Question

我是Pyglet（和stackoverflow）的新手，似乎无法找到如何调整图片大小。

＆＃39; pipe.png＆＃39;是我试图调整大小的图像。

使用此代码时，由于窗口尺寸太小，图像未完全显示。

我想调整图像的大小，使其适合窗口内部。

＆＃39; pipe.png＆＃39;的当前大小是100x576。

import pyglet

window = pyglet.window.Window()

pyglet.resource.path = ["C:\\"]
pipe = pyglet.resource.image('pipe.png') 
pyglet.resource.reindex()  

@window.event                    
def on_draw():
    window.clear()
    pipe.blit(0, 0)

pyglet.app.run()

修改

我最终在这里找到了答案：

http://pyglet.org/doc-current/programming_guide/image.html#simple-image-blitting

解决方案是：

imageWidth = 100
imageHeight = 100

imageName.width = imageWidth
imageName.height = imageHeight

这将调整为图像大小以显示为100x100

遇到这个老人，所以对于任何孤独的游侠来说，就像我一样。更改.width和.height在很多情况下（或者在所有这些日子里都没有用）？

为了成功更改图像分辨率，您需要修改它的.scale属性。

以下是我用来调整图片大小的代码片段：

from pyglet.gl import *

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST)

image = pyglet.image.load('test.png')
height, width = 800, 600 # Desired resolution

# the min() and max() mumbo jumbo is to honor the smallest requested resolution.
# this is because the smallest resolution given is the limit of say
# the window-size that the image will fit in, there for we can't honor
# the largest resolution or else the image will pop outside of the region.
image.scale = min(image.height, height)/max(image.height, height)), max(min(width, image.width)/max(width, image.width)

# Usually not needed, and should not be tampered with,
# but for a various bugs when using sprite-inheritance on a user-defined
# class, these values will need to be updated manually:
image.width = width
image.height = height
image.texture.width = width
image.texture.height = height
