VB

hiii all,

I have converted the text say 'abc' into my handwriting .... for this i have called the samples of a, b,c from my sql database, and finally render them one by one using Ink object , now finally they are render on picture box.. means i have three strokes now... i want to do clipp operation on them ... I have Inkoverlay object which contains the each stroke information (like stroke count etc) Now when i see the properties of inkoverlay of the rendered strokes it shows only one count of stroke although i have rendered three strokes on picture box now how can i combine all the strokes and preserve them in Inkoverlay class ... iam not able to get bounding boxes of each strokes. i have the code snippet as below

Dim mink As New Ink
            mink.Load(mByte)
            boundingBox = mink.Strokes.GetBoundingBox

dim bytearr as new arraylist

bytearr.Add(mByte)('iam reading mbyte from sqldatabase for ecah character one by one ')

byteink.Load(bytearr(0))
       Dim byteink1 As New Ink
       byteink1.Load(bytearr(1))
       'Next
       'byteink.Load(mByte)

       Dim rect1 As Rectangle
       Dim rect2 As Rectangle
       Dim rtf As Rectangle

       ' For Each Stroke In byteink.Strokes
       rect1 = byteink.GetBoundingBox
       rect2 = byteink1.GetBoundingBox
       ' Next
       rtf = New Rectangle(rect1.X + rect1.Width, rect2.Y, rect2.Width - rect1.X - rect1.Width + rect2.X, rect2.Height)
       ' rtf = New Rectangle(rect1.X, rect1.Y, rect2.Left - rect1.X, rect1.Height)
       mink.Clip(rtf)

here mink contains the information of stroke on the basis of mbyte so each time mink.strokes count appears as 1 only .... but i want all the strokes information aftr rendering all them on Picture box


so please help me out how can i get the information of all the strokes on picture box into single Inkoverlay object


with regards
