The first goal was to display a picture in a defined viewport as a whole series of side by side laid tiles and thus either horizontally or vertically.
The first thought was: OK, this is quite easy, I can take a picture and draw it several times in a loop at the end of the other until the viewport has felt. The problem was that every time if the viewport has changed that new number of repetitions have to be calculated and the pictures must be redrawn.
The second goal was to display the single pictures in their original size or scaled proportionally to the width or height of the viewport. If the original size is chosen, with the viewport resizing only the number of repetitions changes, but if scaled mode is chosen, not only the number but also the positions of the single tiles changes.
The third goal was to allow setting the initial adjustment of the tiles relative to the viewport itself, and to allow changing this adjustment with an offset in the real time. In this point everything becomes a little more complicated.
The second thought was: the DrawingBrush makes fine all the things listed above, but in two directions! It would be great to try forcing the DrawingBrush to draw tiles in just one direction. And the idea was born!
According to the analysis it was quite clear: a new custom control is necessary to encapsulate all the calculations.
