Python OpenCV–resizeWindow()函数

原文:https://www.geesforgeks.org/python-opencv-resizewindow-function/

Python OpenCV 中的 resizeWindow()方法用于将显示图像/视频的窗口调整到特定大小。指定的窗口大小适用于除工具栏之外的图像。这仅适用于创建的具有除 CV_WINDOW_AUTOSIZE 以外的标志的窗口。

语法:cv2.resizewindow(window_name，width，height)

参数:

• 窗口名称:将显示图像/视频的窗口的名称
• 宽度:新窗口宽度(整数型)T3】
• 高度:新窗口高度(整数型)

返回值:不返回任何东西

用于以下示例的图像:

例 1:

蟒蛇 3

# 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:

例 2:

蟒蛇 3

# Python program to explain cv2.resizeWindow() method

# Importing cv2
import cv2

# Path
path = 'C:/Users/art/OneDrive/Desktop/geeks.png'

# Reading an image in grayscale mode
image = cv2.imread(path, 0)

# Naming a window
cv2.namedWindow("Resize", cv2.WINDOW_NORMAL)

# Using resizeWindow()
cv2.resizeWindow("Resize", 700, 200)

# Displaying the image
cv2.imshow("Resize", image)
cv2.waitKey(0)
