Class Mollweide
- All Implemented Interfaces:
- Serializable,- Parameterized,- LenientComparable,- MathTransform,- MathTransform2D
Mollweide projection.
 See the following references for an overview:
 
- Since:
- 1.0
- See Also:
- TODO:
- This projection is not surjective. Consequently,CRS.suggestCommonTarget(…)may not work correctly if a CRS uses this projection. See SIS-427.

Constructor Details- 
MollweideCreates a Mollweide projection from the given parameters. Themethodargument can be the description of one of the following:- "Mollweide", also known as "Homalographic" or "Homolographic".
 - Parameters:

Method Details- 
transformpublic Matrix transform(double[] srcPts, int srcOff, double[] dstPts, int dstOff, boolean derivate) throws ProjectionException Projects the specified (Λ,φ) coordinates and stores the (x,y) result indstPts. The units of measurement are implementation-specific (see super-class javadoc). The results must be multiplied by the denormalization matrix before to get linear distances.- Specified by:
- transformin class- NormalizedProjection
- Parameters:
- srcPts- the array containing the source point coordinates, as (longitude, latitude) angles in radians.
- srcOff- the offset of the single coordinate tuple to be converted in the source array.
- dstPts- the array into which the converted coordinates is returned (may be the same than- srcPts). Coordinates will be expressed in a dimensionless unit, as a linear distance on a unit sphere or ellipse.
- dstOff- the offset of the location of the converted coordinates that is stored in the destination array.
- derivate-- truefor computing the derivative, or- falseif not needed.
- Returns:
- the matrix of the projection derivative at the given source position,
         or nullif thederivateargument isfalse.
- Throws:
- ProjectionException- if the coordinates cannot be converted.

inverseTransformprotected void inverseTransform(double[] srcPts, int srcOff, double[] dstPts, int dstOff) Converts the specified (x,y) coordinates and stores the result indstPts(angles in radians).- Specified by:
- inverseTransformin class- NormalizedProjection
- Parameters:
- srcPts- the array containing the source point coordinates, as linear distance on a unit sphere or ellipse.
- srcOff- the offset of the point to be converted in the source array.
- dstPts- the array into which the converted point coordinates is returned (may be the same than- srcPts). Coordinates will be (longitude, latitude) angles in radians.
- dstOff- the offset of the location of the converted point that is stored in the destination array.
