The InkPicture control provides the ability to place an image in an application and enable users to add ink on top of it. It is intended for scenarios in which ink is not recognized as text but is instead stored as ink.
The InkPicture control can be instantiated by calling the CoCreateInstance method in C++ or by using the New keyword in Visual Basic 6.

The run time user interface for the InkPicture control is a window with an opaque background (single color, picture background, or both) that contains opaque ink.
You can use the InkPicture control to render ink in Microsoft® Windows® 2000, Windows Server 2003, and any edition of Windows XP other than Windows XP Tablet PC Edition. However, you can input ink, accept gestures, or recognize handwriting only under the following conditions:
- Ink can be input and recognized if Windows XP Tablet PC Edition is installed.
- Gestures can be recognized if Windows XP Tablet PC Edition is installed.
- Handwriting can be recognized as text if the handwriting originated elsewhere and if recognizers are present.
If you use Windows 2000, Windows Server 2003, or any edition of Windows XP other than Windows XP Tablet PC Edition, you can assign values to the ambient properties of the InkPicture control and copy and paste ink to other applications, but the value of its InkEnabled property is always False.
Persisted InkDisp objects can be loaded and displayed on all editions of Windows XP (including the Windows XP Tablet PC Edition) and on systems that have only the Windows XP Tablet PC Edition Software Development Kit (SDK) installed. However, the InkDisp objects can be converted to text (recognized) only if Windows XP Tablet PC Edition is installed.
If operations on this control do not succeed the returned error is a legal HRESULT from either the Microsoft Platform Software Development Kit (SDK) or the Tablet PC SDK Automation API. If error conditions are returned, check the returned HRESULT against both.

To improve your application's performance, manually dispose of an InkPicture control when it is no longer needed.
This object implements the IInkPicture COM interface.
