OpenCV-Python是旨在解决计算机视觉问题的Python绑定库。cv2.imwrite()
方法用于将图像保存到任何存储设备。这将根据指定的格式将图像保存在当前工作目录中。
用法: cv2.imwrite(filename, image)
参数:
filename:代表文件名的字符串。文件名必须包含图像格式,例如.jpg,.png等。
image:就是要保存的图像。
返回值:如果成功保存图像,则返回true。
示例1:
# Python program to explain cv2.imwrite() method
# importing cv2
import cv2
# importing os module
import os
# Image path
image_path = r'C:\Users\Rajnish\Desktop\GeeksforGeeks\geeks.png'
# Image directory
directory = r'C:\Users\Rajnish\Desktop\GeeksforGeeks'
# Using cv2.imread() method
# to read the image
img = cv2.imread(image_path)
# Change the current directory
# to specified directory
os.chdir(directory)
# List files and directories
# in 'C:/Users/Rajnish/Desktop/GeeksforGeeks'
print("Before saving image:")
print(os.listdir(directory))
# Filename
filename = 'savedImage.jpg'
# Using cv2.imwrite() method
# Saving the image
cv2.imwrite(filename, img)
# List files and directories
# in 'C:/Users / Rajnish / Desktop / GeeksforGeeks'
print("After saving image:")
print(os.listdir(directory))
print('Successfully saved')
输出:
Before saving image: ['geeks.png'] After saving image: ['geeks.png', 'savedImage.jpg'] Successfully saved
