Image To Editable Ppt

Image To Editable PPT

Core Promise

Convert each source image into a PowerPoint slide that is editable where practical: text becomes text boxes, simple geometry becomes PowerPoint shapes, and complex visual areas remain cropped PNG/JPG assets placed at the matching coordinates. Always deliver the PPTX, VBA macro code, and a cropped-material folder.

Use this skill together with the presentations skill whenever creating or editing .pptx files.

Required Source Image Access

Before making a PPT or claiming any crop, confirm the user has provided an actual readable image file path, not only a chat preview.

If the image is only visible in chat and no local path/file data is available to tools, tell the user:

我能看到聊天里的图片预览，但代码工具不能读取它的原始像素文件，所以不能真实裁剪。请把图片保存到当前工作目录或你指定的文件夹，并告诉我完整文件路径，例如：
<你的工作目录>/source.png
然后我会从这个文件里裁剪素材并生成 PPT/VBA。

Do not proceed with exact cropping until the path exists and can be read.

Output Contract

Create a delivery folder named after the task, with this structure:

task-name/
├── pptx/
│   └── editable_rebuild.pptx
├── vba/
│   ├── rebuild_from_assets.bas
│   └── README_import.txt
├── assets/
│   ├── source/
│   └── crops/
├── analysis/
│   ├── image_map.json
│   └── reconstruction_notes.md
└── qa/
    └── render_check.png

The PowerPoint must open normally without requiring the VBA macro. The macro is an extra reconstruction artifact for users who want to run or modify the layout in PowerPoint VBA.

Workflow

1. Inspect each uploaded image before coding.

   • First confirm the actual image file is available on disk or in the tool context. If only a chat-rendered preview is visible and no source file path/data is accessible, stop and ask the user to provide the original image file or a local path before making the PPT or claiming any exact crops.
   • Identify canvas size, aspect ratio, visible margins, background style, text regions, repeated layout grids, charts, icons, logos, photos, screenshots, and decorative shapes.
   • Choose slide size from the image aspect ratio. Use wide 13.333 x 7.5 in for 16:9 images unless the source ratio clearly differs.

2. Decide editability by region.

   • Rebuild editable text as native text boxes.
   • Rebuild simple fills, strokes, lines, arrows, rectangles, circles, badges, and separators as native shapes.
   • Crop and embed complex regions: photos, product screenshots, maps, charts with dense marks, logos, illustrations, textures, gradients that are too costly to reproduce, and any element where fidelity matters more than editability.
   • If OCR is uncertain, keep the crop behind or beside an editable text approximation and note uncertainty in reconstruction_notes.md.

3. Extract assets.

   • Save the original images in assets/source/.
   • Save every raster-only region as assets/crops/slide##_element##_name.png.
   • Keep crop filenames stable and referenced by both the PPTX creation code and the VBA macro.
   • Record coordinates in analysis/image_map.json using source pixels plus normalized slide coordinates.

4. Build the PPTX.

   • Prefer the presentations skill and its render/verify workflow for PPTX generation.
   • Ensure text is editable, layered correctly, and sized to avoid overflow.
   • Use embedded crops only for raster regions, not for the whole slide unless the user explicitly asks for screenshot-only output.
   • Keep the original image as a temporary reference only if useful; remove or hide it before final delivery unless asked to include it.

5. Generate VBA.

   • Read references/vba_powerpoint_patterns.md when writing the macro.
   • Create vba/rebuild_from_assets.bas with a BuildEditableDeckFromAssets entry point.
   • Use relative asset paths when possible, or a PickAssetFolder helper when PowerPoint cannot resolve relative paths reliably.
   • Macro must create slide size, backgrounds, shapes, text boxes, image placements, and z-order in the same order as the PPTX.

6. Verify.

   • Render the PPTX and compare visually against the original image.
   • Check that major text blocks are selectable/editable in PowerPoint, not flattened into a single screenshot.
   • Run scripts/validate_delivery.py <delivery-folder> before final response.
   • Mention any areas intentionally preserved as crops.

Helper Scripts

Use these scripts from this skill directory:

python scripts/init_image_ppt_project.py --out <delivery-folder> <image1> [image2 ...]
python scripts/validate_delivery.py <delivery-folder>

init_image_ppt_project.py creates the required folder tree and a starter analysis/image_map.json with image dimensions.

validate_delivery.py checks that the expected PPTX, VBA, source images, crop folder, and analysis files exist.

Quality Rules

• Never deliver only a flattened screenshot PPT unless the user asks for that shortcut.
• Never describe a generated or approximated visual as a crop from the source image. Exact crops require the original image file or pixel data.
• Preserve visual fidelity by cropping hard raster regions instead of hallucinating dense graphics.
• Keep all visible text either editable or explicitly documented as a crop when OCR/reconstruction is unreliable.
• Match alignment, spacing, colors, and hierarchy closely enough that the rendered slide can be compared against the source image.
• Use Chinese filenames or comments only when the user wants Chinese-facing deliverables; otherwise keep code and paths ASCII-safe.
