unreachable code

[calumsult]

In the scanImage function in the decoder there's this bit:

const result = processPixel.call(this, x, line); if (result === false) { return; }

...but processPixel is defined as returning void, hence the if statement will never evaluate to true. Any idea what was intended with that code? I can submit a pr and fix it, but just glancing at it I'm not sure what the intent was. Thanks!

it's been awhile since I've looked at this code. def seems like it could be removed. feel free to make a PR!
