This plug-in utilizes the Google Charts API. You can view the various ECL settings here .

Essentially, the ECL code consists of two components: (1) the error correction level (L, M, Q, or H), and (2) the white border row/column width (1 – 40 rows, not pixels).

If omitted, the URL defaults to the current page/post url. You can also use any valid url or text (within the character limitation of the selected ECL attribute value).

When using an email address , a standard format is expected. For example [email protected] should be implemented as mailto:[email protected] .

Telephone numbers also have a standardized format. For example, 212-555-1212 should be implemented as tel:+12125551212 .

An SMS link is encoded in a fashion similar to an email address. For example, a link to the number 12345 should be implemented as sms:12345 .
