>About barcodes generation, why don't use Artefact directly ? If you look at the implementation you will see that barcode generation is mostly about implementing the correct encoding (to get a string with 0s and 1s)
With this one can easily draw the lines on a form, a morph/canvas or directly in PDF. An easy way now is by using a form, see "BarcodeEAN13 example asForm" and then display this form in PDF via Artefact or use "asMorph openInWorld" Bye T.
