The following table specifies the SYMBOLS parameter:
Examples of the SYMBOLS Parameter
The following example shows how to use SYMBOLS to insert a single symbol,
TestSymbol , at point (2000, 2000) that is 0.001 x 0.001 meters, rotated 30
degrees, and displayed with the label test :
SYMBOLS=TestSymbol,2000,2000,0.001,0.001,30,test
The next example shows how to insert two instances of TestSymbol at points
(2000, 2000) and (2500, 2500), rotated 30 degrees, and labeled test1 and test2 ,
respectively:
SYMBOL=
TestSymbol,2000,2000,0.001,0.001,30,test1,,2500,2500,,,,test2
Default Symbol Layer Styles
You can set the default symbol layer styles in the config.ini file by setting the
SymbolXxx parameters; see Chapter 3, “Configuring Autodesk MapGuide
LiteView,” in the
Autodesk MapGuide LiteView Servlet Administrator’s Guide .
Specification Description
Name The name of an Autodesk MapGuide API symbol. If a symbol
with the specified name is not found, the default symbol (a
black square) is displayed.
X, Y The insertion point, usually the center, defined by the symbol.
By default, the insertion point is specified in the coordinate sys-
tem used by the map MCS, unless it is overridden by the SRS
parameter. If the
X, Y elements fall outside the map range then
the symbol is drawn outside the range. The symbol is clipped if
it falls on the edge of the map.
Width, Height The size of the symbol, expressed in meters.
Rotation The angle of rotation for the symbol, expressed in degrees. The
default value is zero degrees. The angle of rotation is measured
counterclockwise from East and is between -360 to +360,
inclusive.
Label A string of up to 254 characters that labels the symbol’s loca-
tion. You must encode the label if it contains special characters
such as $, & and ?; see “Restricted Characters in the LAYERS
Parameter,” on page 16.
