转换tif到jpg

 2 import cv2
 3 import numpy as np

 8     img = io.imread(file_path_name)#读取文件名
 9     img = img / img.max()#使其所有值不大于一
10     img = img * 255 - 0.001  # 减去0.001防止变成负整型
11     img = img.astype(np.uint8)#强制转换成8位整型
12     # img = np.array([img,img,img])
13     # img = img.transpose(1,2,0)
14     # print(img.shape)  # 显示图片大小和深度
15     b = img[:, :, 0]  # 读取蓝通道
16     g = img[:, :, 1]  # 读取绿通道
17     r = img[:, :, 2]  # 读取红通道
18     bgr = cv2.merge([r, g, b])  # 通道拼接
19     cv2.imwrite(bgr_savepath_name, bgr)#图片存储
