This should work:
File file = new File("img.png");
System.out.println("Expecting to find file from " + file.getAbsolutePath());
Image image = new Image(new StreamResource("img.png", () -> {
try {
return new FileInputStream(file);
} catch (FileNotFoundException e) {
// file not found
e.printStackTrace();
}
return null;
}), "alt text");
Instead of a FileInputStream, you can use any other type of InputStream as well, like a ByteArrayInputStream
.

I’m still a bit slow with the functional interface.
Thank you very much!
The same without the lambda would be like this:
Image image = new Image(new StreamResource("img.png", new InputStreamFactory() {
@Override
public InputStream createInputStream() {
try {
return new FileInputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
return null;
}
}), "alt text");
