#parameter2: width and height of the new image

#This function only works with 24-bit or 32-bit surfaces. If the input surface bit depth is less than 24, an exception is thrown

img1 = pygame.transform.scale2x(img) # fast double size zoom

img = pygame.image.load('horse.jpg')
img1 = pygame.transform.rotate(img, 30) # rotate the image
#parameter 2: angle to rotate - positive number means counterclockwise - negative number means clockwise
# Unless rotated in 90 degree increments, the image will be padded to a larger size. If the image has pixel alpha, the filled area will be transparent
#rotation is around the center

img1 = pygame.transform.rotozoom(img, 30.0, 2.0) #scale+rotate
#The first parameter specifies the image to be processed, the second parameter specifies the number of angles to rotate, and the third parameter specifies the scale of the zoom
#This function will filter the image, the image will be better, but will be much slower

img1 = pygame.transform.chop(img, (0, 0, 100, 50)) #Crop the image
#The first parameter specifies the image to crop, and the second parameter specifies the area of the image to keep

img = pygame.image.load('horse.jpg')
img1 = pygame.transform.laplacian(img) # find the edge - outline
