monai.deploy.operators.PNGConverterOperator

class monai.deploy.operators.PNGConverterOperator(fragment, *args, output_folder, **kwargs)

Bases: holoscan.core.Operator

This operator writes out a 3D Volumetric Image to to a file folder in a slice by slice manner.

Named input:

image: Image object or numpy ndarray

Named output:

None

File output:

Generated PNG image file(s) saved in the provided output folder.

Class to write out a 3D Volumetric Image to a file folder in a slice by slice manner.

Parameters

• fragment (Fragment) – An instance of the Application class which is derived from Fragment.

• output_folder (str or Path) – The folder for saving the generated DICOM instance file.

Methods

__init__(fragment, *args, output_folder, …)	Class to write out a 3D Volumetric Image to a file folder in a slice by slice manner.
add_arg(*args, **kwargs)	Overloaded function.
compute(op_input, op_output, context)	Default implementation of compute
convert_and_save(image, path)	extracts the slices in originally acquired direction (often axial) and saves them in PNG format slice by slice in the specified directory
initialize()	Default implementation of initialize
setup(spec)	Default implementation of setup method.
start()	Default implementation of start
stop()	Default implementation of stop

property name

__init__(fragment, *args, output_folder, **kwargs)

Class to write out a 3D Volumetric Image to a file folder in a slice by slice manner.

Parameters

• fragment (Fragment) – An instance of the Application class which is derived from Fragment.

• output_folder (str or Path) – The folder for saving the generated DICOM instance file.

add_arg(*args, **kwargs)

Overloaded function.

1. add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.Arg) -> None

Add an argument to the component.

2. add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.ArgList) -> None

Add a list of arguments to the component.

3. add_arg(self: holoscan.core._core.Operator, **kwargs) -> None

Add arguments to the component via Python kwargs.

4. add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.Condition) -> None

5. add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.Resource) -> None

Add a condition or resource to the Operator.

This can be used to add a condition or resource to an operator after it has already been constructed.

argholoscan.core.Condition or holoscan.core.Resource

The condition or resource to add.

property args

The list of arguments associated with the component.

arglist : holoscan.core.ArgList

compute(op_input, op_output, context)

Default implementation of compute

property conditions

Conditions associated with the operator.

convert_and_save(image, path)

extracts the slices in originally acquired direction (often axial) and saves them in PNG format slice by slice in the specified directory

property description

YAML formatted string describing the operator.

property fragment

The fragment that the operator belongs to.

name : holoscan.core.Fragment

property id

The identifier of the component.

The identifier is initially set to -1, and will become a valid value when the component is initialized.

With the default executor (holoscan.gxf.GXFExecutor), the identifier is set to the GXF component ID.

id : int

initialize()

Default implementation of initialize

property name

The name of the operator.

name : str

property operator_type

The operator type.

holoscan.core.Operator.OperatorType enum representing the type of the operator. The two types currently implemented are native and GXF.

property resources

Resources associated with the operator.

setup(spec)

Default implementation of setup method.

start()

Default implementation of start

stop()

Default implementation of stop
