the options on the tab.
Setting Style Properties for Layers
You can specify properties that control how data appears on a map. For
example, you can specify the display (scale) ranges at which a layer is visible,
the line color, and add labels to the map features. You can also set up a theme,
which displays the data in varying styles to indicate different values in the
data.
Note
Raster layers have different style properties from vector layers. For more
information, see “Setting Style Properties for Raster Layers” on page 163.
When specifying the style properties for a layer, you are setting up one or
more
style sets
. Each style set has a display range and at least one style that
controls how the data displays. By default, there is only one style set per
layer, but you can add more style sets to display the data differently
depending on the current scale. For example, you could create one style set
to display roads with thick lines when you zoom in, and create a second style
set that displays roads with thin lines when you zoom out.
