InkEdit and InkPicture
InkEdit and InkPicture provide the ability to capture ink input
from users of Tablet PCs.
The InkEdit control captures and recognizes handwriting and
optionally converts it to text. The InkPicture control captures
signatures, drawings, and other annotations that do not need to be
recognized as text. You can place a background image in an InkPicture
control, and capture and save a user’s annotations to the
picture.
The ink controls are fully functional on Tablet PCs. On other
computers, the InkEdit control behaves like a multiline edit control.
If the Microsoft Tablet PC Software Development Kit (SDK) 1.7 is
installed on the computer, InkPicture controls can accept ink input
from the mouse.
InkEdit control
The InkEdit control on a Tablet PC is like a MultiLineEdit
control that has the added ability to accept ink input. On other PCs,
the InkEdit control behaves as a normal MultiLineEdit control and
cannot collect ink.
On a Tablet PC, the InkEdit control collects ink from a user in
the form of handwriting and can handle single or multiple lines of
text. It also recognizes gestures, which are specific pen strokes that
represent a keyboard action such as backspace, space, or tab. The
InkEdit control can convert ink to text, or leave it as
handwriting.
InkPicture control
The InkPicture control behaves like a Picture control that
accepts annotation. The InkPicture control does not convert ink to
text. You can associate a picture with the control so that the user
can draw annotations on the picture, then save the ink, the picture,
or both. If you want to use the control to capture and save
signatures, you usually do not associate a picture with it.
You might use an InkPicture control to display an image of a
process flow chart or a floor plan of a building, and capture
suggested changes that users enter in the form of ink. Using an image
of a garden, for example, a user could mark trees and shrubs to be
removed and indicate where new plants should be added.
You can save the background image, the ink annotations, or both,
to a file or to a blob.
