Microservice to resize images on the fly

Generating the URL

The URL should contain the path and options, like this: /{options}/{encoded path}

Example:

domain.com/photo/w100,h200,c/encodedimagepath.jpg

Full list of options:

R: resize 
C: crop
Q: quality
G: gravity   
B: background 
W: watermark
F: filter 
P: pixel density ratio

R : resize

R({fit mode}){size}

Fit mode: contain. Default. Resizes the image to fit within the width and height boundaries without cropping, distorting or altering the aspect ratio.

f - fill. Resizes the image to fit within the width and height boundaries without cropping or distorting the image, and the remaining space is filled with the background color.

c - crop. Resizes the image to fill the width and height boundaries and crops any excess image data.

C : crop

C{x}x{y}x{width}x{height} Creates an image whose sizes are exactly the ones specified. The resized image is obtained picking it from a rectangle of the same sizes from the center of the image.

G : Gravity

When resize (in crop mode) is applied, changing the gravity will define which part of the image is kept inside the crop area. The basic options are:

• ce — center (default mode);
• sm — smart. libvips detects the most "interesting" section of the image and considers it as the center of the resulting image.
