pptx-html-fidelity-audit

To fix layout drift during HTML to PPTX export, you audit the presentation geometry and typography. This process extracts actual PowerPoint shape positions and text details to compare against the HTML source, identifying and correcting footer overlap, cropped content, and inconsistent layouts.

Clipped text and footer collisions in python-pptx exports occur when geometry validation and footer rail enforcement are missing. Auditing the slide layout applies cursor-based flow control and geometry verification to prevent these recurring export failures.

To preserve italic styling and font fallback when converting HTML to PPTX, perform a typography preservation check. This detects HTML-to-PPTX formatting loss and repairs script-specific typography details to ensure the exported deck matches the original source.

python-pptx supports validating hero slide centering and footer rails through geometry verification. By extracting actual PowerPoint shape geometry, you can apply footer rail enforcement and verify layout regression to ensure exported slides match the intended design.

The best way to debug PPTX export fidelity issues is to run a layout audit comparing the exported file against the HTML deck. This identifies root causes of visual and structural drift by extracting shape geometry, text content, and typography details for direct verification.
