摘要
Alpha通道本质上是采用8位二进制数存储于图象文件中代表各像素点透明度的附加信息,Alpha通道技术因而成为图象合成最基本技术,利用它能够创作出十分丰富的图象效果,并在Photoshop、3dmax、Flash、Premiere等多媒体素材软件以及Authorware多媒体集成工具中得到广泛应用。
Alpha Channel is essentially used to store graphics files in the form of 8-digit binary digit, representing additional information of the transparence of each PIX. It has become the most fundamental skill in graphic combination, and can create a big variety of graphic effects. It is now being widely applied in many multi-media software such as Photoshop, 3Dmax, Flash, Premiere and Authorware.
