#include <qgsimageoperation.h>

Public Attributes
QgsColorRamp *	ramp = nullptr
	Color ramp to use for shading the distance transform.

bool	shadeExterior = true
	Set to `true` to perform the distance transform on transparent pixels in the source image, set to `false` to perform the distance transform on opaque pixels.

double	spread = 10.0
	Maximum distance (in pixels) for the distance transform shading to spread.

bool	useMaxDistance = true
	Set to `true` to automatically calculate the maximum distance in the transform to use as the spread value.
