SharpAreaPicker

A (WinForms) .NET plugin library to add snipping dialog to your project

How to use It

1. Download the latest version of SharpAreaPicker.dll;
2. Create a new Windows Forms project on your Visual Studio (Community 2017 is the version I use). It has to be pointing to version 4.5.2 or higher of .Net Framework;
3. Go to solution explorer, right click references and choose add reference. Then under the Assemblies tab, click on the search button and add a reference to the SharpAreaPicker.dll You just downloaded;
4. Now, You can use get a snip of the screen like:

Image img = AreaPicker.screenshot(this);
if (img != null)
{
   /*
     img is your screenshot, use It
   */
}

Note: By passing the caller form to the screenshot function, It will be automatically minimized when the snipping dialog comes up.

How the user is supposed to use It

The dialog lacks on instructions, but It's really simple to understand. The AreaPicker dialog is a resizable Form, without a ControlBox (3 common buttons of the top right), that can be dragged with the mouse. It has a context menu that You can bring up by right clicking the dialog, with two items: Capture, which will close the dialog and return the screenshot, and cancel, which will close the form and return null.

"Capture" can be fired by return/enter Keypress as well as cancel will be invoked by pressing the ESC key.
