[mapserver-users] Problem with Rect in referencemap to show "extent" of map

[Giorgio Volpe <giorgio@nauta.it>]

The demo mapreference shows a nice rectangle to outline the extent of
the map.

With some particular image the rectangle disappear ... does anybody
knows which is the problem with this?
A problem of number of colors? Image type?

(I'm using all gif images)
