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 - Inspect the request and determine whether you are creating a new deck, recreating an existing deck, or editing one. - Set the slide size up front. Default to 16:9 (`LAYOUT_WIDE`) unless the source material clearly uses another aspect ratio. - Copy `assets/pptxgenjs_helpers/` into the working directory and import the helpers from there. - Build the deck in JavaScript with an explicit theme font, stable spacing, and editable PowerPoint-native elements when practical. - Run the bundled scripts from this skill directory or copy the needed ones into the task workspace. Render the result with `render_slides.py`, review the PNGs, and fix layout issues before delivery. - Run `slides_test.py` for overflow checks when slide edges are tight or the deck is dense. - Deliver the `.pptx`, the authoring `.js`, and any generated assets that are required to rebuild the deck. ## Authoring Rules - Set theme fonts explicitly. Do not rely on PowerPoint defaults if typography matters. - Use `autoFontSize`, `calcTextBox`, and related helpers to size text boxes; do not use PptxGenJS `fit` or `autoFit`. - Use bullet options, not literal `•` characters. - Use `imageSizingCrop` or `imageSizingContain` instead of PptxGenJS built-in image sizing. - Use `latexToSvgDataUri()` for equations and `codeToRuns()` for syntax-highlighted code blocks. - Prefer native PowerPoint charts for simple bar/line/pie/histogram style visuals so reviewers can edit them later. - For charts or diagrams that PptxGenJS cannot express well, render SVG externally and place the SVG in the slide. - Include both `warnIfSlideHasOverlaps(slide, pptx)` and `warnIfSlideElementsOutOfBounds(slide, pptx)` in the submitted JavaScript whenever you generate or substantially edit slides. - Fix all unintentional overlap and out-of-bounds warnings before delivering. If an overlap is intentional, leave a short code comment near the relevant element. ## Recreate Or Edit Existing Slides - Render the source deck or reference PDF first so you can compare slide geometry visually. - Match the original aspect ratio before rebuilding layout. - Preserve editability where possible: text should stay text, and simple charts should stay native charts. - If a reference slide uses raster artwork, use `ensure_raster_image.py` to generate debug PNGs from vector or odd image formats before placing them. ## Validation Commands Examples below assume you copied the needed scripts into the working directory. If not, invoke the same script paths relative to this skill folder. ``` # Render slides to PNGs for review python3 scripts/render_slides.py deck.pptx --output_dir rendered # Build a montage for quick scanning python3 scripts/create_montage.py --input_dir rendered --output_file montage.png # Check for overflow beyond the original slide canvas python3 scripts/slides_test.py deck.pptx # Detect missing or substituted fonts python3 scripts/detect_font.py deck.pptx --json ``` Load `references/pptxgenjs-helpers.md` if you need the helper API summary or dependency details.
