Looking for a small 1d barcode generator

So using g as a global var is fine, that's what I do at the moment.

I'd say passing it in as an argument is more flexible...

require("my_lib").drawBarCode(g, myData);

Then you have the option of drawing offscreen if you need.

like this?

I'd suggest: map = atob("DSdyGTNmExtsPSFCIx1cMTlOLwVQOxFENw­lICxd0") then map.charCodeAt(index). You could use E.toUint8Array to avoid the charCodeAt but for smaller arrays like this, I guess charCodeAt is more efficient.
