before you can use any of the animation playback functions, a valid LBitmapList object must be associated with the class object. Until you have associated a bitmap list with the LAnimationWindow object, the object is considered invalid.
You can associate a bitmap list with the LAnimationWindow object using the constructor(LAnimationWindow::LAnimationWindow), LAnimationWindow::SetBitmapList, or LAnimationWindow::Load.
Note: This function also determines whether the current file is an animated GIF file. If the file contains more than one page, the function will return TRUE.
