Moving left and right on the screen

[Benjamin]

Hi all,

I have a pixmap that is 1000 pixels wide and the screen that is 220 pixels wide. What I am trying to do is to write some stuff on this 1000 pixels wide pixmap and move left and right to see that data. So I would initially write all data on this 1000 pixels wide pixmap but I don't exactly know how to implement this left/right scrolling over this pixmap. Does anyone has any idea? I have attached a picture with a description.


Thank youm
Benjamin
