ImageProfileAlongPath

Header:	FIL.h
Namespace:	fil

Creates a series of segments across the input path, measures the average pixel intensity on each of the segments, and creates the final profile from that values.

Syntax

void fil::ImageProfileAlongPath
(
	ImageProfileAlongPathState& ioState,
	const fil::Image& inImage,
	const fil::Path& inScanPath,
	ftl::Optional<const fil::CoordinateSystem2D&> inScanPathAlignment,
	int inScanWidth,
	fil::InterpolationMethod::Type inInterpolationMethod,
	float inSmoothingStdDev,
	fil::Profile& outProfile,
	fil::Path& outPath,
	ftl::Optional<fil::Path&> outAlignedScanPath = ftl::NIL,
	ftl::Array<fil::Path>& diagSamplingPoints
)

Parameters

Name	Type	Range	Default	Description
ioState	ImageProfileAlongPathState&			Object used to maintain state of the function.
inImage	const Image&			Input image
inScanPath	const Path&			Path along which the profile is extracted
inScanPathAlignment	Optional<const CoordinateSystem2D&>		NIL	Adjusts the scan path to the position of the inspected object
inScanWidth	int	1 -	5	Width of the scan area
inInterpolationMethod	InterpolationMethod::Type		Bilinear	Interpolation method used to compute pixel brightness in locations of not-integer coordinates
inSmoothingStdDev	float	0.0 -	0.6f	Standard deviation of the gaussian smoothing applied to the extracted profile
outProfile	Profile&			The resulting profile of the pixel brightness
outPath	Path&			The path consisting of the points from which the resulting profile is extracted
outAlignedScanPath	Optional<Path&>		NIL	Input scan path after transformation (in the image coordinates)
diagSamplingPoints	Array<Path>&			Array of paths each one containing the sampling points that contributed to a single value of the extracted profile

Optional Outputs

The computation of following outputs can be switched off by passing value ftl::NIL to these parameters: outAlignedScanPath.

Examples
