GeoPlan Properties And Themes dialog - Visual page

This page controls visual effects on the GeoPlan window such as selection colour, hill shading settings, theme keys, and theme graphic quality.

This page is opened by right-clicking the GeoPlan and selecting Properties & Themes, then clicking the Visual tab.

Settings are used only for the current GeoPlan view. If the current GeoPlan window is closed, the settings will be lost (but see Network Editing Properties - Save Options dialog).

Description

Selection Colours

This section is used to change the selection colour of objects displayed in the GeoPlan window.

Network

Selection colour is used to highlight all selected objects in network views.

Properties

Selection colour is used to highlight objects for which properties are viewed. When the properties for a network object are displayed, the object will be momentarily highlighted using this colour.

GIS Layer

Selection colour is used to highlight objects found using the Find on GeoPlan button on the Find Network Objects dialog - GIS Find page.

Hill shading

You can use hill shading to emphasise the contours of a ground model displayed on the GeoPlan Window. Hill shading simulates a light source (the sun) which you can point towards your model:

from any direction around the horizon
from any angle between horizontal (0°) and directly overhead (90°).

You can also exaggerate the vertical scale to make contours stand out more clearly.

The best effects from hill shading need to be found by trial and error, and will vary depending on the ground model.

On	Switches hill shading on and off.
Azimuth	For setting the horizontal angle. 0° means the light source is pointing from the top of the view.
Altitude	For setting the vertical angle. 90° is directly overhead.
Vertical exaggeration	For choosing the best effect.

Misc

Show ground level in coordinates panel	If checked, displays ground level on the Status Bar when there is a Ground Model loaded in the GeoPlan. See Displaying Ground Model Height on the GeoPlan.
Show triangles in TIN groound models	If checked, displays the outlines of the underlying triangles that make up a TIN ground model.
Always show selected objects	If checked, shows selected objects on the GeoPlan even when they would not normally be, for example if the zoom level did not normally include them.
Show base scenario ghosts	If checked, turns on the display of objects present in the base network but not in the current scenario.

Theme Keys

Change themes shown in key window

Allows you to specify en masse which of the layer themes are to be shown in the Thematic Key window.

Change themes shown in print legend

Allows you to specify en masse which of the layer themes are to be shown in the printed legend.

Hide Theme layers without objects

When checked, indicates that if no object of a particular type exists in the network, the legend for it (of the type symbol - object type) will be hidden in the Thematic Key and printed legend.

Graphic Quality

This slider governs the switching between two different types of Microsoft Graphics Device Interface, GDI and GDI+ (see Options - General Page for other GDI+ settings) which are responsible for representing graphical objects and transmitting them to output devices such as monitors and printers. Compared to GDI, which draws faster, GDI+ takes longer to draw but it has the advantage of supporting anti-aliasing, transparency, gradient shading and modern graphics file formats.

The switch is based on the number of objects to be drawn and the slider adjusts the threshold. Middle values for the slider should be preferred as these represent a trade-off between speed and graphic quality.

Note that in GDI mode, lines or symbols with very low visibility will not be drawn. For large networks, when displaying themes that use a range of visibility settings, set the Graphic Quality to a higher setting to view transparency effects (may affect drawing speed).

Enable/Disable Multiple Themes

This lets you disable all the themes that have been set up for the type(s) of object listed. Examples: all themes set up for nodes, or all themes set up for live data symbols.
