Python OpenCV – resizeWindow()函数

Python OpenCV 中的 resizeWindow() 方法用于将显示图像/视频的窗口调整为特定大小。指定的窗口大小适用于不包括工具栏的图像。这仅适用于创建的具有除CV_WINDOW_AUTOSIZE 以外的标志的窗口。

Syntax: cv2.resizeWindow(window_name, width, height)

Parameters:

• window_name: Name of the window that will display image/video
• width: New window width (integer type)   
• height: New window height (integer type)

Return Value: It doesn’t return anything

示例 1：

Python3

# Python program to explain cv2.resizeWindow() method
  
# Importing cv2
import cv2
  
# Path
path = 'C:/Users/art/OneDrive/Desktop/geeks.png'
  
# Reading an image in default mode
image = cv2.imread(path)
  
# Naming a window
cv2.namedWindow("Resized_Window", cv2.WINDOW_NORMAL)
  
# Using resizeWindow()
cv2.resizeWindow("Resized_Window", 300, 700)
  
# Displaying the image
cv2.imshow("Resized_Window", image)
cv2.waitKey(0)

输出：
