Question

我有长方形：

rect = pygame.Rect(10, 20, 100, 200)

和图像：

img = pygame.image.load('ace_of_hearts.jpg')

如何更改较大(或较小)的图像以适应矩形(与图像的初始比率)？

Answer 1

def resizeInto(surface, rect):
    surSize = list(surface.get_size())
    rectSize = rect.size
    for i in (0, 1):
        if surSize[i] > rectSize[i]:
            surSize[1 - i] = 1. * surSize[1 - i] / surSize[i] * rectSize[i]
            surSize[i] = rectSize[i]

    if surSize != surface.get_size():
        rounded = [int(round(s)) for s in surSize]
        surface = pygame.transform.smoothscale(surface, rounded)
    return surface

Answer 2

你可以这样做：

rect = pygame.Rect(10, 20, 100, 200)
img = pygame.image.load('ace_of_hearts.jpg')
img = pygame.transform.scale(img, rect.size)
# rect.size returns (100, 200)

希望这能有所帮助！
