-----------------
The TGridPlugin draw a grid of lines at constant and equidistant latitudes and
longitudes. The lines can be labeled at both sides.
Properties
----------
BackgroundColor: TColor
Color of the (semi-transparent) label background
Font: TFont
Font to be used to draw the labels at the grid lines
GridLabels: TMvGridLabels
Parameters for drawing the grid labels:
Distance: Integer
Distance of the labels from the map edges
Position: TMvGridLabelPosition
a set of [glpLeft, glpTop, glpRight, glpBottom] indicating the map sides
at which the labels will appear (
Increment: Double
Distance between the grid lines, in (fractional) degress
The same value Will be applied to both equal-longitude and equal-latitude lines
Note that the distance between equal-latitude lines will grow towards the
poles, due to the projection of the map.
The default value, 0, instructs the plugin to calculate the increment
automatically (determined by MaxDistance and MinDistance parameters).
MaxDistance: Integer
The maximum distance between vertical grid lines in pixels limiting the
automatic calculation of the Increment parameter.
MinDistance: Integer
The minimum distance between vertical grid lines in pixels limiting the
automatic calculation of the Increment parameter.
Opacity: Single
Determines the transparency of the label background
(0 = transparent, 1 = opaque)
Pen: TPen
Determines the color, width and style of the grid lines
