here is some codes that read the data from a textfile '"pose1.txt".  please help !

1. float zoom;
2. // A vector to store the offset from the center
3. PVector offset;
4. // The previous offset
5. PVector poffset;

35.   scale(zoom);
36.   // The offset (note how we scale according to the zoom)
37.   translate(offset.x/zoom, offset.y/zoom);
