[udig-devel] How to calculate a translated point with his original gps c

[wouaco@xxxxxxx]

Hi,
In my jpg/jgw import plugin, users can click on a point on an image of which
they know gps coordinate in a way to calculate the UTM upper left pixel
coordinate for the world file...
I have the code to convert GPS coordinate to UTM but i don't know how
translating the gps coordinate with pixel coordinate of the reference point.

Could you help me please ?
PS: sorry if my english is bad...
