Constructor & Destructor Documentation

EQRCodeGeometry() [1/4]

eVision::EQRCodeGeometry::EQRCodeGeometry

(

)

Constructs an EQRCodeGeometry::EQRCodeGeometry object.

In case of a Micro QR code (not yet supported), there must be only one finder pattern center. In case of another QR code, there must be three finder pattern centers, entered in the following order: top right, top left, bottom left.

The corners of the EQuadrangle must be entered in the following order : top right, top left, bottom left, bottom right.

EQRCodeGeometry() [2/4]

eVision::EQRCodeGeometry::EQRCodeGeometry

(

const eVision::EQRCodeGeometry &

other

)

Constructs an EQRCodeGeometry::EQRCodeGeometry object.

Parameters

other

Another EQRCodeGeometry::EQRCodeGeometry.

In case of a Micro QR code (not yet supported), there must be only one finder pattern center. In case of another QR code, there must be three finder pattern centers, entered in the following order: top right, top left, bottom left.

The corners of the EQuadrangle must be entered in the following order : top right, top left, bottom left, bottom right.

EQRCodeGeometry() [3/4]

eVision::EQRCodeGeometry::EQRCodeGeometry	(	const eVision::EQuadrangle &	position,
		const std::vector< eVision::EPoint > &	finderPatternCenters )

Constructs an EQRCodeGeometry::EQRCodeGeometry object.

Parameters

position	The position of the QR code represented as an EQuadrangle object.
finderPatternCenters	The vector of Finder Pattern centers.

In case of a Micro QR code (not yet supported), there must be only one finder pattern center. In case of another QR code, there must be three finder pattern centers, entered in the following order: top right, top left, bottom left.

The corners of the EQuadrangle must be entered in the following order : top right, top left, bottom left, bottom right.

Draw() [1/2]

void eVision::EQRCodeGeometry::Draw	(	eVision::EDrawAdapter *	drawAdapter,
		float	zoomX,
		float	zoomY,
		float	panX,
		float	panY )

Draws the QR code geometry.

Parameters

drawAdapter	Draw adapter.
zoomX	Horizontal zooming factor.
zoomY	Vertical zooming factor.
panX	Horizontal panning value expressed in pixels.
panY	Vertical panning value expressed in pixels.

The zoomX, zoomY, panX and panY parameters can be used to scale and/or translate the drawing operations.

Draw() [2/2]

void eVision::EQRCodeGeometry::Draw	(	HDC	hdc,
		float	zoomX,
		float	zoomY,
		float	panX,
		float	panY )

Draws the QR code geometry.

Parameters

hdc	Graphics context.
zoomX	Horizontal zooming factor.
zoomY	Vertical zooming factor.
panX	Horizontal panning value expressed in pixels.
panY	Vertical panning value expressed in pixels.

The zoomX, zoomY, panX and panY parameters can be used to scale and/or translate the drawing operations.

Deprecated

Use the overload taking an EDrawAdapter by using an instance of EWindowsDrawAdapter.

Deprecated in version 23.12. Scheduled to be removed in version 27.6.

DrawWithCurrentPen()

void eVision::EQRCodeGeometry::DrawWithCurrentPen	(	HDC	hDC,
		float	zoomX,
		float	zoomY,
		float	panX,
		float	panY )

Draws the QR code geometry using the pen currently set in the graphical context.

Parameters

hDC	Handle to the device context of the destination window.
zoomX	Horizontal zooming factor.
zoomY	Vertical zooming factor.
panX	Horizontal panning value expressed in pixels.
panY	Vertical panning value expressed in pixels.

The zoomX, zoomY, panX and panY parameters can be used to scale and/or translate the drawing operations.

Deprecated

Use the overload of EQRCodeGeometry::Draw taking an EDrawAdapter by using an instance of EWindowsDrawAdapter.

Deprecated in version 23.12. Scheduled to be removed in version 27.6.

GetFinderPatternCenters()

std::vector< eVision::EPoint > eVision::EQRCodeGeometry::GetFinderPatternCenters

(

)

const

Finder patterns centers.

In case of a Micro QR code, there is only one finder pattern center. In case of another QR code, there are three finder pattern centers, returned in the following order: top right, top left, bottom left.

GetPosition()

eVision::EQuadrangle eVision::EQRCodeGeometry::GetPosition

(

)

const

Position of the QR code returned as an EQuadrangle object.

The EQuadrangle's corners are in the following order: top right, top left, bottom left, bottom right.

operator=()

eVision::EQRCodeGeometry & eVision::EQRCodeGeometry::operator=

(

const eVision::EQRCodeGeometry &

other

)

Assignment operator.

Parameters

other

Another EQRCodeGeometry.

ToRegion()

eVision::ERegion eVision::EQRCodeGeometry::ToRegion

(

)

const

Creates an ERegion from the EQRCodeGeometry.
