Configuration

thumbor’s configuration file is just a regular python script that gets loaded by thumbor.

In order to get a commented configuration file, just run:

thumbor-config > ./thumbor.conf

Override config through environment variable

It is possible override string configs through environment variables. This is possible because thumbor uses derpconf to abstract loading configuration and derpconf allows this.

Extensibility Section

LOADER

The loader is responsible for retrieving the source image that thumbor will work with. This configuration defines the module that thumbor will use for it. This must be a full namespace module (a.k.a. python has to be able to *import* it).

LOADER = 'thumbor.loaders.http_loader'

STORAGE

The storage is responsible for storing the source image bytes and related metadata (face-detection, encryption and such) so that we don’t keep loading it every time. This must be a full namespace module (a.k.a. python has to be able to *import* it).

STORAGE = 'thumbor.storages.file_storage'

MIXED_STORAGE_FILE_STORAGE

If you are using thumbor’s mixed storage (thumbor.storages.mixed_storage), this is where you specify the storage that will be used to store images. This must be a full namespace module (a.k.a. python has to be able to *import* it).

MIXED_STORAGE_FILE_STORAGE = 'thumbor.storages.file_storage'

MIXED_STORAGE_CRYPTO_STORAGE

If you are using thumbor’s mixed storage (thumbor.storages.mixed_storage), this is where you specify the storage that will be used to store cryptography information. This must be a full namespace module (a.k.a. python has to be able to *import* it).

MIXED_STORAGE_CRYPTO_STORAGE = 'thumbor.storages.file_storage'

MIXED_STORAGE_DETECTOR_STORAGE

If you are using thumbor’s mixed storage (thumbor.storages.mixed_storage), this is where you specify the storage that will be used to store facial and feature detection results. This must be a full namespace module (a.k.a. python has to be able to *import* it).

MIXED_STORAGE_DETECTOR_STORAGE = 'thumbor.storages.file_storage'

RESULT_STORAGE

The result storage is responsible for storing the resulting image with the specified parameters (think of it as a cache), so that we don’t keep processing it every time a request comes in. This must be a full namespace module (a.k.a. python has to be able to *import* it).

RESULT_STORAGE = 'thumbor.result_storages.file_storage'

ENGINE

The engine is responsible for transforming the image. This must be a full namespace module (a.k.a. python has to be able to *import* it).

Currently, thumbor ships with only the thumbor.engines.pil imaging engine. A few years ago we conducted a comparison between the engines and there was no clear winner. Given PIL was the engine we were using at the time, we decided to stick with it. Other open source engines exist and you can find more about them in the plug-in section of the docs.

ENGINE = 'thumbor.engines.pil'

URL_SIGNER

The url signer is responsible for validation and signing of requests to prevent url tampering, which could lead to denial of service (example: filling the result_storage by specifying a different size). This must be a full namespace module (a.k.a. python has to be able to *import* it).

URL_SIGNER = 'libthumbor.url_signers.base64_hmac_sha1'

Filters Section

In order to specify the filters that thumbor will use, you need a configuration key called FILTERS. This is a regular python list with the full names (names that python can import) of the filter modules you want to use.

i.e.:

FILTERS = [
    'thumbor.filters.brightness',
    'thumbor.filters.contrast',
    'thumbor.filters.rgb',
    'thumbor.filters.round_corner',
    'thumbor.filters.quality',
    'thumbor.filters.noise',
    'thumbor.filters.watermark',
]

Metadata Section

META_CALLBACK_NAME

If you want thumbor to use JSONP for image metadata instead of using JSON, just set this variable to the callback name you want.

META_CALLBACK_NAME = 'thumbor_callback'  # Or None for no callback

Face and Feature Detection Section

DETECTORS

This options specifies the detectors that should run the image to check for focal points.

i.e.:

 DETECTORS = [
   'thumbor.detectors.face_detector',
   'thumbor.detectors.feature_detector'
]

Cascade Files

This option specifies the cascade (XML) file paths to train openCV to find faces or other objects.

## The cascade file that opencv will use to detect faces.
FACE_DETECTOR_CASCADE_FILE = 'haarcascade_frontalface_alt.xml'

## The cascade file that opencv will use to detect glasses.
GLASSES_DETECTOR_CASCADE_FILE = 'haarcascade_eye_tree_eyeglasses.xml'

## The cascade file that opencv will use to detect profile faces.
PROFILE_DETECTOR_CASCADE_FILE = 'haarcascade_profileface.xml'

Imaging Section

ALLOWED_SOURCES

This configuration defines the source of the images that thumbor will load. This is only used in the HttpLoader (check the LOADER configuration above).

ALLOWED_SOURCES=['http://s.glbimg.com']

Another example with wildcards:

ALLOWED_SOURCES=['.+\.globo\.com', '.+\.glbimg\.com']

This is to get any images that are in *.globo.com or *.glbimg.com and it will fail with any other domains.

ACCESS_CONTROL_ALLOW_ORIGIN_HEADER

This allows to send the ACCESS_CONTROL_ALLOW_ORIGIN header. For example, if you want to tell the browser to allow code from any origin to access your thumbor resources:

ACCESS_CONTROL_ALLOW_ORIGIN_HEADER = '*'

If you want restrict access to a certain resource:

ACCESS_CONTROL_ALLOW_ORIGIN_HEADER = 'https://www.example.com'

Not set by default.

MAX_WIDTH and MAX_HEIGHT

These define the box that the resulting image for thumbor must fit-in. This means that no image that thumbor generates will have a width larger than MAX_WIDTH or height larger than MAX_HEIGHT. It defaults to 0, which means there is not limit. If the original image is larger than MAX_WIDTH x MAX_HEIGHT, it is proportionally resized to MAX_WIDTH x MAX_HEIGHT.

MAX_WIDTH = 1200
MAX_HEIGHT = 800

MIN_WIDTH and MIN_HEIGHT

These define the box that the resulting image for thumbor must fit-in. This means that no image that thumbor generates will have a width smaller than MIN_WIDTH or height smaller than MIN_HEIGHT. It defaults to 1. If the original image is smaller than MIN_WIDTH x MIN_HEIGHT, it is proportionally resized to MIN_WIDTH x MIN_HEIGHT.

MIN_WIDTH = 1
MIN_HEIGHT = 1

QUALITY

This option defines the quality that JPEG images will be generated with. It defaults to 80.

QUALITY = 90

MAX_AGE

This option defines the number of seconds that images should remain in the browser’s cache. It relates directly with the Expires and Cache-Control headers.

MAX_AGE = 24 * 60 * 60  # A day of caching

MAX_AGE_TEMP_IMAGE

When an image has some error in its detection or it has deferred queueing, it’s convenient to set a much lower expiration time for the image cache. This way the browser will request the proper image faster.

This option defines the number of seconds that images in this scenario should remain in the browser’s cache. It relates directly with the Expires and Cache-Control headers.

MAX_AGE_TEMP_IMAGE = 60  # A minute of caching

RESPECT_ORIENTATION

If this option is set to True, thumbor will reorient the image according to it’s EXIF Orientation tag (if one can be found). This options defaults to False.

The operations performed in the image are as follow (considering the value of the Orientation EXIF tag):

1. Nothing

2. Flips the image horizontally

3. Rotates the image 180 degrees

4. Flips the image vertically

5. Flips the image vertically and rotates 270 degrees

6. Rotates the image 270 degrees

7. Flips the image horizontally and rotates 270 degrees

8. Rotates the image 90 degrees

RESPECT_ORIENTATION = False

ALLOW_ANIMATED_GIFS

This option indicates whether animated gifs should be supported.

ALLOW_ANIMATED_GIFS = True

USE_GIFSICLE_ENGINE

This option indicates whether gifsicle should be used for all gif images, instead of the actual imaging engine. This defaults to False.

When using gifsicle thumbor will generate proper animated gifs, as well as static gifs with the smallest possible size.

USE_GIFSICLE_ENGINE = True

WARNING: When using gifsicle engine, filters will be skipped, except for cover() filter. thumbor will not do smart cropping as well.

AUTO_*

These configurations indicates that thumbor will try to automatically convert the image format to a lighter image format, according to this compression order: WEBP, AVIF, JPG, HEIF, PNG — from highest (WEBP) to lowest (PNG) priority.

AUTO_WEBP

This option indicates whether thumbor should send WebP images automatically if the request comes with an “Accept” header that specifies that the browser supports “image/webp”.

AUTO_WEBP = True

AUTO_AVIF

This option indicates whether thumbor should send Avif images automatically if the request comes with an “Accept” header that specifies that the browser supports “image/avif” and pillow-avif-plugin is enabled.

AUTO_AVIF = True

AUTO_PNG_TO_JPG

This option indicates whether thumbor should transform PNG images automatically to JPEG. If the image is a PNG without transparency and the numpy dependency is installed, thumbor will transform from png to jpeg. In the most of cases the image size will decrease.

WARNING: Depending on case, this is not a good deal. This transformation maybe causes distortions or the size of image can increase. Images with texts, for example, the result image maybe will be distorted. Dark images, for example, the size of result image maybe will be bigger. You have to evaluate the majority of your use cases to take a decision about the usage of this conf.

AUTO_PNG_TO_JPG = True

AUTO_JPG

This option indicates whether thumbor should send JPG images automatically if the request comes with an “Accept” header that specifies that the browser supports “/”, “image/jpg” or “image/jpeg”.

AUTO_JPG = True

AUTO_PNG

This option indicates whether thumbor should send PNG images automatically if the request comes with an “Accept” header that specifies that the browser supports “image/png”.

AUTO_PNG = True

AUTO_HEIF

This option indicates whether thumbor should send Heif images automatically if the request comes with an “Accept” header that specifies that the browser supports “image/heif” and pillow-heif is enabled.

AUTO_HEIF = True
