"setLayerPointSymbol"

Sets a displaying symbol for a point on a specific layer

Synopsis

void setLayerPointSymbol(string strLayer, double dSize, int iMinSize, int iMaxSize, int iSymbol);

Parameters

Parameter Description
strLayer The layer the symbol will be added to.
dSize Size of the object specified in the coordinate system of your map. Example: when your map is a longitude.lattitude coordinate system, then a value of 1.0 would mean 1 degree ( which would be roughly a shape 40 kilometers wide ). When you use a map that uses meters, this value would be the size of the symbol in meters.
iMinSize The minimum size of the symbol.
iMaxSize The maximum size of the symbol.
iSymbol

The symbol:

0 = POINTSHAPE_RECTANGLE,

1 = POINTSHAPE_CIRCLE,

2 = POINTSHAPE_TRIANGLE_UP,

3 = POINTSHAPE_TRIANGLE_LEFT,

4 = POINTSHAPE_TRIANGLE_RIGHT,

5 = POINTSHAPE_TRIANGLE_DOWN,

6 = POINTSHAPE_RECTANGLE_DOUBLE_EDGE,

7 = POINTSHAPE_TRIANGLE_UP_DOUBLE_EDGE,

8 = POINTSHAPE_CIRCLE_DOUBLE_EDGE,

9 = POINTSHAPE_HALF_CIRCLE,

10 = POINTSHAPE_VALVE,

11 = POINTSHAPE_PUMP,

12 = POINTSHAPE_CIRCLE_HALF_CIRCLE,

13 = POINTSHAPE_CIRCLE_HALF_CIRCLE_DOUBLE_EDGE,

14 = POINTSHAPE_MOBILE_GENERATOR

Description

Sets a displaying symbol for a point on a specific layer. The size, the maximum and minimum size as well as the type of symbol can be specified.

Example

The code below will set the layer point symbol to circle.

main()
{
  GisViewer_ewo1.setLayerPointSymbol("COUNTRY", 2, 2, 5,2);
}
