Figure 7.5: The Load Data - Viewer panel that appears if you open the viewer without any infile specified, or if you use the Data:Open menu or Open icon. You can see all available files (e.g. images and MS) in the current directory that could be loaded into the viewer.

_________________________________________________________________________________________

You can use the Load Data - Viewer GUI to interactively choose images or MS to load into the viewer. An example of this panel is shown in Figure 7.5. This panel is accessed through the Data:Open menu or Open icon of the Viewer Display Panel. It also appears if you open the viewer without any infile specified.

Selecting a file on disk in the Load Data panel will provide options for how to display the data. Images can be displayed as:

raster image,
contour map,
vector map,
marker map.

You can also enter a ’Lattice Expression Language’ (LEL) expression in the box provided (§ 6.1.3). The images used in the LEL expression should have the same coordinates and extents).

A MS can only be displayed as a raster.
