Detailed Description

Fix out-of-gamut colors in images by remapping them back into the RGB gamut.

This class provides multiple methods for handling colors that fall outside
the standard RGB color gamut, including inpainting, mapping functions,
and diffusion-based healing.

◆ call()

RGBImage lsst.pipe.tasks.prettyPictureMaker._functors._gamut_fixer.GamutFixer.__call__	(		self,
		LABImage	Lab,
		tuple[float, float]	xyz_whitepoint )

Remap colors that fall outside an RGB color gamut back into it.

When gamutMethod is 'heal', regions larger than the configured max_size
are skipped.

Parameters
----------
Lab : `LABImage`
    A NxMx3 array in the Lab colorspace containing the image data.
xyz_whitepoint : `tuple` of `float`, `float`
    Sets the white point of the xyz colorspace in xy coordinates.

Returns
-------
result : `RGBImage`
    The image with out-of-gamut colors remapped to RGB colorspace.

Raises
------
ValueError
    Raise if the gamut method is not one of the supported methods.
