Screen shot using JavaScript

**Roxy_jacob** · 03-12-2009

Hi,

I am having a problem with the coding of the .NET programming language using the JavaScript. I am working on the project that will take the screen shot of the screen's particular area using the JavaScript, but i am unable to do so. For making my project working i used Graphics.CopyFromScreen functionality of the .NET, but could not find to the result.

Thank you

What i got from the description is that you are interested in taking the shot of the screen's particular area using the JavaScript.For that i will suggest you to use ActiveX control which is known as the ActiveScreen for capturing the particular screen area.

Here is the code for the same.

Code:

var as=new ActiveXObject("ActiveScreen.Capturer");
as.CaptureScreen();
var fs=as.SaveToFile("Screenshot1.jpg");
WScript.Echo("Size of the image = " + fs.toString() + "\r");

This code will capture the complete screen and save it to the other format. Hope that this will help you.

Thanks

Hi there,

I am having the same problem regarding the capturing of the screen's area and searched a lot and finally got the answer. Hope that the solution which i got might be help you also so try your luck for the same. The code will capture the particular area of the screen defined by the user. Use this to resolve your issue. This will save the file in the .png format

The code is given below:

Code:

var as=new ActiveXObject("ActiveScreen.Capturer");
as.CaptureOval(100,50, 400);
var fs=as.SaveToFile("Capture.png");
WScript.Echo("Size = " + fs.toString() + "\n");

Hello,

I hope this will disappoint you that it can not be possible with the JavaScript because JavaScript can not uses binary stream. If you want to make rendering tests then you use instantiating the target browsers with the host environment. Thats all i know about the screen shot taking process. So i am hoping that this will you to finalize your project.

Thanks
