Explanation
The IKGetImageFromHdc function retrieves the image from the screen device context and returns it to the image data.
Note: Some components such as a PictureBox, do not always retrieve the height and width of the actual image. In such cases there can be problems with the IKGetImageFromHdc function retrieving the image from the screen device context.
