How to get an image from database into < Image> in itext7?

In my invoiceGenerator i need to get an Image in the invoice that's stored in the postgres db as a byte[]

since i changed this image input from a local path hardcoded in method to an entity ImageDataFile in the database i have problems with itext7 recognising the file.

 try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
            PdfWriter writer = new PdfWriter(outputStream);

            PdfDocument pdfDocument = new PdfDocument(writer);
            pdfDocument.setDefaultPageSize(PageSize.A4);
            Document document = new Document(pdfDocument);

            float twocol1 = 280f;
            float[] twocolwidth1 = {twocol1, twocol1};
            float twocol = 200f;
            float[] twoColumnWidth = {twocol, twocol};


            ImageDataFile imageDataFileTopPage = imageRepos.findByName("goldencarrotImagekleinste.jpg")
                                .orElseThrow(() -> new ResourceNotFoundException("image                       not found")); 

            ImageData imageTopPageData = ImageDataFactory.create(imageDataFileTopPage.getImageData());

            Image imageTopPage = new Image(imageTopPageData);

as a byte[] variable it also didn't work because the imageDataFactory.create from itext7 doesnt recognise the file.

Solution

uhhh ohh my fault stupid, the first plan works now because i forgot the "!" sign in the while loop imageUtils.decompress. that declares why the byte[] wasn't recognised it was compressed....``

byte[] imageTopPageBytes = imageService.getImage("goldencarrotImagekleinste.jpg");
        ImageData imageTopPageData = ImageDataFactory.create(imageTopPageBytes);
        Image imageTopPage = new Image(imageTopPageData);


ImageService{

    public byte[] getImage(String name){

     ImageDataFile imageData = imageRepos.findByName(name).orElseThrow(() ->
                new ResourceNotFoundException("Image not found"));

     return ImageUtil.decompressImage(imageData.getImageData());
    }
}




ImageUtils{

    public static byte[] decompressImage(byte[] data) {
        Inflater inflater = new Inflater();
        inflater.setInput(data);

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream(data.length);

        byte[] tmp = new byte[4 * 1024];
        try {
            while (inflater.finished()) {   // <-- must be (!inflater.fisished())
                int count = inflater.inflate(tmp);
                outputStream.write(tmp, 0, count);
            }
            outputStream.close();
        } catch (DataFormatException | IOException e) {
            throw new RuntimeException(e);
        }
        return outputStream.toByteArray();
    }

beginnersmistake haha forgive me guys any thanks
