Hi Eduardo, thanks in advance. My question is, can we insert an external image in a report generated with YARG ?

Thanks,

Hello @fdomenechm,

You can use a barcode in a report, you need to create a report with an image format for the entity field.

Docs: Report Parameters and Field Formatters :: Jmix Documentation

I created a demo project that generates a barcode and saves it in entity.

BarcodeEntityEdit:

@Autowired
    private FileStorage fileStorage;

    @Subscribe(target = Target.DATA_CONTEXT)
    public void onPreCommit(final DataContext.PreCommitEvent event) throws Exception {
        BarcodeEntity barcodeEntity = getEditedEntity();

        InputStream inputStream = generateEAN13File(barcodeEntity.getBarcodeText());

        FileRef fileRef = fileStorage.saveStream("barcode.jpg", inputStream);
        barcodeEntity.setBarcode(fileRef);
    }


    public InputStream generateEAN13File(String barcodeText) throws Exception {
        Code128Writer barcodeWriter = new Code128Writer();
        BitMatrix bitMatrix = barcodeWriter.encode(barcodeText, BarcodeFormat.CODE_128, 300, 150);

        BufferedImage bufferedImage = MatrixToImageWriter.toBufferedImage(bitMatrix);

        ByteArrayOutputStream os = new ByteArrayOutputStream();
        ImageIO.write(bufferedImage, "jpeg", os);
        return new ByteArrayInputStream(os.toByteArray());
    }
