Member Function Documentation

DisableDrawArea()

None eVision.EVectorModel.DisableDrawArea

(

self

)

Disables the custom drawing of the eVision.EVectorModel with a specific zoom and pan.

Draw()

None eVision.EVectorModel.Draw	(		self,
		eVision.EDrawAdapter | None	graphicContext )

Draws a graphical representation of the hierarchy.

Parameters

graphicContext

Handle of the device context on which to draw.

EnableDrawArea()

None eVision.EVectorModel.EnableDrawArea	(		self,
		int	drawWindowWidth,
		int	drawWindowHeight )

Enables the drawing of the eVision.EVectorModel with a specific zoom and pan.

Default: false

Parameters

drawWindowWidth	The width of the window that the eVision.EVectorModel is drawn into
drawWindowHeight	The height of the window that the eVision.EVectorModel is drawn into

GetVectorModelExtremas() [1/2]

None eVision.EVectorModel.GetVectorModelExtremas	(		self,
		eVision.EFloatRange	xRange,
		eVision.EFloatRange	yRange )

Retrieves the coordinate extrema of the vector model.

Remarks:

An exception is thrown if the hierarchy is empty

Parameters

xRange	The range along the X axis.
yRange	The range along the Y axis.

GetVectorModelExtremas() [2/2]

None eVision.EVectorModel.GetVectorModelExtremas	(		self,
		eVision.EFloatRange	xRange,
		eVision.EFloatRange	yRange,
		bool	inSensorCoordinates )

Parameters

xRange	The range along the X axis.
yRange	The range along the Y axis.
inSensorCoordinates	Specifies whether the extrema are retrieved in sensor coordinates. Default: false

Load() [1/2]

None eVision.EVectorModel.Load	(		self,
		eVision.ESerializer | None	serializer )

Loads a Shape.The given eVision.ESerializer must have been created for reading.

Parameters

serializer

Pointer to the eVision.ESerializer created for reading.

Load() [2/2]

None eVision.EVectorModel.Load	(		self,
		str	filePath )

Loads a Shape.The given eVision.ESerializer must have been created for reading.

Parameters

filePath

The file path.

LoadDXF() [1/3]

None eVision.EVectorModel.LoadDXF	(		self,
		str	fileName )

Loads an eVision.EVectorModel from an ascii DXF file.

We do not support the whole possibilities offered by the dxf format. We are currently limited to straight polylines, lines, arcs and points. Blocks are ignored at the moment. Angles are assumed to be given in degrees.

Parameters

fileName

The name of the dxf file.

LoadDXF() [2/3]

None eVision.EVectorModel.LoadDXF	(		self,
		str	fileName,
		float	scale )

Loads an eVision.EVectorModel from an ascii DXF file.

We do not support the whole possibilities offered by the dxf format. We are currently limited to straight polylines, lines, arcs and points. Blocks are ignored at the moment. Angles are assumed to be given in degrees.

Parameters

fileName	The name of the dxf file.
scale	The scale of the vector model, defaults to 1.

LoadDXF() [3/3]

None eVision.EVectorModel.LoadDXF	(		self,
		str	fileName,
		float	scale,
		eVision.EPoint	origin )

Loads an eVision.EVectorModel from an ascii DXF file.

We do not support the whole possibilities offered by the dxf format. We are currently limited to straight polylines, lines, arcs and points. Blocks are ignored at the moment. Angles are assumed to be given in degrees.

Parameters

fileName	The name of the dxf file.
scale	The scale of the vector model, defaults to 1.
origin	The origin of the EVectorModel in the dxf's coordinates. If not specified, we try to parse the origin from the UCSORG field in the dxf headers. Otherwise, origin is (0, 0).

Save() [1/2]

None eVision.EVectorModel.Save	(		self,
		eVision.ESerializer | None	serializer )

Saves a Shape.The given eVision.ESerializer must have been created for writing.

Parameters

serializer

Pointer to the eVision.ESerializer created for writing.

Save() [2/2]

None eVision.EVectorModel.Save	(		self,
		str	filePath )

Saves a Shape.The given eVision.ESerializer must have been created for writing.

Parameters

filePath

The file path.
