图象的渐显/渐隐是十分重要的图象效果，广泛运用于图象处理和多媒提娱乐软件。渐显/渐隐算法设计的最大困难是速度控制，包括定时和快速改变图象中各象素的颜色。如采用普通的全图扫描算法，则速度较慢，很难真正体现渐显/渐隐效果-Image渐显/ fade effects are very important images, widely used in image processing and multi-media entertainment software mentioned.渐显/ fade algorithm design are the most difficult problems, speed control, including the timing and rapid changes in images of various pixel color. Such as the ordinary full-scan algorithm, while slow, it is difficult to truly embody渐显/ fade effects
