Issue with filling nitf_BandInfo **bandInfo in ImageSubheader

[samrat-boda]

Hello,

I am currently working with the NITRO library for handling NITF files and am encountering an issue when trying to populate the nitf_BandInfo **bandInfo field within ImageSubheader.

Environment:

• Language: Python
• Library: NITRO
• Relevant Files: nitro/modules/c/nitf/include/nitf/ImageSubheader.h and nitro/modules/c/nitf/include/nitf/BandInfo.h

Issue Description:
The ImageSubheader.h file defines most image subheader fields as type nitf_Field, for example:

nitf_Field *numRows;
nitf_Field *numCols;

In Python, I have managed to populate these fields successfully:

segment.subheader['numrows'] = height
segment.subheader['numcols'] = width

I'm struggling with the field nitf_BandInfo **bandInfo. The nitf_BandInfo is a struct defined in nitro/modules/c/nitf/include/nitf/BandInfo.h. I've attempted to fill this field but encountered difficulties.

Questions:

1. How should I properly instantiate and assign values to nitf_BandInfo **bandInfo from Python?
2. Is there a specific method or part of the API that facilitates handling pointers to structures in Python?
