Area Styles
Using the Area Styles panel users can configure how areas of a given type will be displayed in Global
Mapper. Area fill, border style and color can be modified on a type-by-type basis. The Show Labels for Areas
of This Type option allows users to turn area labels off on a type-by-type basis.
Area Types are shown in the Global Mapper Area Types table. Tables showing the Global Mapper Fill
Patterns and Border Styles follow the Area Types table.
Global Mapper recognizes five field attributes as containing information for the display appearence of an Area
Type. They are:
GM_TYPE=
BORDER_COLOR=
BORDER_WIDTH=
BORDER_STYLE=
FILL_COLOR=
FILL_STYLE=
The "FILL_ALPHA=" field attribute is recognized by Global Mapper to set an Area Type's transparency.
Values for "FILL_ALPHA=" range from 0 (Transparent) to 255 (Opaque). To determine the transparency
value setting simply multiply the percentage by 255 and round off to the nearest integer (e.g. 75%
transparency 0.75 x 255 = 191.25, use 191).
As an example, the default field attributes for the Anchorage Area Type are:
GM_TYPE=Anchorage Area
BORDER_COLOR=RGB(255,0,255)
BORDER_WIDTH=1
BORDER_STYLE=Comb (Right Only)
FILL_COLOR=RGB(255,0,255)
FILL_STYLE=No Fill
To change the type's transparency to 35% the FILL_ALPHA field attribute value should be set equal to 89
(0.35 x 255 = 89.25).
GM_TYPE=Anchorage Area
