Member Function Documentation

Draw() [1/30]

None eVision.EROIBW32f.Draw	(		self,
		ctypes.c_void_p	graphicContext )

Draws an ROI/image in a device context.

Remarks:

An ROI/image can be drawn (its pixels rendered) using a device context.

The horizontal and vertical zooming factors can be different and must be contained in the 1/16..16 range. (MFC users can use the CDC::GetSafeHdc() method to obtain a suitable device context handle from a CDC instance.)

Parameters

graphicContext

Handle to the device context of the destination window.

Reimplemented from eVision.EBaseROI.

Draw() [2/30]

None eVision.EROIBW32f.Draw	(		self,
		ctypes.c_void_p	graphicContext,
		eVision.EBW8Vector | None	bw8Vector )

Draws an ROI/image in a device context.

Remarks:

An ROI/image can be drawn (its pixels rendered) using a device context.

The horizontal and vertical zooming factors can be different and must be contained in the 1/16..16 range. (MFC users can use the CDC::GetSafeHdc() method to obtain a suitable device context handle from a CDC instance.)

Parameters

graphicContext	Handle to the device context of the destination window.
bw8Vector	When supplied, this parameter allows using a LUT that maps from BW8 to BW8 when drawing.

Reimplemented from eVision.EBaseROI.

None eVision.EROIBW32f.DrawFrame	(		self,
		ctypes.c_void_p	graphicContext,
		bool	handles,
		float	zoomX,
		float	zoomY )

Draws a rectangular frame around an image or ROI.

Remarks:

A frame can be drawn (using a device context) around an image or ROI, possibly with 9 sizing handles. A suitable default pen is used (see eVision.EROIBW32f.DrawFrameWithCurrentPen if you wish to use the pen currently selected into the device context). Zooming and panning are possible. Please note that panning is applied before zooming. (MFC users can use the CDC::GetSafeHdc() method to obtain a suitable device context handle from a CDC instance.)

Parameters

graphicContext	Handle to the device context of the destination window.
handles	true if handles are to be drawn.
zoomX	Magnification factor for zooming in or out in the horizontal direction. By default, the image is displayed in true scale.
zoomY	Magnification factor for zooming in or out in the vertical direction. Setting a 0 value (which is the default) will result in isotropic scaling (i.e. equal horizontal and vertical factors).

A frame can be drawn (using a device context) around an image or ROI, possibly with 9 sizing handles.

The current device context pen is used. Zooming and panning are possible. Please note that panning is applied before zooming.

(MFC users can use the CDC::GetSafeHdc() method to obtain a suitable device context handle from a CDC instance.)

Parameters

graphicContext	Handle to the device context of the destination window.
handles	true if handles are to be drawn.
zoomX	Magnification factor for zooming in or out in the horizontal direction. By default, the image is displayed in true scale.
zoomY	Magnification factor for zooming in or out in the vertical direction. Setting a 0 value (which is the default) will result in isotropic scaling (i.e. equal horizontal and vertical factors).
panX	Horizontal panning value expressed in pixels. By default, no panning occurs.

FirstSubROI()

eVision.EROIBW32f | None eVision.EROIBW32f.FirstSubROI

(

self

)

See GetFirstSubROI in the derived classes.

Deprecated

Deprecated due to the high runtime cost on all operations of maintaining a ROI hierarchy.

If a ROI hierarchy is necessary it is now recommended to maintain it outside of ROI and Image classes.

Deprecated in version 26.10. Scheduled to be removed in version 27.10.

Reimplemented from eVision.EBaseROI.

GetNextROI()

eVision.EROIBW32f | None eVision.EROIBW32f.GetNextROI	(		self,
		eVision.EBaseROI | None	startROI )

Returns the next ROI in the list starting at startROI or null if there is no next ROI.

Deprecated

Deprecated due to the high runtime cost on all operations of maintaining a ROI hierarchy.

If a ROI hierarchy is necessary it is now recommended to maintain it outside of ROI and Image classes.

Deprecated in version 26.10. Scheduled to be removed in version 27.10.

GetPixel()
