如何在pygame中绘制透明图像?

问题描述：

考虑一个国际象棋棋盘，我有一张女王/王后(queen.png)的透明图像，尺寸为70x70，我想在黑色矩形上显示它. 代码:

Consider a chess board, i have a transparent image of queen(queen.png) of size 70x70 and i want to display it over a black rectangle. Code:

BLACK=(0,0,0)
queen = pygame.image.load('queen.png')

pygame.draw.rect(DISPLAYSURF, BLACK, (10, 10, 70, 70))
DISPLAYSURF.blit(queen, (10, 10))

错误:我没有得到透明图像，即黑色矩形根本不可见，只有女王带有白色背景. 请建议

Error: i am not getting transparent image ie black rectangle is not visible at all, only queen with white background. Please suggest

答

尝试将皇后加载的行更改为:

Try changing the line where you load in the queen to:

queen = pygame.image.load('queen.png').convert_alpha()
