<plot_uri>/graphicObject[.<format>]
graphicObject resource is used to get the symbol information.
Supported Methods:
Supported output formats: rjson, json, html, xml.
Implement the HTTP request on the following URI, where supermapiserver is the server name, with rjson being the output format.
http: //supermapiserver: 8090/iserver/services/plot-TY/rest/plot/graphicObject.rjson

| scale2D | Point3D | The scale of the symbol |
| rotate2D | Point3D | The rotation angle of symbol |
| subSymbols | int[] | The collection of sub-symbol. Some line region symbols have sub symbols, new symbols can be got through modifying the code of line region symbols. |
| scaleValues | double[] | The scale value of label |
| surroundLineType | int | Serif type, including sans serif, lining, outer lining, double lining. |
| surroundLineColor | Color | Serif color |
| surroundLineWidth2D | double | Serif width |
| textContent | String | Marker/text content |
| annotationPosition | int | The marker location |
| textStyle2D | TextStyle | The marker style |
| innerCells | GraphicObjectCell[] | The inner primitive information |
| middleMarkExist | boolean | Whether there is a middle note in the symbol |
| algoMaxExitPts | int | The maximum number of line region symbol |
| algoMinEditPts | int | The minimum number of line region symbol |
| middleMarkBounds | Rectangle2D | The middle node range of marker symbol |
Sending Get request to http: //localhost: 8090/iserver/services/plot-TY/rest/plot/graphicObject.rjson?libID=0&code=24, the description for returned rjson format is as follows:

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content. The meta-information includes the media-type, content-encoding, transfer-encoding, content-length, etc.
HEAD request can be used to check if the graphicObject resource exists, or if the geodecoding resource can be accessed by clients. It can also determine if the graphicObject resource supports an output format <format> if performed on a URI with .<format> included.
