Uses of Matrix in starfish.core.boundaries

Methods in starfish.core.boundaries with parameters of type Matrix

Modifier and Type	Method and Description
void	BoundaryModule.NewBoundary(org.w3c.dom.Element element, Matrix G, boolean flip_normals_global) ads a new boundary
void	Spline.setPath(java.lang.String path, Matrix T, boolean flip_normals) Sets the spline using a SVG-like path syntax: M x y : moves the current position to x y L x y : creates a linear segment from current position to (x,y) C k1x k1y k2x k2y x y : creates a cubic segment from current position to (x,y) using knots k1 and k2 S x y : creates a smooth segment from current position to (x,y) Z : adds discontinuity into the spline Unlike SVG, the cubic path is specified only by the final position.
