how can I keep track of changes in a Bitmap in view
Posted on 1998-03-22
Iam facing a problem regarding Bitmap. Actually iam displaying a bitmap on my view. If bitmap's height and width exceeds my view size then, scrollbar will appear. Ok. Now iam providing a pencil using which the user can edit/draw something on the bitmap.
Now, for the bitmaps of bigger size(ie: in which case scrollbar is coming), when user scrolls down and draw something on the bitmap area, how do i keep track of that change in the original bitmap. [iam not able
to keep track of that change, and when redraws that change goes off].
Hope now u got the problem. If u have any idea regarding this, please let me know.
