cv2.IMWRITE_PNG_COMPRESSION, 从0到9 压缩级别越高图像越小。 cv2.imwrite('1.png',img, [int( cv2.IMWRITE_JPEG_QUALITY), 95]) cv2.imwrite('1.png',img, [int(cv2.IMWRITE_PNG_COMPRESSION), 9]) 四、图片操作 1、使用函数cv2.flip(img,flipcode)翻转图像,flipcode控制翻转效果。
This tutorial will discuss compressing an image using the PIL library in Python. Before using the PIL library, install it using pip or python. pip install Pillow Python Image Compression Using PIL Library Image compression is used to reduce the size of an image. We know that images consist ...
