Hi
I am using SunoneStudio4ME with MIDP 1.0 Currently i am getting a map from TigerDatabase by giving Latitude and Longtitude and converting the image to PNG format and displaying in the emulator. I want to know the pixel values for the Image displayed in the device. Is there any algorithm to convert the Latitude to Pixel.

I think thats going to depend on the map projection, but for small areas, I would expect a linear interpolation to work. How are the boundaries of the map specified?
