摘要
通道是图形图像学上一个重要的概念,文章分析了各种通道的概念及形式,比较了三种不同形式的通道在图像处理中对选区的控制作用,揭示了通道转换成选区后是按照不透明度来填充整个图像区域的原理,但是要注意不透明度的计算方法在不同的情况下是不同的。
Channel is an important concept in graphics and images. This article analyzes the concepts of the various kinds of channel, compares three different kinds of channel that control the selection in image process, and shows the theory that full image region is filled according to opacity when channel is transferred to selection, but pay attention to computational method of opacity which is different in different conditions.
