VC++为图片增加水波鼠标跟随效果的特效蒙版，动态的图片蒙版，鼠标在图片上晃动，会随机出现水波效果，晃动的越快，水波越多哦。用户还可以选择火焰和等离子效果，类似于给图片增加了一层蒙版的效果，很给力。

说明：  按照信息论基本原理的解释，信息是系统有序程度的一个度量，熵是系统无序程度的一个度量；如果指标的信息熵越大，该指标提供的信息量越大，在综合评价中所起作用理当越大，权重就应该越高。因此，可利用信息熵这个工具，计算出各个指标的权重，为多指标综合评价提供依据(According to the interpretation of the basic principles of information theory, information is a measure of the order degree of the system, and entropy is a measure of the disorder degree of the system. If the larger the information entropy of an index is, the greater the amount of information provided by the index is, and the greater the role it plays in the comprehensive evaluation, the higher the weight should be. Therefore, we can use the tool of information entropy to calculate the weight of each index and provide the basis for multi index comprehensive evaluation)
