frame Reference frame in which the EQuadrangle is defined.

◆ SetPoint()

void eVision.EQuadrangle.SetPoint	(	uint	index,
		eVision.EPoint	location )

Sets the coordinates of a given corner of the quadrangle.

Parameters

index	The index of the corner of interest (must lie in the range between 0 and 3, inclusive).
location	The coordinate.

Member Data Documentation

◆ Corner0

eVision.EPoint eVision.EQuadrangle.Corner0

Corner 0 of the quadrangle.

◆ Corner1

eVision.EPoint eVision.EQuadrangle.Corner1

Corner 1 of the quadrangle.

◆ Corner2

eVision.EPoint eVision.EQuadrangle.Corner2

Property Documentation

◆ Area

float eVision.EQuadrangle.Area

get

Returns the area of the quadrangle.

◆ Corners

eVision.EPoint [] eVision.EQuadrangle.Corners

get

The corners of the EQuadrangle.

If the EQuadrangle belongs to an EQRCodeGeometry object, the corners are returned in the following order: top right, top left, bottom left, bottom right. If the EQuadrangle belongs to an EBarCode or EMatrixCode object, the corners are returned in the following order: top left, top right, bottom right, bottom left. Here, top left and so on means the top left of the code, not the top left of the image.

◆ GravityCenter

eVision.EPoint eVision.EQuadrangle.GravityCenter

get

Returns the gravity center of the quadrangle.

◆ Perimeter

float eVision.EQuadrangle.Perimeter

get

Returns the perimeter of the quadrangle.

◆ UpperLeftCorner

eVision.EPoint eVision.EQuadrangle.UpperLeftCorner

get

Returns the coordinates of the upper left corner of the quadrangle (the position with the minimum Y and then minimum X).
