SWIGMapscript: layerObj.queryByPoint using point in image coordin ates

[GeoIT]

Dear experts,
As stated in SWIGMapscriptReference layerObj.queryByPoint needs a point in
map coordinates to work. This seems to be true because it does not find any
object if I use a point in image coordinates even if using a very large
buffer.

So how do I transform a point from image coordinates to map coordinates ? Is
there another way to do a query by a point directly using a point in image
coordinates ?

Many thanks in advance !

regards
Andreas Paukner-Ruzicka
