  • Generates URLs urls
  • Support for signing urls
  • URL's Factories with predefined params

Table of Contents

Requirements

  • python >= 3.7

Installation

imgproxy should be installed using pip:

$ pip install imgproxy

Usage

 from imgproxy import ImgProxy
 # Create ImgProxy object with required params
 img_url = ImgProxy('https://picsum.photos/1000', proxy_host='https://imgproxy.com', width=800, height=400)
 # Convert the obj to string to get imgproxy URL
 cover: str = str(img_url)
 # or just call it to get imgproxy URL
 cover: str = img_url()
 assert cover == 'https://imgproxy.com/insecure/g:ce/rs:auto:800:400:0/aHR0cHM6Ly9waWNzdW0ucGhvdG9zLzEwMDA'
 # Call the object with different params to customize the url
 cover_small: str = img_url(width=400, height=200, resizing_type='fill')
 assert cover_small == 'https://imgproxy.com/insecure/g:ce/rs:fill:400:200:0/aHR0cHM6Ly9waWNzdW0ucGhvdG9zLzEwMDA'
 # Call it with advanced params to get an URL
 cover_with_border = img_url('pd:10:10:10:10', 'bg:F00')
 assert cover_with_border == 'https://imgproxy.com/insecure/pd:10:10:10:10/bg:F00/g:ce/rs:auto:0:0:0/aHR0cHM6Ly9waWNzdW0ucGhvdG9zLzEwMDA'

Options

Basic options (default values):

  • width: int = 0 - images width
  • height: int = 0 - images height
  • gravity: str = 'ce' - images gravity
  • enlarge: bool = False - enlarge an image
  • extension: str = '' - images extension
  • resizing_type: str = 'auto' - resizing type
 from imgproxy import ImgProxy
 img_url = ImgProxy('https://picsum.photos/1000', proxy_host='https://imgproxy.com')
 thumbmail = img_url(width=100, height=100, gravity='no', extension='jpg', enlarge=True, resizing_type='fit')

Any other options are also supported when you call an imageproxy instance:

 from imgproxy import ImgProxy
 img_url = ImgProxy('https://picsum.photos/1000', proxy_host='https://imgproxy.com')
 # Get rotated and blured image
 blured_rotated = img_url('blur:0.5', 'rotate:30')

Signed URLs

Imgproxy allows you to sign your URLs with key and salt, so an attacker won’t be able to cause a denial-of-service attack by requesting multiple different image resizes.

 from imgproxy import ImgProxy
 url = ImgProxy('https://picsum.photos/1000', proxy_host='https://imgproxy.com', key="aa396160c50ea766910eab53", salt="b3fb8f215827bda5d0e7313d")
 assert str(url) == 'https://imgproxy.com/FrH21u_5bXmv-OJ0APMayxZ0F3982xx437gCpqcQ0BM/g:ce/rs:auto:600:0:0/aHR0cHM6Ly9waWNzdW0ucGhvdG9zLzEwMDA'

If you need a random key/salt pair real fast, you can quickly generate it using, for example, the following snippet:

 echo $(xxd -g 2 -l 64 -p /dev/random | tr -d '\n')

Image factories

Usually imgproxy host and signature params are common for a project. The library supports a method to generate a factory with predefined params:

 from imgproxy import ImgProxy
 img_factory = ImgProxy.factory(proxy_host='https://imgproxy.com', key="aa396160c50ea766910eab53", salt="b3fb8f215827bda5d0e7313d")
 # ...
 # Generate image URL
 url = img_factory('https://picsum.photos/1000', width=600)
 assert str(url) == 'https://imgproxy.com/qcKAFfBJwpiKZ6xt-NT6GXGOGizkeq4sgyfoQ4h-080/g:ce/rs:auto:600:0:0/aHR0cHM6Ly9waWNzdW0ucGhvdG9zLzEwMDA'

Users able to predifine any basic params:

 thumbnail_factory = ImgProxy.factory(proxy_host='https://imgproxy.com', width=300, height=200)
 preview_factory = ImgProxy.factory(proxy_host='https://imgproxy.com', width=500, resizing_type='fit')
 # and etc

Advanced params are also supported:

 thumbnail_factory = ImgProxy.factory('bg:F00', 'pd:10:10:10:10', proxy_host='https://imgproxy.com', width=300, height=200)
