Pull Request Overview

This pull request adds a new Python test file to verify the behavior of LinearImageFunction’s various IsInsideBuffer overloads as wrapped by ITK.

• Introduces a test script that exercises list, continuous index, and point-based inputs to IsInsideBuffer.
• Ensures that the Python wrapping for LinearImageFunction works as intended.

[nitpick] The trailing '*/' appears to be an artifact from another language's comment style. Consider removing it to maintain consistency with Python comment formatting.

Spotted immediately by a fresh set of eyes 😄

I copied this from another test, so this is not an isolated instance.

On the CI, the test fails with a different error message:

Traceback (most recent call last):
  File "/Users/runner/work/ITK/ITK/Modules/Core/ImageFunction/wrapping/test/itkLinearImageFunctionWrappingTest.py", line 23, in <module>
    interp = itk.LinearInterpolateImageFunction.New(image)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/Users/runner/work/ITK/ITK/build/Wrapping/Generators/Python/itk/support/template_class.py", line 751, in New
    raise itk.TemplateTypeError(self, input_type)
itk.support.extras.TemplateTypeError: itk.LinearInterpolateImageFunction is not wrapped for input type `None`.

To limit the size of the package, only a limited number of
types are available in ITK Python. To print the supported
types, run the following command in your python environment:

    itk.LinearInterpolateImageFunction.GetTypes()

Possible solutions:
* If you are an application user:
** Convert your input image into a supported format (see below).
** Contact developer to report the issue.
* If you are an application developer, force input images to be
loaded in a supported pixel type.

    e.g.: instance = itk.LinearInterpolateImageFunction[itk.Image[itk.SS,2], itk.D].New(my_input)

* (Advanced) If you are an application developer, build ITK Python yourself and
turned to `ON` the corresponding CMake option to wrap the pixel type or image
dimension you need. When configuring ITK with CMake, you can set
`ITK_WRAP_${type}` (replace ${type} with appropriate pixel type such as
`double`). If you need to support images with 4 or 5 dimensions, you can add
these dimensions to the list of dimensions in the CMake variable
`ITK_WRAP_IMAGE_DIMS`.

Supported input types:

itk.Image[itk.SS,2]
itk.Image[itk.UC,2]
itk.Image[itk.F,2]
itk.Image[itk.Vector[itk.F,2],2]
itk.Image[itk.CovariantVector[itk.F,2],2]
itk.Image[itk.RGBPixel[itk.UC],2]
itk.Image[itk.RGBAPixel[itk.UC],2]
itk.Image[itk.SS,3]
itk.Image[itk.UC,3]
itk.Image[itk.F,3]
itk.Image[itk.Vector[itk.F,3],3]
itk.Image[itk.CovariantVector[itk.F,3],3]
itk.Image[itk.RGBPixel[itk.UC],3]
itk.Image[itk.RGBAPixel[itk.UC],3]
itk.PhasedArray3DSpecialCoordinatesImage[itk.F]
itk.PhasedArray3DSpecialCoordinatesImage[itk.UC]
