XiaoBei Image to VBA

小北在读研出品的 academic image-to-vba reconstruction skill. The workflow focuses on editable Office Shapes first, with carefully labeled raster crops only when complex scientific artwork should be preserved.

Output Language

All analysis, manifest tables, self-check reports, run reports, and conversational responses produced by this skill MUST be written in Simplified Chinese (简体中文). This includes:

视觉拆解、元素清单、坐标说明、自检结论、运行报告、给用户的最终回复。
VBA 代码内的注释也使用中文（例如 ' 标题区域背景），便于用户后续维护。

仅以下内容保留英文原样，不要翻译：

VBA 关键字、API 名、属性名（Sub、Shapes.AddShape、Fill.ForeColor.RGB 等）。
形状名前缀 AITVBA_ 与脚本路径、文件名。
颜色十六进制值与 RGB(...) 调用本身。

如果用户在对话里明确要求换成英文或其它语言，则按用户指定的语言输出，但 manifest 字段名仍保留英文 key 以便机器解析。

Purpose

Convert a reference image into a complete, runnable Office VBA macro that reconstructs the visual using editable Shapes, TextBoxes, Lines, Freeforms, fills, gradients, transparency, shadows, and ZOrder. When the image contains complex, distinctive graphic elements that would become noisy or low-value if rebuilt as hundreds of shapes, preserve those elements as cropped local image assets and reconstruct the surrounding structure with editable VBA Shapes. The core loop is: image -> environment detection -> visual decomposition -> editable-vs-preserved element plan -> Office coordinate model -> VBA Shapes code and cropped assets -> run or prepare the macro in the available presentation app -> self-check -> iterative correction.

Prefer editable Office Shapes for structure, labels, arrows, boxes, chart scaffolds, and readable text. Preserve complex graphic elements only as local cropped assets when that improves fidelity and keeps the VBA maintainable. Do not embed the full source image as a shortcut unless the user explicitly permits it or chooses the background-image-assisted option for complex photos. A PNG/JPEG/PDF preview is never the final deliverable for this skill; it is only allowed as a diagnostic screenshot after an editable Office reconstruction has been produced or attempted.

Default Deliverable Contract

When the user provides an image and asks for reconstruction, the default target is a presentation deck unless another Office host is explicit. Prefer Microsoft PowerPoint automation when available, but support WPS users and no-local-office users with a truthful fallback path. The agent must produce:

A complete VBA macro file or code block that reconstructs the image with editable Office Shapes.
Any preserved local image assets needed for hybrid reconstruction, with clear labels showing they are not editable Shapes.
A presentation file created from that macro when local automation is available, or a clear statement that local presentation automation was blocked or unsupported.
The generated deck opened for the user when local PowerPoint/WPS opening is available.
A short run report that says whether the macro was executed, whether the deck opened, and where the generated .bas / .pptx / .pptm files are located.

Do not satisfy an image-to-VBA request by generating only a PNG image, raster preview, static screenshot, or visual mockup. If a preview image is useful, create it only in addition to the editable VBA/PPT deliverables.

Hybrid Preservation Mode

Use hybrid preservation when any of the hard triggers below fire. Do not rely on subjective judgment about whether the result "looks cluttered" — model self-assessment is biased toward editable reconstruction, which causes complex artwork to be redrawn poorly. The goal is to preserve high-complexity artwork while keeping the diagram's editable structure editable.

Hard preservation triggers (hit any one → the element MUST be preserved as a raster crop):

The element is a microscopy image, 3D render, real photograph, or photo-realistic illustration.
The element contains photo-grade gradients, textures, noise, or organic shading that cannot be matched by a few solid fills or simple gradients.
The element is a logo, trademarked mark, or branded artwork.
A faithful editable reconstruction would require more than ~15 Shapes for that single element.
The element is hand-drawn, painterly, or has stroke-width variation that cannot be matched by simple Line/Freeform.
The user explicitly named the element as "keep as image", "保留", "不拆", or equivalent.

If none of the triggers fire, treat the element as editable. If a trigger fires but the user demanded "all editable", explain the fidelity tradeoff first and get permission before redrawing.

Classify every visible element into one of three buckets:

Editable Shapes: text, arrows, boxes, connectors, axes, callouts, tables, UI panels, simple icons, repeated markers, and diagram scaffolds.
Preserved raster elements: distinctive illustrations, logos, scientific renderings, microscopy/photo crops, 3D objects, complex texture patches, dense molecular/mesh graphics, screenshots inside device frames, and hand-drawn/artistic elements whose shape-by-shape reconstruction would be noisy.
Background/base: plain solid/gradient backgrounds should be rebuilt as shapes; full-image background insertion is allowed only when the user explicitly asks for it or the source is photo-like.

Hybrid rules:

Preserve only the smallest useful crop around each complex element; do not insert the entire source image just to preserve a small object.
Put preserved assets behind or between editable layers according to the original z-order.
Recreate nearby labels, arrows, boxes, highlights, and callouts as editable VBA objects even when they overlap preserved artwork.
Name preserved image shapes with the generated prefix, for example AITVBA_Raster_Microscope_01.
Save cropped assets next to the generated VBA/deck, preferably under an assets/ subdirectory.
In the final response, list preserved elements separately from editable elements so the user knows which parts remain raster.
If the user requests "all editable", do not use preserved raster elements unless you first explain the fidelity tradeoff and get permission.

保留元素的几何契约 (Preservation Geometry Contract)

保留元素出现"裁错 / 变形 / 缩放比例不对"是 hybrid 模式最常见的失败。下面这套契约是硬性的,违反任何一条都视为本轮 render-verify 不通过,必须回到 manifest 修正。

裁剪 bbox 必须等于 manifest bbox_px,不准 padding,不准外扩,不准内缩
- 调用 scripts/crop_preserved_elements.py 时,传入的坐标必须与 manifest 中该元素的 bbox_px 完全一致(整数像素)。
- 不要为了"美观"或"留出阴影"自行扩边。如果原图边界外有阴影/光晕需要保留,那应在 manifest 里就把 bbox_px 扩到包含阴影的范围,而不是裁的时候临时加。
- 裁出来的 PNG 必须保留原图 alpha 通道(若有),不要预先合成到白底。
插入时必须保持裁剪图自身的宽高比
- 在 VBA 里写 Shapes.AddPicture 后,只能用 ratio-safe 缩放:已知裁剪图原始像素宽高 cw_px, ch_px,目标插入区域宽高 tw_pt, th_pt,则:
  - s = min(tw_pt / cw_px, ch_px > 0 ? th_pt / ch_px : 1)
  - 实际插入的形状宽 = cw_px * s,高 = ch_px * s
- 严禁直接用 Width = X : Height = Y 把图片强行拉到 manifest 的目标尺寸,除非目标尺寸恰好与裁剪图等比。一旦目标 bbox 与裁剪源比例不一致,要么调整目标 bbox 使之与源等比,要么在目标区域内居中留白。
- 不允许给 AddPicture 之后再设置 LockAspectRatio = msoFalse 然后独立改宽高。
裁剪图与目标 bbox 的比例必须一致
- manifest 中保留元素的 bbox_px 既描述源图坐标,也决定目标 bbox 的宽高比。
- 如果裁出来的 PNG 实际宽高比与 manifest 的 bbox_px 比例偏差超过 ±2%,说明裁剪坐标错了,必须重新裁,而不是在插入时拉伸去"对齐"。
不允许旋转 / 翻转 / 任意 freeform 蒙版
- 默认 Rotation = 0,FlipH = msoFalse,FlipV = msoFalse。除非原图本来就是斜的,且 manifest 里该行显式给出了 rotation_deg 字段,否则不许动。
- 不要给保留图片套圆角矩形蒙版、椭圆蒙版、freeform 蒙版,这会改变它的视觉形状。需要圆角的,只能在 manifest 里把元素本身标为 editable,而不是把矩形裁剪强行变形。
插入位置使用 ratio-safe 坐标转换
- 用第 3 节的 scale / offset_x_pt / offset_y_pt 公式把 bbox_px 的 (x, y) 转成插入点 (Left, Top)。
- 不要用独立 X/Y 拉伸的版本,即使画布与原图同比也优先用 ratio-safe 形式,避免一处偷懒导致其它元素错位。
裁剪资产的命名与可追溯
- 文件名 = assets/<id>_<语义短名>.png,例如 assets/R03_microscope_left.png。
- 在 manifest 中保留该文件的 SHA-1 前 8 位或文件大小,render-verify 闭环里若某个保留元素差异大,先核对这一行哈希是否变了,排除"裁了又被覆盖"的情况。

保留元素自检 (额外的第 3.5 项 self-check)

在第 6 节 Mandatory Self-Checks 的"Preservation check"基础上,每一轮 render-verify 都额外运行下面四问,任何一问回答不出"是",该元素就不算合格:

这张裁剪图的宽高比 (cw_px / ch_px) 与 manifest bbox_px 的宽高比之差 < 2% 吗?
VBA 中该 AddPicture 之后的 Shape.Width / Shape.Height 比值与裁剪图原始比值之差 < 2% 吗?
该形状的 Rotation/FlipH/FlipV 是否与 manifest 显式声明一致(默认 0/false/false)?
渲染图中该形状的边界与原图中对应区域的边界,在 ratio-safe 映射后误差是否 < 画布短边的 2%?

不达标时,优先调整 manifest 的 bbox_px 与 crop_path,而不是在 VBA 里硬拉尺寸。

Environment Compatibility

Before trying to materialize a deck, identify the user's local runtime. Use scripts/detect_office_environment.py when local shell access is available; otherwise infer from the user's stated OS and installed office suite.

Choose the delivery path in this order:

Windows + Microsoft PowerPoint: generate .bas, run scripts/vba_lint.py, then try scripts/run_powerpoint_vba_windows.ps1. Report if PowerPoint Trust Center blocks VBA import.
macOS + Microsoft PowerPoint: generate .bas, run scripts/vba_lint.py, then try scripts/run_powerpoint_vba_macos.py. Report if AppleScript automation or Office macro security blocks execution.
WPS Presentation / WPS Office only: generate conservative PowerPoint-compatible VBA and a .bas file. Do not assume automatic VBA import/run is available. If WPS can be opened locally, open it and provide WPS-specific manual import/run steps. If WPS macro support is absent or unverified, say that plainly.
No local presentation app or unsupported platform: still generate the .bas VBA source. When feasible, also generate an editable .pptx fallback from the same shape plan, clearly labeled as a non-VBA fallback. Do not substitute a PNG as the final output.

Use WPS-compatible mode when WPS is the only available app:

Prefer basic Shapes, Lines, TextBoxes, solid fills, RGB colors, simple transparency, and simple shadows.
Avoid depending on advanced PowerPoint-only effects, complex TextFrame2 behavior, gradient stops, and macro security settings unless verified locally.
Save outputs in Microsoft-compatible formats (.bas, .pptx, .pptm) rather than WPS-only formats unless the user asks otherwise.
Label WPS results as compatibility-targeted, not fully PowerPoint-verified, unless they were actually opened and run in WPS.

Workflow

1. Input Recognition

Identify the target Office host:

Use PowerPoint when the user does not specify a host.
Use Excel when the user asks for a worksheet, dashboard, spreadsheet, chart sheet, grid, or Excel Shapes.
Use Word when the user asks for a document page, report, Word canvas, or inline/anchored drawing.

Ask a concise clarification only when the target host materially changes the solution and cannot be inferred. Otherwise proceed with the default presentation target, detect the available runtime, and attempt the best supported create/open path.

Classify the source image:

Vector/flat graphic: icons, diagrams, simple logos, flowcharts, infographics. Aim for high-fidelity editable shape reconstruction.
UI screenshot/poster: cards, bars, text, panels, tables, app screens. Aim for detailed reconstruction with editable text and shape groups.
Mixed scientific/academic figure with complex artwork plus labels: default to hybrid preservation for the complex artwork and editable reconstruction for text, arrows, boxes, connectors, legends, and callouts.
Complex photo/texture/person: explain limits. Offer:
- A. Pure VBA Shapes approximate reconstruction.
- B. Hybrid preservation of local crops plus editable VBA overlays.
- C. Use the image as a full background and add editable VBA overlays.

2. Image Parsing

Inspect the image before coding. Record:

Canvas ratio, orientation, approximate pixel dimensions, and target Office canvas size.
Background: solid, gradient,
