image coordinates to geographic coordinates

[temiz]

hello

Despite all my  efforts, I can not correctly convert image coordinates
to geographic coordinates (UTM).
 what might  the javascript code be ?

here is my code:
   x_pct = (evt.clientX / width);
    y_pct = 1 - (evt.clientY / height);
    x_map = ext0 + ( (ext2 - ext0) * x_pct);
    y_map = ext1+ ( (ext3 - ext1) *  y_pct);


thanks in advance

Ahmet Temiz
