Class VectorInfo

java.lang.Object

com.mousebird.maply.BaseInfo

com.mousebird.maply.VectorInfo

public class VectorInfo
extends BaseInfo

The Vector Info class holds visual information related to groups of vectors. For efficiency's sake we put visual info in this class, rather than on attributes in the vectors themselves. There may be attributes that can override these, however.

Field Detail

VectorPriorityDefault

public static int VectorPriorityDefault

Default draw priority for vector features.

Constructor Detail

VectorInfo

public VectorInfo()

Construct the vector info empty with default values. At the very least a vector will be white and visible all the time.

Method Detail

finalize

public void finalize()

Overrides:

finalize in class java.lang.Object

setFilled

public void setFilled(boolean filled)

Set whether or not areal features are tesselated and draw as filled. Default is fault.

setSampleEpsilon

public void setSampleEpsilon(double eps)

Vectors can be subdivided to follow a globe. If set, this is the offset from the globe that will trigger a subdivision.

setTexture

public void setTexture(MaplyTexture tex)

If set and filled is set, we will apply the given texture across any areal features. How the texture is applied can be controlled by the textScale, textureProjection, and vecCenter.

setTexScale

public void setTexScale(double u,
                        double v)

These control the scale of the texture application. We'll multiply by these numbers before generating texture coordinates from the vertices.

setSubdivEps

public void setSubdivEps(double eps)

If set, we'll subdivide areal features on top of the globe using a grid to figure out the optimal subdivision. This is the vertical distance from the globe to use as a trigger for more subdivision.

setTextureProjection

public void setTextureProjection(VectorInfo.TextureProjection texProjection)

setColor

public void setColor(int color)

Set the color used by the geometry.

Parameters:

color - Color in Android format, including alpha.

setColor

public void setColor(float r,
                     float g,
                     float b,
                     float a)

Set the color used by the geometry. Color values range from 0 to 1.0. You must specify all four values. Alpha controls transparency.

Parameters:

r - Red component.

g - Green component.

b - Blue component.

a - Alpha component.

setLineWidth

public void setLineWidth(float lineWidth)

This is the line width for vector features. By default this is 1.0.

setUseCenter

public void setUseCenter()

If set, we'll calculate a center for the vector geometry and use that in building the visual geometry. This is set on by default when we pass in a center as well.

setVecCenter

public void setVecCenter(Point2d center)

These control the center of a texture application. If not set we'll use the areal's centroid. If set, we'll use these instead. They should be in local coordinates (probably geographic radians).

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
