[maplab-users] Error in msSaveImage(): GIF Output is not available

[patruno]

Thanks a lot for your suggestion.
I changed  MS_GIF to MS_PNG and now I can launch the preview.
(Does MS_JPG work too?)

Now the problem is the Rosa applet.
Using maplab-2.0rc2 the Rosa applet appears completely blank No map and no buttons appear in the preview page.
But if I disable the applet, everything works well. The map appears and I can also browse it using the zoom-in and zoom-out functions.

Using maplab-2.0rc3 I can preview my mapfile in the applet. The problem is when I try to zoom-in and zoom-out the map.
When I select a square to zoom in, the applet zoom on a wrong area. Why? And when I zoom-out somewhere, the map always return back 
to the  starting point.

(I have the same problem even if I disable the applet).

Thanks again in advance

Vincenzo
