identify可以展示图像的详细信息，比如
图像格式(format)图像尺寸(geometry)颜色空间(colorspace)图像深度(depth)图像通道数(channel)通道统计数据(channel statistics)：包括ＲＧＢＡ各通道的统计数据（min,max,mean,std,skewness,entropy等)，总像素数量图像统计数据(image statistics)Ｇａｍｍａ值质量(quality)属性(properties)：创建时间，修改时间等图像文件大小(filesize)总像素数量(number pixels)查看详细输出需要添加输入参数 -verbose，例如：
identify -verbose sport.jpg输出结果为：
