Default: 0.0.0.0:8080 [env: PICTRS_ADDR=] [default: 0.0.0.0:8080] -f, --format An optional image format to convert all uploaded files into, supports 'jpg' and 'png' [env: PICTRS_FORMAT=] -m, --max-file-size Specify the maximum allowed uploaded file size (in Megabytes) [env: PICTRS_MAX_FILE_SIZE=] [default: 40] -p, --path The path to the data directory, e.g. data/ [env: PICTRS_PATH=] -w, --whitelist ... An optional list of filters to whitelist, supports 'identity', 'thumbnail', and 'blur' [env: PICTRS_FILTER_WHITELIST=] ``` #### Example: Running on all interfaces, port 8080, storing data in /opt/data ``` $ ./pict-rs -a 0.0.0.0:8080 -p /opt/data ``` Running locally, port 9000, storing data in data/, and converting all uploads to PNG ``` $ ./pict-rs -a 127.0.0.1:9000 -p data/ -f png ``` Running locally, port 8080, storing data in data/, and only allowing the `thumbnail` and `identity` filters ``` $ ./pict-rs -a 127.0.0.1:8080 -p data/ -w thumbnail identity ``` #### Docker Run the following commands: ``` # Create a folder for the files (anywhere works) mkdir ./pict-rs cd ./pict-rs mkdir -p volumes/pictrs sudo chown -R 991:991 volumes/pictrs wget https://git.asonix.dog/asonix/pict-rs/raw/branch/master/docker/prod/docker-compose.yml sudo docker-compose up -d ``` #### Docker Development Run the following to develop in docker: ``` git clone https://git.asonix.dog/asonix/pict-rs cd pict-rs/docker/dev docker-compose up --build ``` ### 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 ```json { "files": [ { "delete_token": "JFvFhqJA98", "file": "lkWZDRvugm.jpg" }, { "delete_token": "kAYy9nk2WK", "file": "8qFS0QooAn.jpg" }, { "delete_token": "OxRpM3sf0Y", "file": "1hJaYfGE01.jpg" } ], "msg": "ok" } ``` - `POST /import` for uploading an image while preserving the filename. This should not be exposed to the public internet, as it can cause naming conflicts with saved files. The upload format and response format are the same as the `POST /image` endpoint. - `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 - `thumbnail{int}`: produce a thumbnail of the image fitting inside an `{int}` by `{int}` square An example of usage could be ``` GET /image/thumbnail256/blur3.0/asdf.png ``` which would create a 256x256px thumbnail and blur it - `DELETE /image/{delete_token}/{file}` or `GET /image/{delete_token}/{file}` to delete a file, where `delete_token` and `file` are from the `/image` endpoint's JSON ## Contributing Feel free to open issues for anything you find an issue with.
