X Title: Add full alt-text (title and description) support for pictures and inline shapes by EwoutH · Pull Request #1530 · python-openxml/python-docx

Description: Builds on #227 and #317. Summary This PR introduces first-class support for Word Alt Text in python-docx. Users can now set and read both the Alt Text Title and Alt Text Description (as shown in Word’s Accessibility pane) directly through the API when inserting or editing pictures. Motive Previously, python-docx did not expose a clean API for working with image alternative text. Users had to manually manipulate XML to set or retrieve attributes (title, descr). This enhancement improves accessibility workflows and enables automated tools (e.g., alt-text generators) to embed compliant descriptions directly into Word documents. Implementation CT_NonVisualDrawingProps (oxml/shape.py): Added optional attributes title and descr. CT_Inline.new() / new_pic_inline(): Accept and apply title / descr to . StoryPart.new_pic_inline(): Added title and descr parameters and forwarded them to CT_Inline.new_pic_inline(). Run.add_picture() and Document.add_picture(): Updated to accept and pass through title and descr for inline pictures. InlineShape (shape.py): Added new alt_text and alt_title properties for convenient read/write access to docPr.descr and docPr.title. Usage Examples from docx import Document from docx.shared import Inches doc = Document() # Insert an image with alt text doc.add_picture( "chart.png", width=Inches(5), descr="Line chart showing sales growth from 2020 to 2024.", title="Sales Growth Chart" ) # Access or modify alt text of an existing shape shape = doc.inline_shapes[0] print(shape.alt_text) # "Line chart showing sales growth from 2020 to 2024." shape.alt_text = "Updated alt text description." shape.alt_title = "Updated title." doc.save("report_with_alt_text.docx") Additional Notes Verified functionality using a test script that inserted an image, saved, reloaded, and confirmed alt_title and alt_text persisted correctly. No breaking API changes; title and descr are optional. Works across all story parts (document, headers, footers). Backwards compatible with existing documents. Enables accessibility tooling, automated captioning, and alt-text validation in Word documents.
