Preview mode is activated through the View->Preview Mode menu or by pressing the button on the left bar. In the preview mode the loaded layers are visible in the order they were added, while the raster layers are always "at the bottom", i. e. visible in the background (Fig. 5). You can change the order of displaying layers (Layers->Move Up/Down, or buttons and in the Layer Manager tab), and hide them (icon ). The loaded layer can also be centered (button ) or removed from the list (button ). These options are also available in the edit mode.
Fig. 5. Program in the preview mode. Loaded raster layer and vector layers.
In the preview mode, the image visible in the main program window can be moved by pressing the left mouse button (the cursor changes to ), and change its scale with the mouse wheel or in the drop-down list on the top bar. At the same time, the current cursor position is displayed in the status bar: in meters and degrees, and if a raster image containing elevation data has been loaded, the height in m a.s.l. is also displayed. Moreover, in the preview mode you can find the scale in [km] or [m] in the bottom left corner of the image (map), and a wind rose in the upper right corner. After hovering over a given vector shape on the map, a hint window with the name of the object will appear just below the mouse cursor. Also you can measure a distance in straight line from any point using mouse (Tools->Measure, button ). The result will appear at the status bar.
Fig. 6. Preview for image export to EMF/WMF file.
In the preview mode, you can export your work result to vector Windows metafiles (EMF, WMF) by choosing an option Map->Export to Image or pressing the button on the top bar, and then selecting the area to be exported with the mouse (the cursor will change to "cross"). The export preview window will appear (Fig. 6). The image in the export preview (i. e. the map) contains automatically matched meridians and parallels, and legend elements defined in the layer attributes. Meridians, parallels, and map borders (axes) can be turned off in the Format->Grid and Format->Axes menu, respectively.

The program also enables a detailed formatting of the legend area by the option available in the Format->Legend... menu. This option allows you to change the position of the legend, set the number of columns in which the legend elements are arranged, and change the visibility of these elements, as well as edit the caption (Fig. 7). After closing the export preview window, the program restores the previous view of the preview mode. The visible map image can be saved to a file by choosing File->Save or the button .
Fig. 8. Print preview window.
Similarly, the option of exporting the selected area to a printer works by calling the Map->Export to Printer menu or by pressing the button . The print preview window (Fig. 8) allows you to change the printer as well as the page format and orientation (button ). Moreover, the edges of the image (map) can be snapped to the width of the page (menu Format->Fit to Page) or centered on the page (Format->Center in Page). The printing process is started by pressing the button .
Fig. 9. 3D view window.
Raster data and some of vector data, in particular objects of varied elevation, can be exported to a 3D view. Choose the menu option Map->Export to 3D View or press the button on the top bar and select the area (object) to be exported with the mouse cursor. The export preview (Fig. 9) works like a typical 3D object viewer, with options to rotate and zoom in/out.Contents
