AnimationGlobalSize Property (original) (raw)
Summary
Gets or sets a value indicating the global size of the animation image.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public LeadSize AnimationGlobalSize { get; set; } @property (nonatomic, assign) LeadSize animationGlobalSize public [LeadSize](leadsize.html) getAnimationGlobalSize();
public void setAnimationGlobalSize(
[LeadSize](leadsize.html) leadSize
);
Property Value
A LeadSize structure that indicates the global size of the animation image. Default value is 0,0 meaning same size as the image
