Sets a polyline gradient.
Synopsis
void setPolyLineGradient(string strLayer, string strField, string strValue,
string strPattern, double dPercent, int iLength);
Parameters
| Parameter | Description |
|---|---|
| strLayer | The name of the layer whose polyline will be set to gradient. |
| strField | The name of the layer field. |
| strValue | The name of the polyline. |
| strPattern | The pattern that should be set. At the moment the pattern "water" is supported. |
| dPercent | The percent for the pattern setting. |
| iLength | The length for the pattern. |
Description
Sets a polyline gradient.
Example
Adds a polyline to the GIS viewer and sets the polyline gradient.
main()
{
GisViewer_ewo1.addEmptyLayer("EWO");
GisViewer_ewo1.setLayerFillColor("EWO","red");
GisViewer_ewo1.setLayerLineColor("EWO","red");
int iPoly;
iPoly = GisViewer_ewo1.addPolylineToLayer( "EWO", "Helsinki", 4 );
//adds a polyline
GisViewer_ewo1.addPointToPolyline( iPoly, 0, 25, 60 );
GisViewer_ewo1.addPointToPolyline( iPoly, 1, 26, 61 );
GisViewer_ewo1.addPointToPolyline( iPoly, 2, 24, 62 );
GisViewer_ewo1.addPointToPolyline( iPoly, 3, 25, 60 );
GisViewer_ewo1.setPolyLineGradient( "EWO", "NAME", "Helsinki", "water",2, 1 ); //sets the polyline gradient
