How to change an image size in Pygame?

Question

There is the image I'm importing :

look_1 = pygame.image.load('data\png\look1.png').convert_alpha()

And what I tried to get its size reduce was this :

pygame.transform.scale()

But this seems not to be the right way to do it.

You can either use pygame.transform.scale or smoothscale and pass the new width and height of the surface or pygame.transform.rotozoom and pass a float that will be multiplied by the current resolution.

import sys
import pygame as pg

pg.init()
screen = pg.display.set_mode((640, 480))

IMAGE = pg.Surface((100, 60))
IMAGE.fill(pg.Color('sienna2'))
pg.draw.circle(IMAGE, pg.Color('royalblue2'), (50, 30), 20)
# New width and height will be (50, 30).
IMAGE_SMALL = pg.transform.scale(IMAGE, (50, 30))
# Rotate by 0 degrees, multiply size by 2.
IMAGE_BIG = pg.transform.rotozoom(IMAGE, 0, 2)


def main():
    clock = pg.time.Clock()
    done = False
    while not done:
        for event in pg.event.get():
            if event.type == pg.QUIT:
                done = True

        screen.fill(pg.Color('gray15'))
        screen.blit(IMAGE, (50, 50))
        screen.blit(IMAGE_SMALL, (50, 155))
        screen.blit(IMAGE_BIG, (50, 230))
        pg.display.flip()
        clock.tick(30)


if __name__ == '__main__':
    main()
    pg.quit()
    sys.exit()
