// 以下是一个用Python语言编写的自动截屏程序代码,要求1秒截屏一次并保存:
import time
import os
import pyautoguidef screen_shot():
# 设置保存的文件夹
dir_name = "screenshots"
if not os.path.exists(dir_name):
os.mkdir(dir_name)
while True:
# 截图
curr_time = time.strftime("%Y-%m-%d_%H_%M_%S")
pic_name = curr_time + ".png"
pic_path = os.path.join(dir_name, pic_name)
pyautogui.screenshot(pic_path)
# 设置间隔时间
time.sleep(1)if __name__ == '__main__':
screen_shot()

在TK界面程序中添加一个”自动截图“的按钮和”停止截图“按钮,点击“自动截图”后每5秒自动调用截图函数,点击“停止截图”后停止调用截图函数
实现该功能需要使用Python的`tkinter`和`PIL`库。
首先,我们需要创建一个基本的界面框架,包含“自动截图”和“停止截图”两个按钮。
```python
import tkinter as tk
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.master = master
self.pack()
self.create_widgets()
def create_widgets(self):
self.auto_screenshot_button = tk.Button(self)
self.auto_screenshot_button["text"] = "自动截图"
self.auto_screenshot_button["command"] = self.auto_screenshot
self.auto_screenshot_button.pack(side="left")
self.stop_screenshot_button = tk.Button(self)
self.stop_screenshot_button["text"] = "停止截图"
self.stop_screenshot_button["command"] = self.stop_screenshot
self.stop_screenshot_button.pack(side="left")
def auto_screenshot(self):
pass
def stop_screenshot(self):
pass
root = tk.Tk()
app = Application(master=root)
app.mainloop()
```
现在,我们需要实现`auto_screenshot`和`stop_screenshot`函数。`auto_screenshot`函数需要每5秒自动截图,并将截图保存到指定的文件夹中。我们可以使用`PIL`库的`ImageGrab`模块来实现截图功能。同时,我们需要在`auto_screenshot`函数中创建一个定时器,以实现每5秒截图的功能。当用户点击“停止截图”按钮时,我们需要停止该定时器。
```python
from PIL import ImageGrab
import time
import threading
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.master = master
self.pack()
self.create_widgets()
self.is_screenshotting = False
def create_widgets(self):
self.auto_screenshot_button = tk.Button(self)
self.auto_screenshot_button["text"] = "自动截图"
self.auto_screenshot_button["command"] = self.auto_screenshot
self.auto_screenshot_button.pack(side="left")
self.stop_screenshot_button = tk.Button(self)
self.stop_screenshot_button["text"] = "停止截图"
self.stop_screenshot_button["command"] = self.stop_screenshot
self.stop_screenshot_button.pack(side="left")
def auto_screenshot(self):
if not self.is_screenshotting:
self.is_screenshotting = True
self.screenshot_thread = threading.Thread(target=self.screenshot_loop)
self.screenshot_thread.start()
def stop_screenshot(self):
if self.is_screenshotting:
self.is_screenshotting = False
def screenshot_loop(self):
while self.is_screenshotting:
# 截图
im = ImageGrab.grab()
# 保存截图
im.save("screenshot_{}.png".format(time.time()))
# 等待5秒
time.sleep(5)
root = tk.Tk()
app = Application(master=root)
app.mainloop()
```
在这个版本的代码中,我们使用了一个`is_screenshotting`变量来记录当前是否正在截图。当用户点击“自动截图”按钮时,我们创建一个新的线程来执行`self.screenshot_loop`函数,该函数实际上就是一个死循环,每次循环中都会执行截图和保存截图的操作,并等待5秒。当用户点击“停止截图”按钮时,我们将`is_screenshotting`变量设置为`False`,从而停止循环。注意,在`auto_screenshot`函数中,我们需要检查`is_screenshotting`变量,以避免创建多个线程。
用VB6.0生成一个支持扩展屏截图的截图工具
下面是一个使用VB6.0编写的支持扩展屏截图的截图工具示例。该程序使用Windows API函数和VB6.0自带控件实现屏幕截图功能,并支持多个显示器。
1. 创建一个新的VB6.0项目,并添加以下控件:一个PictureBox控件,一个CommandButton控件和一个Label控件。
2. 在代码窗口中插入以下代码:
```
Option Explicit
Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, lpRect As RECT) As Long
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function ReleaseDC Lib "user32" (ByVal hwnd As Long, ByVal hdc As Long) As Long
Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long
Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type
Private Sub Command1_Click()
Dim hWnd As Long, hDC As Long, result As Long
Dim rect As RECT
Dim picWidth As Long, picHeight As Long
'获取当前活动窗口的句柄
hWnd = GetForegroundWindow()
'获取窗口的位置和大小
result = GetWindowRect(hWnd, rect)
'计算截图的宽度和高度
picWidth = rect.Right - rect.Left
picHeight = rect.Bottom - rect.Top
'创建图像对象并绘制截图
Picture1.AutoRedraw = True
Picture1.Width = picWidth / Screen.TwipsPerPixelX
Picture1.Height = picHeight / Screen.TwipsPerPixelY
hDC = GetDC(hWnd)
result = BitBlt(Picture1.hDC, 0, 0, picWidth, picHeight, hDC, 0, 0, vbSrcCopy)
result = ReleaseDC(hWnd, hDC)
Picture1.AutoRedraw = False
'显示截图的宽度和高度
Label1.Caption = "Width: " & Picture1.ScaleWidth & " Height: " & Picture1.ScaleHeight
End Sub
```
3. 在窗体的Load事件中添加以下代码,以将PictureBox控件设置为自动换行和自动大小:
```
Private Sub Form_Load()
Picture1.AutoSize = True
Picture1.BorderStyle = vbBSNone
End Sub
```
4. 运行程序并单击CommandButton控件来进行截图。截图将显示在PictureBox控件中,并且Label控件将显示截图的宽度和高度。
注意:此示例代码只提供了基本的截图功能,并没有包含保存截图或支持多个显示器的完整代码。如果您需要实现更高级的截图功能,请参考Windows API文档和VB6.0开发文档以获取更多信息。
