How to generate kr-code from the console

As in all npm projects you have to type npm install - just reminder!

Install some stuff. I don't know what does it do, but you can't perform the next step without it:

brew install pkg-config cairo libpng jpeg giflib

Install canvas dependency:

npm install canvas

Now you can generate a krCode from the command line. It can be invoked with up to 4 parameters

• type
• value
• width in pixels
• rotation (0-3) 0=horizontal, 1=90 degree clockwise rotated ...

for example:

./generate-kr-code 3 10001 500 > kr-code.png

In case of trouble - ask the guy with the longest beard in the lambda team.
