Examples

python:

Python dpid.py "myImage.jpg" 

Golang:

dpid "myImage.jpg"              // downscales using default values
dpid "myImage.jpg" 256          // downscales to 256px width, keeping aspect ratio
dpid "myImage.jpg" 0 256        // downscales to 256px height, keeping aspect ratio
dpid "myImage.jpg" 128 0 0.5    // downscales to 128px width, keeping aspect ratio, using lamdba=0.5
dpid "myImage.jpg" 128 128      // downscales to 128x128px, ignoring aspect ratio

org 200x300	dpid lamdba=0.5	dpid lamdba=0.8
