JavaFX. Displaying an image from byte[]
0
This is now solved!
The solution is in the code below
My initial question below
I need to display an Image from pixels received as an array of bytes-one byte per pixel- into a ImageView.
The image was originally in png format.
private WritableImage convertByteArrayToImage(byte pixels, int width,int height) {
int imageType= Integer.valueOf(expTime.getText());
int ints = new int[pixels.length];
for (int i = 0; i < pixels.length; i++) {
ints[i] = (int) pixels[i] & 0xff;
}
BufferedImage bImg
= new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY);
WritableRaster raster = (WritableRaster) bImg.getData();
raster.setPixels(0, 0, width, height, ints);
bImg.setData(raster);
return SwingFXUtils.toFXImage(bImg, null);
}
Thanks

How did the data get into the byte array to begin with? And what is the format of the data in the byte array? Hint, it is not png, because JavaFX understands png and if it were png, thenImage img = new Image(new ByteArrayInputStream(data));would not throw an exception.

Can you post the full stack trace of theImageStorageException?

Solved!! The solution is based on my code-2- (edited). It was a matter of changing the way the BufferedImage was created. Seen here: [link] stackoverflow.com/questions/10061029/…
