Constructor & Destructor Documentation

◆ FingerImage() [1/2]

PFTIII::FingerImage::FingerImage ( )

Default constructor.

Definition at line 13 of file libpftiii.cpp.

◆ FingerImage() [2/2]

PFTIII::FingerImage::FingerImage	(	const uint16_t	width,
		const uint16_t	height,
		const uint16_t	ppi,
		const std::vector< std::byte > &	pixels,
		const Impression	imp = `Impression::Unknown`,
		const FrictionRidgeCaptureTechnology	frct = `FrictionRidgeCaptureTechnology::Unknown`,
		const FrictionRidgeGeneralizedPosition	frgp = `FrictionRidgeGeneralizedPosition::Unknown`
	)

FingerImage constructor.

Parameters

width	Width of the image.
height	Height of the image.
ppi	Resolution of the image in pixels per inch.
pixels	`width` * `height` bytes of image data, with `pixels.front()` representing the top-left pixel, and `pixels.back()` representing the bottom-right pixel. It is raw, single- channel image data, canonically coded as defined in ISO/IEC 19794-4:2005, section 6.2.
imp	Impression type of the finger.
frct	Capture technology that created this image.
frgp	Friction ridge generalized position of the finger.

Member Data Documentation

◆ width

uint16_t PFTIII::FingerImage::width {}

Width of the image.

Definition at line 129 of file pftiii.h.

◆ height

uint16_t PFTIII::FingerImage::height {}

Height of the image.

Definition at line 131 of file pftiii.h.

◆ ppi

uint16_t PFTIII::FingerImage::ppi {}

Resolution of the image in pixels per inch.

Definition at line 133 of file pftiii.h.

◆ pixels

std::vector<std::byte> PFTIII::FingerImage::pixels {}

Raw pixel data of image.

width * height bytes of image data, with pixels.front() representing the top-left pixel, and pixels.back() representing the bottom-right pixel. It is raw, single- channel image data, canonically coded as defined in ISO/IEC 19794-4:2005, section 6.2.

Note: To pass pixels to a C-style array, invoke pixel's data() method (pixels.data()).

Definition at line 149 of file pftiii.h.

◆ imp

Impression PFTIII::FingerImage::imp {Impression::Unknown}

Impression type of the depicted finger.

Definition at line 151 of file pftiii.h.

◆ frct

FrictionRidgeCaptureTechnology PFTIII::FingerImage::frct

Initial value:

{

FrictionRidgeCaptureTechnology::Unknown}

Capture technology that created this image.

Definition at line 153 of file pftiii.h.

◆ frgp

FrictionRidgeGeneralizedPosition PFTIII::FingerImage::frgp

Initial value:

{

FrictionRidgeGeneralizedPosition::Unknown}

Position of the depicted finger.
