python的ImageTk.PhotoImage坑怎么解决(ImageTk.PhotoImage,python,开发技术)

接下来，请跟着小编一起来学习吧！

Exception in Tkinter callback
Traceback (most recent call last):
File "E:\Anaconda3_files\lib\site-packages\PIL\Image.py", line 2515, in fromarray
mode, rawmode = _fromarray_typemap[typekey]
KeyError: ((1, 1, 3), '<f8')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "E:\Anaconda3_files\lib\tkinter__init.py", line 1705, in call__
return self.func(*args)
File "D:\Junior Spring\Digital Image Processing and Experiment\数字实验备份\结课实验\ImgProcessing.py", line 806, in Sobel_Sharpening
image = ImageTk.PhotoImage(Image.fromarray(img))
File "E:\Anaconda3_files\lib\site-packages\PIL\Image.py", line 2517, in fromarray
raise TypeError("Cannot handle this data type")
TypeError: Cannot handle this data type

这里有个很关键的信息：Cannot handle this data type

1.如果没有安装PILLOW插件，请安装插件，使用 “pip install PILLOW”命令安装即可

2.生成PhotoImage对象：

fromPILimportImageTk

img=Image.open(filePath)

img=ImageTk.PhotoImage(img)

2.PhotoImage显示问题：显示空白框，大小是图片的真实大小

ifos.path.exists(filePath)andos.path.isfile(filePath):

iffilePathinimgDictandimgDict[filePath]:

returnimgDict[filePath]

img=Image.open(filePath)

img=ImageTk.PhotoImage(img)

imgDict[filePath]=img

returnimg
