I solved the same problem by writing my own image viewer widget. See:
http://giv.sourceforge.net/gtk-image-viewer/
It provides the functions:
void gtk_image_viewer_canv_coord_to_img_coord (GtkImageViewer * self,
double cx,
double cy,
double * imgx,
double * imgy);
void gtk_image_viewer_img_coord_to_canv_coord (GtkImageViewer * self,
double imgx,
double imgy,
double * canvx,
double * canvy);
to convert between canvas (callback) and image coordinates, no matter what
your zoom and scroll positions are.
That said, perhaps someone else can answer you regarding ImageView.

Dov
