We then rotate the image using the rotate() function and inside of this function specify the degrees that you want to rotate the image. We specify 90 to rotate the image 90° counterclockwise. With the rotate() function, the value that you specify in the rotate() function is how much th...
In this OpenCV tutorial, we will learn how to rotate an image to 90, 180 and 270 degrees using OpenCV Python using cv2.getRotationMatrix2D() and cv2.warpAffine() functions, with an example. OpenCV Python – Rotate Image We can rotate an image using OpenCV to any degree. To rotate an i...
im.dtype, type(im)) # this image contains an α channel, hence num_channels= 4# (960, 1280, 4) float32 <class 'numpy.ndarray'>plt.figure(figsize=(10,10))plt.imshow(im) # display the imageplt.axis('off')plt.show()
cv2.imshow('Rotated Image', rotated_img) cv2.waitKey(0) 当rotateCode为cv2.ROTATE_90_CLOCKWISE时 当rotateCode为cv2.ROTATE_180时 当rotateCode为cv2.ROTATE_90_COUNTERCLOCKWISE时 文中,我们首先使用cv2.imread()函数加载了一个图像,然后使用cv2.rotate()函数将图像旋转,并将结果保存在一个新的变量rotated...
region = region.transpose(Image.ROTATE_180) pil_im.paste(region,box) Resize and Rotate To resize an image, call resize() with a tuple giving the new size: out = pil_im.resize((128,128)) To rotate an image, use counterclockwise angles and rotate() like this: out = pil_im.rotate(45...
旋转方法接受从image.load()函数加载的图像表面,并指定旋转的角度。通常,转换操作会调整像素的大小或移动部分像素,以使表面与显示屏兼容: pygame.transform.rotate(img, 270) #rotation of image by 270 degree 在我们开始开发自己的视觉吸引人的贪吃蛇游戏之前,您必须了解 Pygame time模块。点击此链接了解更多信息:...
