wrong with coordinate conversion

[temiz]

hello

For using reference map with php mapscript, I have developed
a formula to convert image coordinates to map coordinates.
But there seems to be something wrong with it.

here is the formula:
"map_coord of a clicked point = (map_maxx - map_minx) *
image_click_ccord / image_width"

what am I doing wrong ?

kind regards

Ahmet Temiz
