1 # Pict-rs {#module-services-pict-rs}
3 pict-rs is a a simple image hosting service.
5 ## Quickstart {#module-services-pict-rs-quickstart}
7 the minimum to start pict-rs is
11 services.pict-rs.enable = true;
15 this will start the http server on port 8080 by default.
17 ## Usage {#module-services-pict-rs-usage}
19 pict-rs offers the following endpoints:
21 - `POST /image` for uploading an image. Uploaded content must be valid multipart/form-data with an
22 image array located within the `images[]` key
24 This endpoint returns the following JSON structure on success with a 201 Created status
29 "delete_token": "JFvFhqJA98",
30 "file": "lkWZDRvugm.jpg"
33 "delete_token": "kAYy9nk2WK",
34 "file": "8qFS0QooAn.jpg"
37 "delete_token": "OxRpM3sf0Y",
38 "file": "1hJaYfGE01.jpg"
44 - `GET /image/download?url=...` Download an image from a remote server, returning the same JSON
45 payload as the `POST` endpoint
46 - `GET /image/original/{file}` for getting a full-resolution image. `file` here is the `file` key from the
47 `/image` endpoint's JSON
48 - `GET /image/details/original/{file}` for getting the details of a full-resolution image.
49 The returned JSON is structured like so:
54 "content_type": "image/webp",
63 - `GET /image/process.{ext}?src={file}&...` get a file with transformations applied.
64 existing transformations include
65 - `identity=true`: apply no changes
66 - `blur={float}`: apply a gaussian blur to the file
67 - `thumbnail={int}`: produce a thumbnail of the image fitting inside an `{int}` by `{int}`
68 square using raw pixel sampling
69 - `resize={int}`: produce a thumbnail of the image fitting inside an `{int}` by `{int}` square
70 using a Lanczos2 filter. This is slower than sampling but looks a bit better in some cases
71 - `crop={int-w}x{int-h}`: produce a cropped version of the image with an `{int-w}` by `{int-h}`
72 aspect ratio. The resulting crop will be centered on the image. Either the width or height
73 of the image will remain full-size, depending on the image's aspect ratio and the requested
74 aspect ratio. For example, a 1600x900 image cropped with a 1x1 aspect ratio will become 900x900. A
75 1600x1100 image cropped with a 16x9 aspect ratio will become 1600x900.
77 Supported `ext` file extensions include `png`, `jpg`, and `webp`
79 An example of usage could be
81 GET /image/process.jpg?src=asdf.png&thumbnail=256&blur=3.0
83 which would create a 256x256px JPEG thumbnail and blur it
84 - `GET /image/details/process.{ext}?src={file}&...` for getting the details of a processed image.
85 The returned JSON is the same format as listed for the full-resolution details endpoint.
86 - `DELETE /image/delete/{delete_token}/{file}` or `GET /image/delete/{delete_token}/{file}` to
87 delete a file, where `delete_token` and `file` are from the `/image` endpoint's JSON
89 ## Missing {#module-services-pict-rs-missing}
91 - Configuring the secure-api-key is not included yet. The envisioned basic use case is consumption on localhost by other services without exposing the service to the internet.
