ImgProxy -- Python library to build ImgProxy URLs
- python >= 3.7
imgproxy should be installed using pip:
$ pip install imgproxy
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'
Basic options (default values):
width: int = 0
- images widthheight: int = 0
- images heightgravity: str = 'ce'
- images gravityenlarge: bool = False
- enlarge an imageextension: str = ''
- images extensionresizing_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')
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')
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)
