Backend — new /api/print/* router:
- POST /api/print/frame-fit: fit image to 4x6/5x7/8x10/11x14/16x20/20x24/24x36
and square sizes (4x4/8x8/12x12) at configurable DPI.
Three modes:
crop — center-crop to aspect ratio, Lanczos scale to print res (no AI)
extend — scale to fill one dimension, AI-inpaint the gap; mirror-fill fallback
smart — auto: extend if gap < 15% of frame dimension, else crop
Auto-detects orientation from image shape; respects explicit portrait/landscape.
- POST /api/print/upscale: Lanczos scale (always) or Real-ESRGAN (if installed)
- GET /api/print/frame-sizes: frame catalogue with pixel dimensions at 300dpi
- GET /api/print/upscale/available: reports whether Real-ESRGAN is installed
Frontend:
- modules/image/frame_fit.js: dialog with frame size, orientation, mode, DPI,
optional extend prompt; shows current image size; result as new layer option
- modules/image/upscale.js: dialog with scale factor (1.5–4×), method selector
(auto-hides AI option if Real-ESRGAN not available); result as new layer option
- config-menu.js: Fit to Frame... and Upscale... added under Image menu

Frontend:
- tools/ai_replace_selection.js: use any selection → remote inpaint with prompt
- modules/generate/text_to_image.js: Text → Image dialog (new layer or replace canvas)
- modules/generate/outpaint.js: Expand Canvas in any direction via remote provider
- modules/tools/ai_provider_settings.js: in-app provider config (OpenAI / InvokeAI /
ComfyUI / Replicate); persists to localStorage, pushes to POST /api/config at runtime
- config.js: register ai_replace_selection tool
- config-menu.js: add Generate menu (Text→Image, Outpaint); AI Provider Settings under Tools
- modules/help/about.js: updated credits (LaMa, rembg, SAM, InvokeAI, ComfyUI, OpenAI)
- api/capabilities.js: add refreshCapabilities() for post-save cache invalidation
Backend:
- routers/ai_tools.py: POST /api/config — apply provider settings at runtime
without restart (session-scoped, non-persistent; .env for permanence)

- Save layer or selection to personal library
- Browse library with category grouping and thumbnails
- Insert assets as new layers (double-click or Insert button)
- Delete unwanted assets
- Export library to JSON for backup
- Import library from JSON backup
- Assets stored in browser IndexedDB (persistent)
- Categories: General, Shapes, Borders, Icons, Templates, etc.
- New Image > Selection Effects submenu
- Invert Selection: Invert colors only within selected area
- Adjust Selection: Brightness/contrast/gamma on selection only
- Greyscale Selection: Convert just the selected area to greyscale
- All effects work with any selection tool (Smart Select, Brush Select, etc.)
- Useful for CNC depth maps where specific objects need different treatments
Frontend:
- Added "Remove Background (AI)" to Image menu
- Created remove_background.js module with dialog options
- Added removeBackground method to API service
Backend:
- Added /tools/remove-background-base64 endpoint for miniPaint frontend
- Uses rembg library for AI-powered background removal
Features:
- Automatically detects main subject and removes background
- Option to create as new layer or replace current
- Enables transparency mode after removal
- Works with any image layer
