IconRetriever
public class MilStd2525PointGraphicRetriever extends AbstractIconRetriever
Retriever to fetch icons for MIL-STD-2525C point graphics. The retriever can fetch images from either local or remote locations. See Offline Use for information on how to set the icon retrieval location.The retriever base URL must identify a location on a local or remote file system (including zip and jar files) that holds the icon files in an expected directory structure. Each icon URL is constructed from three parts: [base]/icons/[scheme]/[sidc].png. Parts of the SIDC that do not identify a type of graphic (such as echelon, status, standard identity, order of battle, etc.) are replaced with hyphens. For example, the Underwater Datum graphic (2.X.2.1.1.1.1.1) will be retrieved from this URL: [base]/icons/tacgrp/g-g-gpuud------.png
An application should only use this class directly if it needs to access point graphics independent of the
TacticalGraphic
system (for example, to populate a UI independent of the globe).

MilStd2525PointGraphicRetriever
public MilStd2525PointGraphicRetriever(java.lang.String retrieverPath)
Create a new retriever that will retrieve icons from the specified location. The retrieval path may be a file URL to a directory on the local file system (for example, file:///symbols/mil-std-2525). A URL to a network resource (http://myserver.com/milstd2525/), or a URL to a JAR or ZIP file (jar:file:milstd2525-symbols.zip!).- Parameters:
retrieverPath
- File path or URL to the symbol directory, for example "http://myserver.com/milstd2525/".

createIcon
public java.awt.image.BufferedImage createIcon(java.lang.String sidc, AVList params)
Create an icon for a MIL-STD-2525C point graphic. Point graphics are defined in Appendixes B (Tactical Graphics), C (Meteorological and Oceanographic), and G (Emergency Management).- Parameters:
sidc
- SIDC identifier for the symbol.params
- Parameters that affect icon retrieval. This retriever accepts only one parameter: AVKey.COLOR, which determines the color of the image. By default the color will be determined from the standard identity.- Returns:
- An BufferedImage containing the icon for the requested graphic, or null if the icon cannot be retrieved.
-
composeFilledImage
protected java.awt.image.BufferedImage composeFilledImage(java.awt.image.BufferedImage srcImg, SymbolCode symbolCode)
Create an image by drawing over a fill image.- Parameters:
srcImg
- Image to draw over fill.symbolCode
- Symbol code that identifies the graphic.- Returns:
- A new image with the
srcImg
drawn over the appropriate fill.
-
mustDrawFill
protected boolean mustDrawFill(SymbolCode code)
Indicates whether or not a fill must be drawn for a graphic.- Parameters:
code
- Symbol code of a point graphic.- Returns:
- True if the graphic has a fill image. False if not. Only three graphics in MIL-STD-2525C Appendix B use a fill pattern: Nuclear Detonation Ground Zero (2.X.3.4.2), Biological Release Event (2.X.3.4.7.1), and Chemical Release Event (2.X.3.4.7.2).
-
getColorFromParams
protected java.awt.Color getColorFromParams(AVList params)
Retrieves the value of the AVKey.COLOR parameter.- Parameters:
