I have a problem I can't think through.
If there are one bitmap and one scroll bar, how can I change the bitmap color by moving the scroll bar.
For example, the scroll bar Max.length = 255.
At the beginning, the scrollbar is on the left and the position = 0, bitmap color is white, as I move the scrollbar the color of the bitmap changes and becomes to black until the scrollbar is on the right side and position = 255. Any one who knows the idea can you please write a sample code. I wish it is clear , Thank you!!
