Hi all!! A library uses Code 128B <https://en.wikipedia.org/wiki/Code_128> for its material barcodes, with the great ByWater's Label Maker <https://github.com/bywatersolutions/koha-plugin-label-maker> plugin. For the SVG image generation, we were using barcode.tec-it.com <https://barcode.tec-it.com/barcode.ashx?data=>, but they start reducing their usage limits, so I look back to Koha capabilities. As we know, Koha doesn't support Code128B <https://github.com/Koha-Community/Koha/blob/main/svc/barcode#L92>. It seems the libbarcode-code128-perl <https://metacpan.org/release/Barcode-Code128> dependency package is used only for OPACVirtualCardBarcode, where is a viable option. I could generate PNG 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); $code->option("border", 0); $code->option("transparent_text", 1); $code->option("scale", 4); $code->option("font_align", "center"); $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. Before I file a bug and maybe trying with JsBarcode or even Jquery.. there is something I'm missing? Code 128 is not so un popular. Why is not supported? Also, a `format` parameter would be great, for a future SVG and stretch without loosing any quality. Regards, Pablo
