How to get byte[] from javafx imageView?

Question

How do i get byte[] from javafx image/imageview class? I want to store my image as a Blob into my database.This is the method that i use for it ``` public PreparedStatement prepareQuery(HSQLDBConnector connector) { try { Blob logoBlob = connector.connection.createBlob(); logoBlob.setBytes(0,logo.getImage());//stuck here for (int i = 0, a = 1; i < data.length; i++, a++) { connector.prepStatCreateProfile.setString(a, data[i]); } //store LOB connector.prepStatCreateProfile.setBlob(11, logoBlob); } catch (SQLException ex) { ex.printStackTrace(); } return connector.prepStatCreateProfile; } ``` Is there a way to convert from my current object (imageview),image) into byte[]?, or shoud i start to think about using other class for my image/ alternatively point to the location with reference and work with paths/urls?

Accepted Answer

try this one:

```
BufferedImage bImage = SwingFXUtils.fromFXImage(logo.getImage(), null);
ByteArrayOutputStream s = new ByteArrayOutputStream();
ImageIO.write(bImage, "png", s);
byte[] res  = s.toByteArray();
s.close(); //especially if you are using a different output stream.
```

should work depending on the logo class

you need to specify a format while writing and reading, and as far as I remember bmp is not supported so you will end up with a png byte array on the database
