我正在PyGame上做一个简短的介绍,我需要模糊一些静态线条。经过两天的搜索,我找不到任何东西。
PyGame是否有内置方法来模糊形状或表面?我需要手动完成吗?什么是最好的方法来解决这个问题?
为了澄清,我不是在寻找运动模糊 - 我只需要一个简单的就地模糊,几乎就像一个发光的效果。
提前致谢!
答案 0 :(得分:3)
没有内置的模糊Surface
的方法。
解决方法是:
使用pygame.transform.smoothscale
缩放Surface
,然后恢复原始大小(丑陋)
迭代每个像素,获取相邻像素的颜色,计算红色,绿色和蓝色的平均值,并设置该像素的颜色(如果不使用像{{1 }})
我建议使用Python Imaging Library(PIL),因为它很好而且速度快。
这是一个简单且运行的例子:
numpy
提示:如果您在Windows上并希望安装PIL,请从here下载并通过
安装import pygame
from PIL import Image, ImageFilter
pygame.init()
screen = pygame.display.set_mode((512, 512))
