Represents the area that the InkRecognizer object uses and in which ink can be drawn. The area is known as the recognizer guide.
Assembly: IAWinFX (in IAWinFX.dll)
The can consist of rows and columns, and gives the recognizer a better context in which to perform recognition. For example, you can draw horizontal lines on a user's screen, almost like a ruled piece of paper, that show where inking should occur (this type of guide would consist only of rows without columns). If a user writes on the lines, instead of some arbitrary space, recognition accuracy improves. For example, letters such as "t" and "I" are more easily recognized when a guide is used to give context to the ink.
The specifies the boundaries where ink can be drawn by defining two rectangles; the drawn box and the writing box. The boundaries of the drawn box are visual cues, and the boundaries for the writing box are invisible. Together, they specify where writing can take place. The user normally writes within the boundaries of the visible lines of the drawn box. The drawn box is specified by the DrawnBoxTop, DrawnBoxLeft, DrawnBoxBottom, and DrawnBoxRight properties. These properties are for the recognizer's use only. Setting them does not, by itself, draw visual clues on the display. You must draw the visual clues by using the application or the control.
The writing box is larger than the drawn box and provides the users a margin of error if they draw ink outside the lines of the drawn box. The writing box is specified by the WritingBoxTop, WritingBoxLeft, WritingBoxBottom, and WritingBoxRight properties.
In addition to drawing lines or rules on the screen that show users where to write, it is also possible to draw cells on the screen in which characters or words are written. This is called boxed input and is useful with some East Asian languages. To determine if the recognizer is capable of boxed input, call the Capabilities property of the InkRecognizer object.
By default the guide has all property values set to 0, which means there is no guide. You must use the properties of the object to set the guide.
The following sets all of the values in the simultaneously.
double guideBoxTop = 0; double guideBoxBottom = 50; double guideBoxLeft = 0; double guideBoxRight = 600; const int WRITINGBOXMARGIN = 10; // Find the midline of the guide box. double midline = (guideBoxBottom - guideBoxTop) / 2 + guideBoxTop; theGuide.Rows = 1; theGuide.Columns = 0; theGuide.Midline = midline; theGuide.WritingBoxLeft = guideBoxLeft - WRITINGBOXMARGIN; theGuide.WritingBoxTop = guideBoxTop - WRITINGBOXMARGIN; theGuide.WritingBoxRight = guideBoxRight + WRITINGBOXMARGIN; theGuide.WritingBoxBottom = guideBoxBottom + WRITINGBOXMARGIN; theGuide.DrawnBoxLeft = guideBoxLeft; theGuide.DrawnBoxTop = guideBoxTop; theGuide.DrawnBoxRight = guideBoxRight; theGuide.DrawnBoxBottom = guideBoxBottom;
