_shared_simple_hue_probe()

static void _shared_simple_hue_probe ( const float  hue, float  module_color[3]  )

static

Build a stable hue cue in the fixed chroma basis for hue-like sliders.

Some simple-mode parameters become ineffective for degenerate mixer states, for example when the chroma stretches collapse or when the achromatic coupling amount is zero. In those cases, effect-based slider painting can legitimately converge to grey and the hue ramp disappears. This helper keeps a readable hue cue in reserve by projecting a constant-chroma vector from the fixed simple-mode basis into module RGB coordinates.

Parameters

[in]	hue	Angular direction in the chroma plane.
[out]	module_color	Probe color in module RGB coordinates.

static gboolean _white_preserving_point_from_polar ( const float  white_normalized[3], const float  reference_primaries[3][2], const int  reference_index, const float  rotation, const float  saturation, float  point_normalized[3]  )

static

Place one white-preserving primary from its rotation and saturation.

Unlike the generalized primaries model, the radius is measured against the REFERENCE primary itself rather than against the gamut footprint edge, so the control reads as a saturation : 0 keeps the basis primary, -1 collapses it onto the white, +1 doubles its distance to it.

Parameters

[in]	white_normalized	Basis white, normalized in the affine plane.
[in]	reference_primaries	Affine coordinates of the three basis primaries.
[in]	reference_index	Which primary is being placed.
[in]	rotation	Rotation around the white, in radians.
[in]	saturation	Radial scaling of the distance to the white, by 1 + saturation.
[out]	point_normalized	Resulting chromaticity, normalized in the affine plane.

Returns

FALSE when the reference primary is degenerate.

static

Read back the rotation and saturation of one white-preserving primary.

Parameters

[in]	white_normalized	Basis white, normalized in the affine plane.
[in]	reference_primaries	Affine coordinates of the three basis primaries.
[in]	reference_index	Which primary is being read.
[in]	point_normalized	Chromaticity of the mixer column, normalized in the affine plane.
[out]	rotation	Rotation around the white, in radians.
[out]	saturation	Radial scaling of the distance to the white, minus one.

Returns

FALSE when the reference primary is degenerate.

float dt_iop_channelmixer_shared_roundtrip_error_relative	(	const float	M[3][3],
		const float	roundtrip[3][3]
	)

Roundtrip error, measured against the magnitude of the matrix itself.

A reduced mixer model is a reparametrization, so the question its gate asks is whether the rebuilt matrix is the SAME matrix, which is a relative question. Comparing an absolute coefficient difference against a fixed tolerance silently demands more and more precision as the coefficients grow, and the white-preserving model can legitimately produce large ones : two primaries rotated onto the same ray make the chromaticity basis near-singular, which inflates the column scales that the white constraint solves for. The denominator is floored at 1 so ordinary, near-identity matrices keep the plain absolute behaviour.

Parameters

[in]	M	Original mixer matrix.
[in]	roundtrip	Matrix rebuilt from the parameters read back from M.

Returns

Largest coefficient error, relative to the largest coefficient magnitude.

	)

Read a white-preserving primaries state back from a mixer matrix.

Only the column DIRECTIONS are read here, so this succeeds for any matrix whose columns have a non-zero affine sum, white-preserving or not. Callers must gate on the roundtrip error against dt_iop_channelmixer_shared_white_preserving_to_matrix() to know whether the matrix actually sits on the white-preserving submanifold : a matrix that moves the white reconstructs to a different one, exactly like the other reduced mixer models.

Parameters

[in]	basis	Affine basis the mixer operates in, from the module's adaptation.
[in]	M	Mixer matrix.
[out]	white_preserving	Per-primary rotations and saturations.

Returns

FALSE when a column has a null affine sum or the basis is degenerate.

		float	M[3][3]
	)

Build the mixer matrix of a white-preserving primaries state.

The three rotated and rescaled chromaticities give the DIRECTION of each mixer column. Their magnitudes are then solved from the single constraint that the basis white maps to itself : with t = P^-1 . w (P holding the chromaticities in columns), column c of the matrix is t_c / w_c times chromaticity c, and M . w == w holds by construction.

Parameters

[in]	basis	Affine basis the mixer operates in, from the module's adaptation.
[in]	white_preserving	Per-primary rotations and saturations.
[out]	M	Resulting mixer matrix.

Returns

FALSE when the displaced primaries are degenerate or the basis white has a null channel.
