Constructor & Destructor Documentation

__init__() [1/3]

None eVision.EQRCodeGeometry.__init__

(

self

)

Constructs an eVision.EQRCodeGeometry.__init__ object.

Remarks:

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 eVision.EQuadrangle must be entered in the following order : top right, top left, bottom left, bottom right.

__init__() [2/3]

None eVision.EQRCodeGeometry.__init__	(		self,
		eVision.EQRCodeGeometry	other )

Constructs an eVision.EQRCodeGeometry.__init__ object.

Remarks:

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 eVision.EQuadrangle must be entered in the following order : top right, top left, bottom left, bottom right.

Parameters

other

Another eVision.EQRCodeGeometry.__init__.

__init__() [3/3]

None eVision.EQRCodeGeometry.__init__	(		self,
		eVision.EQuadrangle	position,
		list[eVision._eVision.EPoint]	finderPatternCenters )

Constructs an eVision.EQRCodeGeometry.__init__ object.

Remarks:

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 eVision.EQuadrangle must be entered in the following order : top right, top left, bottom left, bottom right.

Parameters

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

Member Function Documentation

Draw()

None eVision.EQRCodeGeometry.Draw	(		self,
		eVision.EDrawAdapter | None	drawAdapter,
		float	zoomX,
		float	zoomY,
		float	panX,
		float	panY )

Draws the QR code geometry.

Remarks:

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

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.

FinderPatternCenters()

list[eVision._eVision.EPoint] eVision.EQRCodeGeometry.FinderPatternCenters

(

self

)

Finder patterns centers.

Remarks:

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.

Position()

eVision.EQuadrangle eVision.EQRCodeGeometry.Position

(

self

)

Position of the QR code returned as an eVision.EQuadrangle object.

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

ToRegion()

eVision.ERegion eVision.EQRCodeGeometry.ToRegion

(

self

)

Creates an eVision.ERegion from the eVision.EQRCodeGeometry.
