Slides

Overview

Use PptxGenJS for slide authoring. Do not use python-pptx for deck generation unless the task is inspection-only; keep editable output in JavaScript and deliver both the .pptx and the source .js.

Keep work in a task-local directory. Only copy final artifacts to the requested destination after rendering and validation pass.

Bundled Resources

• assets/pptxgenjs_helpers/: Copy this folder into the deck workspace and import it locally instead of reimplementing helper logic.
• scripts/render_slides.py: Rasterize a .pptx or .pdf to per-slide PNGs.
• scripts/slides_test.py: Detect content that overflows the slide canvas.
• scripts/create_montage.py: Build a contact-sheet style montage of rendered slides.
• scripts/detect_font.py: Report missing or substituted fonts as LibreOffice resolves them.
• scripts/ensure_raster_image.py: Convert SVG/EMF/HEIC/PDF-like assets into PNGs for quick inspection.
• references/pptxgenjs-helpers.md: Load only when you need API details or dependency notes.

Workflow

1. Inspect the request and determine whether you are creating a new deck, recreating an existing deck, or editing one.
2. Set the slide size up front. Default to 16:9 (LAYOUT_WIDE) unless the source material clearly uses another aspect ratio.
3. Copy assets/pptxgenjs_helpers/ into the working directory and import the helpers from there.
4. Build the deck in JavaScript with an explicit theme font, stable spacing, and editable PowerPoint-native elements when practical.
