One of the aims of Metview 4 is to utilise the new features of Magics++. This requires some icons to be updated, specifically the visual definition icons such as Contouring and Coastlines. In order not to interfere with Metview 3's existing icons, Metview 4 defines a new set. These icons look the same as the old ones, but have some different parameters available. Metview 3's icons continue to work as normal (with some possible changes in behaviour), but they will appear slightly greyed out. The following screenshot shows this difference.
Metview 4 will not allow you to directly create new instances of the 'old' icons, but you will find the new ones in the desktop drawers and in the New Icon desktop menu.

Instead of a single output function, Metview 4 uses a set of functions to specify the desired output format, one for each type: ps_output, png_output, etc. One way to see the possible parameters for these functions is to type the appropriate function name in the Macro Editor and press F5 for an interactive help tool.
