-# Lilo Stitcher API
-
-An ASP.NET Core Web API for stitching, cropping, and scaling tiled images (720×720).
-
-## Prerequisites
-
-* .NET 9.0 SDK
-* `ASSET_PATH_RO` environment variable containing the path to tiles directory (1,705 PNGs named A1.png…AE55.png)
-
-## Build & Run
-
-```bash
-cd lilo-stitcher
-dotnet clean
-dotnet run
-```
-
-By default, the API listens on `http://localhost:5243` and `https://localhost:7121` (see [`launchSettings.json`](https://null.formulatrix.dev/fikribahru/lilo-stitcher/src/branch/main/Properties/launchSettings.json)).
-
-## Usage
-
-**Endpoint:** `POST /api/image/generate`
-
-**Request Body (JSON):**
-
-```json
-{
-  "canvas_rect": "A1:H12",
-  "crop_offset": [0.25, 0.25],
-  "crop_size":   [0.5,  0.5],
-  "output_scale": 1.0
-}
-```
-
-**Example (using `curl`):**
-
-```bash
-curl -X POST http://localhost:5243/api/image/generate \
-     -H "Content-Type: application/json" \
-     -o output.png \
-     -d '{"canvas_rect":"A1:H12","crop_offset":[0.25,0.25],"crop_size":[0.5,0.5],"output_scale":1.0}'
-```
-
-The API will return a `image/png` containing the stitched, cropped, and scaled result.
