> The "type" is a standard that defines which characters you can encode and which bars represent which character. The most used types are [code 128](https://en.wikipedia.org/wiki/Code_128) and [EAN/UPC](https://en.wikipedia.org/wiki/International_Article_Number). Not all characters can be encoded into each barcode type, and not all barcode scanners can read all types.

- First, encode the string you want the barcode of into a `Barcode` object with one of the barcode types.

- Then, use one of the renderers to render the image of the bars in the `Barcode` object.
