Member Function Documentation

◆ AdaptDataType()

static ImageView IOLink.ImageViewFactory.AdaptDataType	(	ImageView	view,
		DataType	type
	)

inlinestatic

Creates an ImageView from another view with given type. No memory is allocated by this operation. Capabilities of returned ImageView will depend on original ImageView, and will be restricted to (see #ImageCapability):

READ

WRITE One or many adapters will be added if necessary to convert from input view type to output View type. Data will be mapped to full output type range. For example, if given view is 16 bits with valueRange [1000, 2000] and type is uint8, input range [1000, 2000] will be mapped to output range [0, 255]. Input data range are read from view properties. Output range is specified type standard range. It can be retrieved with DataType::standardRange(type).

Parameters

view	The source image
type	The target datatype

Exceptions

InvalidArgument	If the view is null
InvalidArgument	If properties of input ImageView are not valid
InvalidArgument	If type cardinality is different of original type
InvalidArgument	If given type is not numeric
Error	if Input view does not support READ capability

◆ AdaptDynamicRange()

static ImageView IOLink.ImageViewFactory.AdaptDynamicRange	(	ImageView	view,
		DataType	type,
		Vector2d	inputRange,
		Vector2d	outputRange
	)

inlinestatic

Creates an ImageView from another view with given type by mapping dynamic range. No memory is allocated by this operation. Capabilities of returned ImageView will depend on original ImageView, and will be restricted to (see #ImageCapability):

READ
WRITE This method will map [inputRange[0], inputRange[1]] -> [outputRange[0], outputRange[1]] One or many adapters will be added if necessary to convert from input view type to output View type. Data will be mapped to full output type range. For example, if given view is 16 bits with valueRange [1000, 2000] and type is uint8 with input range [20, 50], input range [1000, 2000] will be mapped to output range [20, 50]. If input image contains value outside of given inputRange, these values will be linearly mapped outside of outputRange. For example, with [0, 1]->[0, 2], a value of -1 will be mapped to -2.

No clamp are done for values outside of type admissible values. Invalid ranges may lead to overflow

Parameters

view	Input view
type	Requested data type
inputRange	Range of data in input view
outputRange	Requested output range

Exceptions

InvalidArgument	If the view is null
InvalidArgument	If properties of input ImageView are not valid
InvalidArgument	If type cardinality is different of original type
InvalidArgument	If given type is not numeric

view MultiImage view which contains frames of same format and shape

Exceptions

InvalidArgument If the view is null

InvalidArgument If there is no frame in the MultiImageView

InvalidArgument if all frames don't have same shape and datatype

◆ Stack() [2/3]

static ImageView IOLink.ImageViewFactory.Stack	(	MultiImageView	view,
		ImageDimension	newDimension
	)

inlinestatic

Creates an ImageView from a multiImageView by agglomerating frames into a new given dimension. No memory is allocated by this operation. Capabilities of returned ImageView will depend on original ImageViews contained in MultiImageView, and will be restricted to (see #ImageCapability):

READ

WRITE (i.e. a given multiImageView containing 2D frames (with Imagetype = IMAGE) and a given dimension equal to SEQUENCE will give as result a IMAGE_SEQUENCE - video - containing all the images) Concatenation of frames is possible only if their shapes, datatypes and ImageTypes are equal. A warning will be raised if given frames have an ImageType = UNKNOWN, because the given ImageDimension is ignored in this case, but the stack is still applied, and output ImageType will be UNKNOWN If the given dimension is CHANNEL, and more than one frame is stacked, ImageInterpretation will become UNKNOWN. Underlying adapter use multithreading to accelerate the data access. To configure or deactivate it, use prototype with threadCount as argument.

Parameters

view	MultiImage view which contains frames of same format and shape
newDimension	interpretation of the new dimension to create

Exceptions

InvalidArgument	If the view is null
InvalidArgument	if all frames don't have same shape and datatype
InvalidArgument	if given new dimension already exist in given frames
InvalidArgument	if all frames don't have the same interpretation of axes

Examples: VolumeFromStack.cs.

◆ Stack() [3/3]

static ImageView IOLink.ImageViewFactory.Stack	(	MultiImageView	view,
		ImageDimension	newDimension,
		uint	threadCount
	)

inlinestatic

Creates an ImageView from a multiImageView by agglomerating frames into a new given dimension. No memory is allocated by this operation. Capabilities of returned ImageView will depend on original ImageViews contained in MultiImageView, and will be restricted to (see #ImageCapability):

READ

WRITE (i.e. a given multiImageView containing 2D frames (with Imagetype = IMAGE) and a given dimension equal to SEQUENCE will give as result a IMAGE_SEQUENCE - video - containing all the images) Concatenation of frames is possible only if their shapes, datatypes and ImageTypes are equal. A warning will be raised if given frames have an ImageType = UNKNOWN, because the given ImageDimension is ignored in this case, but the stack is still applied, and output ImageType will be UNKNOWN If the given dimension is CHANNEL, and more than one frame is stacked, ImageInterpretation will become UNKNOWN. Underlying adapter can use multithreading to accelerate the data access. By default (0), the thread count is automatically determined, but you can also force the thread count to use (value greater than 1). Setting a thread count to 1 will deactivate multithreading.

Parameters

view	MultiImage view which contains frames of same format and shape
newDimension	interpretation of the new dimension to create
threadCount	Number of threads to use for DataAccess

Exceptions

InvalidArgument	If the view is null
InvalidArgument	If there is no frame in the MultiImageView
InvalidArgument	if all frames don't have same shape and datatype
InvalidArgument	if given new dimension already exist in given frames
InvalidArgument	if all frames don't have the same interpretation of axes

◆ SubSample()

static ImageView IOLink.ImageViewFactory.SubSample	(	ImageView	image,
		uint	step
	)

inlinestatic

Create a sub-sampled imageView from original. No memory is allocated by this operation. Capabilities of returned ImageView will be resctriced to (see #ImageCapability):

READ

Parameters

image	ImageView to sub-sample
step	level of sub-sampling to apply

New ImageView is created by picking one sample for every step samples of original ImageView. A step of 1 will give the same Image as the original

Returns: a Sub-Sampled ImageView from original ImageView

Exceptions

InvalidArgument	If the image is null
InvalidArgument	If properties of input ImageView are not valid
InvalidArgument	If step is 0 or not compatible with ImageView shape
Error	If input image does not support READ capability

◆ Uniform() [1/2]

static ImageView IOLink.ImageViewFactory.Uniform	(	VectorXu64	shape,
		DataType	type,
		System::Object	value
	)

inlinestatic

Create an image with uniform value. No memory is allocated by this operation. Returned ImageView has following capabilities (see #ImageCapability):

READ This image doesn't consume memory, so you can create an image as big as you want.

Parameters

shape	The shape of the image (its dimension and sizes in all dimensions)
type	The type of data contained in that view.
value	Buffer should correspond to given DataType. If null is given, image is filled with zeros.

◆ Uniform() [2/2]

static ImageView IOLink.ImageViewFactory.Uniform	(	VectorXu64	shape,
		DataType	type,
		System::Object	value,
		ImageProperties	properties,
		ReadonlyMetadataNode	metadata
	)

inlinestatic

Create an image with uniform value. No memory is allocated by this operation. Returned ImageView has following capabilities (see #ImageCapability):

READ This image doesn't consume memory, so you can create an image as big as you want.

Parameters

shape	The shape of the image (its dimension and sizes in all dimensions)
type	The type of data contained in that view.
value	Buffer should correspond to given DataType. If null is given, image is filled with zeros.
properties	Optional properties. If null, default properties are generated.
metadata	Optional metadata. If null, no metadata are generated.

Exceptions

InvalidArgument If given properties are not compatible with given shape and type

The documentation for this class was generated from the following file:

Release/net/generated/ImageViewFactory.cs

InvalidArgument	If the source is null
Error	If the input ImageView does not support READ capability
InvalidArgument	If properties of input ImageView are not valid
