## Description

This script supports both standard and extended Code 39 barcodes. The extended mode gives access to the full ASCII range (from 0 to 127). The script also gives the possibility to add a checksum.
`Code39(float x, float y, string code [, boolean ext [, boolean cks [, float w [, float h [, boolean wide]]]]])`
`x`: abscissa
`y`: ordinate
`code`: barcode value
`ext`: indicates if extended mode must be used (`true` by default)
`cks`: indicates if a checksum must be appended (`false` by default)
`w`: width of a narrow bar (`0.4` by default)
