As we know, Koha doesn't yet support Code128B. It seems the libbarcode-code128-perl dependency package is used only for OPACVirtualCardBarcode, where is an option. I could generate PNG (sadly no SVG) barcodes by naively tweaking `svc/barcode`: use Barcode::Code128; my %type_mapping = ( Code128b => 1, ); eval { if ( $type eq "Code128b") { my $code = new Barcode::Code128; $code->option("height", $height); $code->option("show_text", !$notext); $image = $code->png($barcode); } }; And ./cgi-bin/koha/svc/barcode?barcode=3721M&type=Code128b, but for some reason it fails (error 500) with some barcodes.
