这篇文章介绍一个Macro,可以做到对图像的框选部分进行像素展示(display pixel values),并且能判断图像的类型。对于RGB图像,可以分别展示3个通道的像素数值。 代码如下: 结果如下: 代码解析 代码可以分为三大部分: 一、获得图像参数(2-4行) getSelectionBounds(xbase, ybase, width, height);//Get selection inform...
ImageType[image] gives the underlying type of values used for each pixel element in the Image or Image3D object image.
