Method Detail

setGeoPointNumber

public void setGeoPointNumber(int pGeoPointNumber)

Ignore most of the time. Only useful if you display a closed polyline with gradients: * when displaying a segment with a gradient, you compute the gradient from the current segment's color to the next segment's color * in the closing segment case, we compute normally the color of the last segment, but we also need to know the color of the next segment, which is the very first segment That's why we need to know the number of segments. Without that information, we would just give the next color of the cycle.

Parameters:

pGeoPointNumber - Number of GeoPoints of the polyline

public int getColorForIndex(int pSegmentIndex)
