显示带有图形视图小部件的图像 [英] showing an image with Graphics View widget

问题描述

我是 qt 设计器和 python 的新手.我想创建一个应该显示图像的简单项目.
我使用了Graphics View"小部件，并将其命名为graphicsView".我写了这些函数:

I'm new to qt designer and python. I want to created a simple project that I should display an image.
I used "Graphics View" widget and I named it "graphicsView". I wrote these function:

def function(self):
    image=cv2.imread('C:/Users/Hamid/Desktop/1.jpg',1)
    self.show_frame_in_display(image)

def show_frame_in_display(self,frame):
    image = QImage(frame, frame.shape[1], frame.shape[0],
                  frame.strides[0], QImage.Format_RGB888)
    self.graphicsView.setPixmap(QPixmap.fromImage(image))

但它给出了这个错误:

File "C:/Users/Hamid/Documents/untitled/hamid.py", line 54, in show_frame_in_display
self.graphicsView.setPixmap(QPixmap.fromImage(image))
AttributeError: 'QGraphicsView' object has no attribute 'setPixmap'

我该怎么办?谢谢.

推荐答案

您也可以使用 QtGui.QLabel 来显示图像，方式如下:

You can use a QtGui.QLabel to display images as well, this way:

label_Image = QtGui.QLabel(frame)
image_path = 'c:\image_path.jpg' #path to your image file
image_profile = QtGui.QImage(image_path) #QImage object
image_profile = image_profile.scaled(250,250, aspectRatioMode=QtCore.Qt.KeepAspectRatio, transformMode=QtCore.Qt.SmoothTransformation) # To scale image for example and keep its Aspect Ration    
label_Image.setPixmap(QtGui.QPixmap.fromImage(image_profile)) 

在你的原始代码中实现上面的代码:

Impplementing the above code in your original code:

def function(self):
    image_path='c:\image_path.jpg' #path to your image file
    self.show_frame_in_display(image_path)

def show_frame_in_display(self,image_path):
    frame = QtGui.QWidget() #Replace it with any frame you will putting this label_image on it
    label_Image = QtGui.QLabel(frame)
    image_profile = QtGui.QImage(image_path) #QImage object
    image_profile = image_profile.scaled(250,250, aspectRatioMode=QtCore.Qt.KeepAspectRatio, transformMode=QtCore.Qt.SmoothTransformation) # To scale image for example and keep its Aspect Ration    
    label_Image.setPixmap(QtGui.QPixmap.fromImage(image_profile))
