python - 图像查看器python 3.5中显示的图像名称错误

Question

当我在图像查看器中打开图像时，显示的图像名称错误(与加载的图像不同)。原始图像='image.PNG'，图像查看器中的名称='tmpy4uvijg0.BMP'(新名称始终会更改，见下图)

from PIL import Image
imName='image.PNG'
try:
    with Image.open(imName) as im:
        print(imName)
        im.show()
except IOError:
    pass

image.png new image

我做错了什么？为什么名字不一样？

Answer 1

这是因为 show 方法将图像保存到临时文件中，如文档中所述:

Displays this image. This method is mainly intended for debugging purposes.

On Unix platforms, this method saves the image to a temporary PPM file, and calls the xv utility.

On Windows, it saves the image to a temporary BMP file, and uses the standard BMP display utility to show it (usually Paint).

:param title: Optional title to use for the image window, where possible.

:param command: command used to show the image

您可以尝试通过在要显示的参数中传递字符串来更改标题。
