Images distorted using pygame

问题:

Trying to build my first pygame project and wanted to import the following map. Used image:

My code is:

import pygame
pygame.init()
size = (1300, 700)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("My Game")
done = False
clock = pygame.time.Clock()
map = pygame.image.load('map.jpg')
map = map.convert()
map = pygame.transform.scale(map, (466,700))
while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
    screen.fill((255,255,255))
    screen.blit(map, (430, 0))
    pygame.display.flip()
    clock.tick(60)
pygame.quit()

and the output looks like:

I have also tried converting the jpg to a bmp but still the same results. I cannot figure out what is distorting the image, trying with other images it appears that the outputted images is slightly wider than the original. I suspect that pygame is just reading the width wrong and then putting the pixels into an array with that width.

Any advice on fixing this would be much appreciated.

There is a bug in SDL_image (which Pygame is based on) that corrupts images in OS X 10.11.

Currently, the only known workaround is to downgrade to SDL_image 1.2.10, but I have not been able to confirm.
