`TiTiler.image` is a [titiler](https://github.com/developmentseed/titiler) extension to work with non-geo images.

## Installation

To install from PyPI and run:

```bash
# Make sure to have pip up to date
python -m pip install -U pip

python -m pip install titiler.image
```

To install from sources and run for development:

```bash
python -m pip install -e .
```

## Launch

```bash
python -m pip install uvicorn
python -m uvicorn titiler.image.main:app --reload
```

### Using Docker

```bash
git clone https://github.com/developmentseed/titiler-image.git
cd titiler-pgstac
docker-compose up --build tiler
```

It runs `titiler.image` using Gunicorn web server. To run Uvicorn based version:

```bash
docker-compose up --build tiler-uvicorn
```

## Factories

`titiler-image` provide multiple endpoint Factories (see https://developmentseed.org/titiler/advanced/tiler_factories/)

### MetadataFactory

#### Endpoints

- `/info?url={...}`

- `/metadata?url={...}`

```python
from fastapi import FastAPI
from titiler.image.factory import MetadataFactory

app = FastAPI()
meta = MetadataFactory()
app.include_router(meta.router)
```

### IIIFFactory

Specification: https://iiif.io/api/image/3.0/

#### Endpoints

- `/{identifier}/info.json`: IIIF Image Information Request

- `/{identifier}/{region}/{size}/{rotation}/{quality}.{format}`: IIIF Image Request

- `/{identifier}`: Redirect do the Image Information Request endpoint or return a simple IIIF viewer (based on headers `Accept` value)


```python
from fastapi import FastAPI
from titiler.image.factory import IIIFFactory

app = FastAPI()
iiif = IIIFFactory()
app.include_router(iiif.router)
```

### LocalTilerFactory

#### Endpoints

- `/tilejson.json?url={...}`: TileJSON document

- `/tiles/{z}/{x}/{y}[@{scale}x.{format}]?url={...}`: Tiles endpoint

- `/viewer?url={...}`: Simple local tiles viewer

```python
from fastapi import FastAPI
from titiler.image.factory import LocalTilerFactory

app = FastAPI()
local_tiles = LocalTilerFactory()
app.include_router(local_tiles.router)
```

### GeoTilerFactory

This is a lightweight version of `titiler.core.factory.TilerFactory`.

#### Endpoints

- `[/TileMatrixSetId]/tilejson.json?url={...}`: TileJSON document

- `/tiles[/TileMatrixSetId]/{z}/{x}/{y}[@{scale}x.{format}]?url={...}`: Tiles endpoint

- `[/{TileMatrixSetId}]/map?url={...}`: Simple dataset viewer

```python
from fastapi import FastAPI
from titiler.image.factory import GeoTilerFactory

app = FastAPI()
geo = GeoTilerFactory()
app.include_router(geo.router)
```

### All together

```python
app = FastAPI()

meta = MetadataFactory()
app.include_router(meta.router, tags=["Metadata"])

iiif = IIIFFactory(router_prefix="/iiif")
app.include_router(iiif.router, tags=["IIIF"], prefix="/iiif")

image_tiles = LocalTilerFactory(router_prefix="/image")
app.include_router(image_tiles.router, tags=["Local Tiles"], prefix="/image")

geo_tiles = GeoTilerFactory(
    reader=GCPSReader, reader_dependency=GCPSParams, router_prefix="/geo"
)
app.include_router(geo_tiles.router, tags=["Geo Tiles"], prefix="/geo")
```
