Screen Capture

From IronPython Cookbook

Screen Capture

The below code explains how to capture screen using a simple IronPython code. The Code is a simple windows forms application. The heart of the code is in cmdcaptureclicked function. Here Screen class is used to get the screen width and height. Using Bitmap class we grab the image and buffered into a temporary memory.

When run, it minimizes itself and displays a screenshot in a PictureBox:

import clr

clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")

from System.Drawing import Bitmap, Graphics, Point, Size
from System.Windows.Forms import (
    Application, Button, Form, FormWindowState,
    PictureBox, Screen
)

frm = Form(Text="Capture Screen")
frm.ClientSize = Size(290, 288)

pb = PictureBox()
pb.Location = Point(0, 0)
pb.Size = Size(100, 50)
frm.Controls.Add(pb)

def cmdcaptureclicked(sender, args):
    frm.WindowState = FormWindowState.Minimized
    bmp = Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)
    g = Graphics.FromImage(bmp)
    g.CopyFromScreen(0, 0, 0, 0, bmp.Size)
    g.Dispose()
    
    pb.Image = bmp
    pb.Size = bmp.Size


cmdcapture = Button()
cmdcapture.Text = "Capture Screen"
cmdcapture.Location = Point(169, 249)
cmdcapture.Size = Size(110, 30)
cmdcapture.Click += cmdcaptureclicked
frm.Controls.Add(cmdcapture)

def main():
    Application.EnableVisualStyles()
    Application.Run(frm)


if __name__ == "__main__":
    main()
