Constructor Detail

MilStd2525ModifierRetriever

public MilStd2525ModifierRetriever(String retrieverPath)

Create a new retriever that will retrieve icons from the specified location.

Parameters:

retrieverPath - File path or URL to the symbol directory, for example "http://myserver.com/milstd2525/".

Method Detail

chooseBestFittingWidth

protected Integer chooseBestFittingWidth(AVList params)

composePath

protected String composePath(String symbolModifierCode,
                             AVList params)

createIcon

public BufferedImage createIcon(String symbolId,
                                AVList params)

Create an icon for a symbol modifier.

Parameters:

symbolId - Identifier for the modifier. This identifier is fields 11 and 12 of a MIL-STD-2525C SIDC (see MIL-STD-2525C Table A-I, pg. 51).

params - Parameters that affect icon retrieval. This retriever accepts only one parameter: AVKey.COLOR, which determines the color of the modifier (default is black).

Returns:

BufferedImage containing the requested modifier, or null if the modifier cannot be retrieved.

getColorFromParams

protected Color getColorFromParams(AVList params)

Retrieves the value of the AVKey.COLOR parameter.

Parameters:

params - Parameter list.

Returns:

The value of the AVKey.COLOR parameter, if such a parameter exists and is of type java.awt.Color. Returns null if the parameter list is null, if there is no value for key AVKey.COLOR, or if the value is not a Color.

isVariableWidth

protected boolean isVariableWidth(AVList params)

mustApplyColor

protected boolean mustApplyColor(String symbolId)

Indicates whether or not color must be applied to the modifier. Color is applied to all modifiers except for alternate Operational Condition modifiers, which have their own color.

Parameters:

symbolId - Modifier id.

Returns:

True if color must be applied to the modifier.
