今天在简书，上看到了一个 bmp转jpg的代码，便记录一下。
# coding:utf-8
import os
from PIL import Image# bmp 转换为jpg，灰度图转RGB
def bmpToJpg_grayToRGB(file_path):
for fileName in os.listdir(file_path):
print(fileName)
newFileName = fileName[0:fileName.find(".bmp")]+".jpg"
print(newFileName)
im = Image.open(file_path+"\\"+fileName)
rgb = im.convert('RGB') #灰度转RGB
rgb.save(file_path+"\\"+newFileName)# 删除原来的位图
def deleteImages(file_path, imageFormat):
command = "del "+file_path+"\\*."+imageFormat
os.system(command)def main():
file_path = "D:\\models-master\\research\\object_detection\\images"
bmpToJpg_grayToRGB(file_path)
deleteImages(file_path, "bmp")if __name__ == '__main__':
main()
