![]() Image3.getPixelWriter().setPixels(0, 0, width, height,Īs a raw image format, the PixelReader image is much larger than the original, so if you are storing these images in a database and are concerned about space then you should try storing the original file bytes instead. WritableImage image3 = new WritableImage(width, height) Pane.getChildren().add(view2) // Won't work Image image2 = new Image(new ByteArrayInputStream(pixelBytes)) ![]() Image.getPixelReader().getPixels(0, 0, width, height, InputStream in = new ByteArrayInputStream(fileBytes) īyte pixelBytes = new byte Using ByteArrayInputStream to create a JavaFX Image will only work using the original, unmodified image file bytes in the supported formats (bmp, jpg, gif, png).Īfter using PixelReader to read an Image, the byte array will contain raw image bytes that can only be written back to a WritableImage using the PixelWriter, which is why using ByteArrayInputStream produces an invalid image.īelow is a reproducible example using this image: // Original image bytesįile file = new File("F:/Downloads/duke.png") īyte fileBytes = Files.readAllBytes(file.toPath()) Moreover, I want to convert it to the byte array so that it can be written to an image file. As I've already mentioned clearly that I do not want to use converting it to BufferedImage using SwingFXUtils. I've tried the following: PixelReader pixelReader = image.getPixelReader() īyte buffer = new byte īut the file generated by writing the byte buffer is not a valid image.ĮDIT: The solutions given at How to get byte from javafx imageView cannot be applied to my question. So that I can directly write the bytes to a file. ![]() I need the opposite without converting it first to the BufferedImage (omFXImage(image,null)). image = new Image(new ByteArrayInputStream(bytes)) Save my name, email, and website in this browser for the next time I comment.We can create FX Image object by using byte bytes = - //valid image in bytes Your email address will not be published.
