I am trying to develop a ink box in C# that can be drawn in so a person can
trace a letter (e.g the letter "a") however, even when I try to bound the
box, if the person is holding down the mouse button and goes beyond the box,
ink will continue to be drawn even though the user cannot see it. In case
that not entirely clear, its more or less like you are writing on a piece of
paper and you pen slips off of it, on paper you stop writing, in my program
it continues to write. Even worse is that when I go to recognize what they
have written all of the ink outside of the box will be recognized (i.e. if
they wrote the letter "a" almost completely outside the box, it will still be
recognized as the letter "a"). Can anyone help me out?

Thanks!

You need to clip the ink. But you need to decide how you want this to work.
If they drag outside the line and drag back in, should that be considered
two separate strokes? Or should the points be constrained to the edge of the
bounding box and the stroke be treated as a single stroke?

You can achieve the latter using RealTimeStylus which has a bit of a
learning curve but is a very powerful tool for accessing and manipulating
the stylus data streams.

If you just want to clip the ink (which may result in a "broken" stroke
which appears as two strokes) you can use the Clip method of the Strokes
class prior to sending the strokes to the recognizer.

I am basically trying to not even allow them to write beyond the bounds of
the box if there is a way to do that and if there isn't I would prefer the
recognizer either disregard all ink outside the box or do as you said and
count it as two separate strokes so the letter recognition comes up incorrect.

The only way to stop it is to use RealTimeStylus. Otherwise just allow it
and clip it before you send it to the recognizer and then it will be treated
as two strokes.

Strokes allStrokes = myOverlay.Ink.Strokes;
allStrokes.Clip(boundsInInkSpace);

recoContext.Strokes = allStrokes;

RecognitionStatus recoStatus;
RecognitionResult result = recoContext.Recognize(out recoStatus);
