@dave3d Is there a way to tell the spell checker to ignore a whole file? In the pre-commit config or else where? |

You could disable spell checking within the file by putting in the comment: "// spell-check-disable" https://github.com/SimpleITK/CommentSpellCheck?tab=readme-ov-file#disabling-spell-checking or maybe adding the file name to the "exclude" line in the YAML file. |

There was a problem hiding this comment.
So Pythonic and makes the usage of views safer for users. Very nice work!
Some trivial spelling that can be ignored.
The ImageBuffer class maintains a reference the the python Image instance, which solves the dangling pointer for memory buffers with the prior _GetMemoryViewFromImage method.
Allow for implicit view as numpy arrays as read-only buffers which maintain a reference to the Python Image object. Implement PEP 688 for Python >= 3.12, by adding the __buffer__ method.
Useful functions to determine the class of pixel type. This is current in a private module and may be implemented C++ in the future. fix up for pixel types
The function was private and can be removed without deprecation.

Enables view and conversions to numpy arrays with the following:
References to the Python Image object are maintained.
COMPATIBILITY:
Images of vector pixel type with only 1 component now return memory views and arrays of n+1 dimensions. ( Previously the 1 size component dimension was dropped )
