The class diagram for map layers for graphic objects is shown in Layers for Graphic Objects UML Diagram.
Layers for Graphic Objects UML Diagram
Most map layers are used to manage graphic
objects created from map features imported from various map data
files. The styling options differ according to the content of each
file and the map features imported by the different readers. For
example, you do not style a polygon the same way you do an altitude
raster image.
The IlvGeneralPathStyle class
The IlvGeneralPathStyle class is used for IlvMapGeneralPath stylable graphic objects.
Generally, most vectorial map renderers provide a
setUsingGeneralPath
method to allow a choice between using general paths, which give
a better aspect and capabilities, or regular polygons, which
provide better performance.
General Path Styling Properties
Property
name |
Content |
|---|---|
FILL_PAINT |
Paint
object used to fill the shape.
|
STROKE_PAINT |
Paint
object used when stroking the path.
|
FILL_ON |
Boolean
indicating whether the inside of the object is filled.
|
STROKE_ON |
Boolean
indicating whether the shape of the object is stroked.
|
PAINT_ABSOLUTE |
Boolean
indicating whether the fill paint is adapted to the bounding
rectangle of the object.
|
STROKE_WIDTH |
Stroke
width. |
PAINT_ZOOMED |
Boolean
indicating whether the paint is zoomed according to the shape
when the object is zoomed.
|
END_CAP |
Type of decoration applied to the ends of unclosed subpaths
(see
java.awt.BasicStroke
).
|
LINE_JOIN |
Type of decoration applied at the intersection of two path
segments (see
java.awt.BasicStroke
).
|
LINE_STYLE |
Float table indicating how to make a dash pattern by
alternating between opaque and transparent sections (see
java.awt.BasicStroke
).
|
STROKE |
Object
used for stroking the path. This attribute is dependant on
all stroke attributes and is recomputed when one of them
changes.This attribute is not visible in the Map Layer Tree
Panel. |
The IlvPolylineStyle class
The IlvPolylineStyle class is used for IlvMapPolyline stylable objects (polygons
or polylines without fill).
Polyline Styling Properties
Property
name |
Content |
|---|---|
FOREGROUND |
Color
object used when drawing the polygon borders.
|
LINE_WIDTH |
Polygon
borders line width. |
END_CAP |
Type of decoration applied to the ends of unclosed subpaths
(see
java.awt.BasicStroke
).
|
LINE_JOIN |
Type of decoration applied at the intersection of two path
segments (see
java.awt.BasicStroke
).
|
LINE_STYLE |
Float table indicating how to make a dash pattern by
alternating between opaque and transparent sections (see
java.awt.BasicStroke
).
|
DECORATION |
Additional
IlvPathDecoration
object used for stroking the polygon.
|
DECORATION_ONLY |
Boolean
indicating whether only the decoration is displayed.
|
DECORATION_PAINT |
Paint
color of the decoration. By default (when this attribute is
null), the decoration is colored using the FOREGROUND
attribute. |
The IlvGraphicPathStyle class
The IlvGraphicPathStyle class is a subclass of
IlvPolylineStyle and so provides all the
attributes in The IlvPolylineStyle class. It provides the
style for
IlvMapGraphicPath
objects (filled polygon areas), by adding:
Graphic Path Styling Properties
Property
name |
Content |
|---|---|
PAINT |
Paint
object used to fill the polygon area.
|
DO_FILL |
Boolean
indicating whether the inside of the polygon is filled.
|
DO_STROKE |
Boolean
indicating whether the borders of the polygon are stroked.
|
The IlvPointStyle class
The IlvPointStyle class controls the style of
map point ( IlvMapPoint) objects. It provides the
following attributes:
Point Styling Properties
Property
name |
Content |
|---|---|
FOREGROUND |
Color
object used for displaying the point.
|
MARKER_SIZE |
The
size of the marker. |
MARKER_TYPE |
The
type of marker to use. |
The IlvMapTextStyle class
The IlvMapTextStyle class controls the style of
map stylable label objects ( IlvMapText). It provides the following
attributes:
Map Text Styling Properties
Property
name |
Content |
|---|---|
ANTIALIASING |
Boolean
indicating whether text should be specifically antialiased
(even if the view setting itself is different).
|
ATTACHMENT |
The
label attachment. |
FILL_PAINT |
Paint
object used to fill the characters of the text.
|
FONT |
The label
Font
.
|
FRAME_PAINT |
Paint
object used to draw the frame of the label.
|
INNER_MARGIN |
Spacing
between the frame of the label and the text. |
INTERLINE |
Spacing
between two lines of text. |
MAXIMUM_HEIGHT |
The
maximum height of the label. |
MINIMUM_HEIGHT |
The
minimum height of the label. |
STROKE_PAINT |
Paint
object used to draw the shape of the text character.
|
BACKGROUND_PAINT |
Paint
object used to fill the frame of the label.
|
ALIGNMENT |
Alignment
of the multi-line text. |
The IlvRasterStyle class
The IlvRasterStyle class is used with IlvRasterIcon graphic objects, and provides
attributes to control the appearance of the image:
Raster Styling Properties
Property
name |
Content |
|---|---|
BRIGHTNESS |
A
Double
percentage applied to the color model to make the entire
image brighter or darker. 0% gives a black image.
|
CONTRAST |
A
Double
percentage applied to the color model to increase the color
difference. 0% gives a completely grey image.
|
SATURATION |
A
Double
percentage applied to the color model of the image to change
the color saturation. 0% gives a completely grey image.
|
COLOR_MODEL |
The
ColorModel
object used to transform the pixel values of the image into
RGBA colors.
