pygame.transform.flip
pygame.transform.flip() is a method in the Pygame library that is used to flip an image along its axis. This method can be used to create mirror images or to change the orientation of an image. The method takes three arguments: the image to be flipped, a boolean value indicating whether to flip the image horizontally, and a boolean value indicating whether to flip the image vertically.
Syntax:
```
pygame.transform.flip(surface, xbool, ybool)
```
- surface: The image to be flipped.
- xbool: A boolean value indicating whether to flip the image horizontally (True or False).
- ybool: A boolean value indicating whether to flip the image vertically (True or False).
Example:
```
import pygame
pygame.init()
# Set up the display
display_width = 640
display_height = 480
game_display = pygame.display.set_mode((display_width, display_height))
# Load the image
my_image = pygame.image.load("image.png")
# Flip the image horizontally
flipped_image = pygame.transform.flip(my_image, True, False)
# Display the original and flipped images
game_display.blit(my_image, (0, 0))
game_display.blit(flipped_image, (display_width/2, 0))
pygame.display.update()
# Quit the game
pygame.quit()
```
In the above example, we first load an image using the `pygame.image.load()` method. We then use the `pygame.transform.flip()` method to create a flipped version of the image by passing in `True` as the first argument to indicate that we want to flip the image horizontally. We then display both the original and flipped images using the `blit()` method. Finally, we update the display and quit the game.
pygame.transform.rotozoom用法
`pygame.transform.rotozoom`函数用于旋转并缩放图像。它接受三个参数:
- `surface`:要旋转和缩放的图像。
- `angle`:旋转的角度,以度数表示。正值表示顺时针旋转,负值表示逆时针旋转。
- `scale`:缩放因子。大于1表示放大图像,小于1表示缩小图像。1表示保持原始大小。
该函数返回一个新的旋转和缩放后的图像。
示例:
```
import pygame
pygame.init()
# 创建一个300x300的红色正方形
rect = pygame.Surface((300, 300))
rect.fill((255, 0, 0))
# 旋转45度并放大2倍
rotated_rect = pygame.transform.rotozoom(rect, 45, 2)
# 显示原始图像和旋转后的图像
screen = pygame.display.set_mode((600, 300))
screen.blit(rect, (0, 0))
screen.blit(rotated_rect, (300, 0))
pygame.display.update()
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
```
该示例创建一个红色正方形并将其旋转45度并放大2倍。然后,它在屏幕上显示原始图像和旋转后的图像。
