Detailed Description

The eVision.EImageBW32f class is used to represent rectangular regions of interest inside eVision.EBW32f gray-level images.

See ROIs.

Constructor & Destructor Documentation

__init__() [1/4]

None eVision.EImageBW32f.__init__

(

self

)

Constructs a eVision.EImageBW32f image.

Remarks:

The constructor with no arguments creates a zero-sized image. You can modify the image size by calling eVision.EBaseROI.SetSize method.

The sizing constructor constructs an image of the given size. See eVision.EBaseROI.SetSize for informations about the sizing restrictions.

The copy constructor copies all the supplied image properties (content, attributes, sub-ROIs...) into the current object. Note that if you used eVision.EBaseROI.UseExternalBuffer to assign an external buffer to the image, that buffer will not be copied, the resulting image will just point to the same buffer as the original.

The sizing constructor constructs an image of the given size. See eVision.EBaseROI.SetSize for informations about the sizing restrictions.

The copy constructor copies all the supplied image properties (content, attributes, sub-ROIs...) into the current object. Note that if you used eVision.EBaseROI.UseExternalBuffer to assign an external buffer to the image, that buffer will not be copied, the resulting image will just point to the same buffer as the original.

Parameters

width	The width, in pixels.
height	The height, in pixels.

__init__() [3/4]

None eVision.EImageBW32f.__init__	(		self,
		int	width,
		int	height,
		eVision.EBW32f	constant )

Constructs a eVision.EImageBW32f image.

Remarks:

The constructor with no arguments creates a zero-sized image. You can modify the image size by calling eVision.EBaseROI.SetSize method.

The sizing constructor constructs an image of the given size. See eVision.EBaseROI.SetSize for informations about the sizing restrictions.

The copy constructor copies all the supplied image properties (content, attributes, sub-ROIs...) into the current object. Note that if you used eVision.EBaseROI.UseExternalBuffer to assign an external buffer to the image, that buffer will not be copied, the resulting image will just point to the same buffer as the original.

Parameters

width	The width, in pixels.
height	The height, in pixels.
constant	Gray-level constant.

__init__() [4/4]

None eVision.EImageBW32f.__init__	(		self,
		eVision.EImageBW32f	other )

Constructs a eVision.EImageBW32f image.

Remarks:

Parameters

other

Another eVision.EImageBW32f object.

Member Function Documentation

InitializeFromUnalignedBuffer() [1/2]

None eVision.EImageBW32f.InitializeFromUnalignedBuffer	(		self,
		int	width,
		int	height,
		ctypes.c_void_p	buffer )

Initializes image from an unaligned buffer.

Remarks:

The image will be initialized to fit the width and height passed as arguments. The contents of the buffer will then be copied into the image. The buffer contents must be compatible with the pixel type of the image.

Parameters

width	Width of the image in the buffer.
height	Height of the image in the buffer.
buffer	Address of the buffer.

InitializeFromUnalignedBuffer() [2/2]

None eVision.EImageBW32f.InitializeFromUnalignedBuffer	(		self,
		int	width,
		int	height,
		ctypes.c_void_p	buffer,
		int	pitch )

Initializes image from an unaligned buffer.

Remarks:

The image will be initialized to fit the width and height passed as arguments. The contents of the buffer will then be copied into the image. The buffer contents must be compatible with the pixel type of the image.

Parameters

width	Width of the image in the buffer.
height	Height of the image in the buffer.
buffer	Address of the buffer.
pitch	Pitch of the buffer (in bytes). If omitted, the method assumes there is no padding (the pitch is assumed be equal (width * sizeOfAPixel))
