Types

type Affine2DParameters

type Affine2DParameters struct {
	A, B, C float64 // Transformation for X: x' = A*x + B*y + C
	D, E, F float64 // Transformation for Y: y' = D*x + E*y + F
}

Affine2DParameters represents the parameters of a 2D affine transformation.

type SIP2DForwardParameters

type SIP2DForwardParameters struct {
	AOrder int
	APower map[string]float64
	BOrder int
	BPower map[string]float64
}

The forward parameters are polynomial coefficients used to map from pixel coordinates to world coordinates.

type SIP2DInverseParameters

type SIP2DInverseParameters struct {
	APOrder int
	APPower map[string]float64
	BPOrder int
	BPPower map[string]float64
}

The inverse paramaters are polynomial coefficients used to map from world coordinates to pixel coordinates.
