◆ dt_heal_domain_t

typedef enum dt_heal_domain_t dt_heal_domain_t

The domain the source-to-destination difference is interpolated in.

LINEAR adds a harmonic correction to the source pixels as they are, so a source brighter than the destination keeps its absolute noise and texture amplitude on a darker base: once encoded for display, that noise is stronger than the destination's own.

SQRT interpolates the difference of square roots, the variance-stabilising transform of shot noise, so the pasted noise takes the amplitude it would have had at the destination level. Only the three colour channels are transformed; the fourth stays linear.

◆ dt_heal_solver_t

typedef struct dt_heal_solver_t dt_heal_solver_t

How the fill is solved; both settings come from the calling module.

Function Documentation

◆ dt_heal()

void dt_heal	(	const float *const	src_buffer,
		float *	dest_buffer,
		const float *const	mask_buffer,
		const int	width,
		const int	height,
		const int	ch,
		const dt_heal_solver_t	solver
	)

Heal dest_buffer using src_buffer as a reference and mask_buffer to define the area to be healed. The 3 buffers must have the same size, but mask_buffer is 1 channel and is tested for != 0.f.
