# @tutti-os/workbench-electron
|
|
|
|
Electron main-process helpers for Workbench previews.
|
|
|
|
The package owns two product-neutral mechanics:
|
|
|
|
- serial `webContents.capturePage()` capture, renderer-rectangle cropping,
|
|
full-size Genie output, bounded Dock resizing, timeout handling, and
|
|
empty-image handling
|
|
- validated, bounded, atomic filesystem storage for Dock preview data URLs
|
|
|
|
The consuming desktop host still owns IPC authorization, BrowserWindow
|
|
ownership, the cache directory (for example, a path below Electron
|
|
`app.getPath("userData")`), and product logging.
|
|
|
|
```ts
|
|
import {
|
|
captureWorkbenchPreviewImages,
|
|
createWorkbenchDockPreviewCacheStore
|
|
} from "@tutti-os/workbench-electron";
|
|
|
|
const previewImages = await captureWorkbenchPreviewImages({
|
|
contentSize: ownerWindow.getContentBounds(),
|
|
maxHeight: 170,
|
|
maxWidth: 260,
|
|
rect: rendererRect,
|
|
webContents: ownerWindow.webContents
|
|
});
|
|
|
|
const cache = createWorkbenchDockPreviewCacheStore({
|
|
directory: dockPreviewCacheDirectory
|
|
});
|
|
|
|
if (previewImages) {
|
|
await cache.write({ dataUrl: previewImages.dockPreviewImageUrl, key });
|
|
}
|
|
```
|
|
|
|
`captureWorkbenchPreviewImages` calls `capturePage()` once. The cropped native
|
|
image becomes the Genie image; a resized copy becomes the Dock preview.
|
|
`captureWorkbenchDockPreview` remains available for consumers that only need
|
|
the bounded Dock image.
