无法在Tkinter中显示图像 [英] Cannot Display an Image in Tkinter

问题描述

当我运行程序时，画布会显示，但Image不显示。

When I run the program the canvas shows up but the Image does not.

canvas = Canvas(frame, width = 128, height = 128, bg= 'white')
    image_data = Image.open('NoArt.gif')
    ppm_f = ImageTk.PhotoImage(image_data)
    canvas.create_image(0, 0, image = ppm_f, anchor = NW)
    canvas.pack(side=BOTTOM)

任何想法??

PS。

我有
PIL版本1.6，
python 2.6和
python 2.6附带的Tkinter版本

I have PIL ver 1.6, python 2.6, and The Version of Tkinter that comes with python 2.6

推荐答案

好的，我想通了。显然，由于python处理垃圾处理的方式，图片才会被删除。需要在全局范围内引用图像。这是我最终使用的工作代码：

Ok, I figured It out. Apparently due to the way that python deals with garbage disposal the pictures just get erased. A reference to the image in the global scope is required. This is the working code I eventually ended up using:

self.photo = PhotoImage(file="noart.ppm")
    self.Artwork = Label(self.frame, image=self.photo)
    self.Artwork.photo = self.photo
    self.Artwork.pack()

self.Artwork.photo = self.photo 是重要的部分。它确保显示图像。

that self.Artwork.photo = self.photo is the important part. It ensures that the Image will be shown.
