API

pict-rs offers four endpoints:

• POST /image for uploading an image. Uploaded content must be valid multipart/form-data with an image array located within the images[] key

  This endpoint returns the following JSON structure on success with a 201 Created status

  {
      "files": [
          {
              "delete_token": "JFvFhqJA98",
              "file": "lkWZDRvugm.jpg"
          },
          {
              "delete_token": "kAYy9nk2WK",
              "file": "8qFS0QooAn.jpg"
          },
          {
              "delete_token": "OxRpM3sf0Y",
              "file": "1hJaYfGE01.jpg"
          }
      ],
      "msg": "ok"
  }
  

• GET /image/download?url=... Download an image from a remote server, returning the same JSON payload as the POST endpoint

• GET /image/{file} for getting a full-resolution image. file here is the file key from the /image endpoint's JSON

• GET /image/{transformations...}/{file} get a file with transformations applied. existing transformations include

  • identity: apply no changes
  • blur{float}: apply a gaussian blur to the file
  • {int}: produce a thumbnail of the image fitting inside an {int} by {int} square An example of usage could be GET /image/256/blur3.0/asdf.png, which would create a 256x256px thumbnail and blur it

• DELETE /image/{delete_token}/{file} to delete a file, where delete_token and file are from the /image endpoint's JSON
