hai

i started to create my own map application in j2me so i require the zooming functionality
i have an idea of how zooming is done in map applications but if i draw a path from a place to other how do i implement the same in next zoom level because i ll have 4 zoomed images of previous level say i m in zoom 16 i n zoom 17 i ll have 4 images and how do i move zoomed images through the direction keys because they are 4 different images
