提供回呼 (Callback) 方法來判斷 GetThumbnailImage(Int32, Int32, Image+GetThumbnailImageAbort, IntPtr) 方法何時應該提前取消執行。

public: delegate bool Image::GetThumbnailImageAbort();

public delegate bool Image.GetThumbnailImageAbort();

type Image.GetThumbnailImageAbort = delegate of unit -> bool

Public Delegate Function Image.GetThumbnailImageAbort() As Boolean 

傳回值

Boolean

如果這個方法決定 GetThumbnailImage(Int32, Int32, Image+GetThumbnailImageAbort, IntPtr) 方法應該提前停止執行，則這個方法會傳回 true；否則會傳回 false。
