JavaFX create a new image from an existing one

In JavaFX u can create a new Image from a string(path), how would i go about creating a new Image from an existing javafx.scene.image.image?
as following:
Image image2 = new Image("my/res/flower.png", 100, 150, false, false);
But instead of the path an actual image object.
I want to change the size of the image.

There is typically no need to create a new Image instance in order to perform rescaling. The API allows you to view or draw scaled versions of an existing Image instance. For example, given
Image image = new Image("my/res/flower.png");
you can create an ImageView that displays a scaled version with
ImageView imageView = new ImageView(image);
imageView.setFitWidth(100);
imageView.setFitHeight(150);
or you can draw a scaled version to a canvas with
Canvas canvas = ... ;
GraphicsContext gc = canvas.getGraphicsContext2D();
gc.drawImage(image, 0, 0, image.getWidth(), image.getHeight(), 0, 0, 100, 150);

A late response, but since I ran into the same issue (I needed an Image to pass to setDragView() ), here is the solution I have implemented:
Image makeThumbnail(Image original) {
ImageView i = new ImageView(original);
i.setFitHeight(64); i.setFitWidth(64);
return i.snapshot(new SnapshotParameters(), new WritableImage(64, 64));
}

Add Translucent Image to JLayeredPane

So I'm making a stopmotion application - the live feed from my webcam is inside a JPanel (with setOpaque(false)) that is inside the top (10th) layer in a JLayeredPane - and basically, when I take a picture, I want to add it to one of the lower layers so that a trace of the previous pictures you've taken shows up on screen. Here's how I'm trying to do that now:
EDIT: this is my new code based off the answer below - this now does nothing, as opposed to just adding the opaque image as before - if I add this to a JPanel, though, and add the JPanel to the JLayeredPane, then all I get is gray
BufferedImage img2 = new BufferedImage(img.getWidth(), img.getHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics2D g = img2.createGraphics();
g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, .5f));
g.drawImage(img2, 0, 0, null);
g.dispose();
ImageIcon imgIcon = new ImageIcon(new ImageIcon(img2).getImage().getScaledInstance(img2.getWidth(), img2.getHeight(), Image.SCALE_SMOOTH));
JLabel showPic = new JLabel(imgIcon);
showPic.setSize(layers.getSize());
showPic.setBounds(layers.getX() + 18, layers.getY(), img2.getWidth(), img2.getHeight());
layers.add(showPic, new Integer(1)); //layers is my JLayeredPane
layers.repaint();
layers.revalidate();
img is the picture I've just captured from my webcam, and I'm trying to make it semi transparent, then add it to a JLabel. How can I make this work? Or is there a better way to do this?

I don't know if this will solve the problem but the image you are looking for is
BufferedImage img2 = new BufferedImage(img.getWidth(), img.getHeight(), BufferedImage.TYPE_INT_ARGB);
java.awt.Transparency.TRANSLUCENT has the value of 3 and corresponds to BufferedImage.TYPE_INT_ARGB_PRE which only god knows what it's doing.
With BufferedImage.TYPE_INT_ARGB you can create a transparent image and apply Composite etc
You also need to correct this
g.drawImage(img2, null, 0, 0);
to
g.drawImage(img2, 0, 0, null);

Heres how transparency works for me:
I have two images bim and bim2 and I draw one on top of the other:
BufferedImage bim=null, bim2=null;
try {
bim=ImageIO.read(new File("...."));
bim2=ImageIO.read(new File("...."));
}
catch (Exception ex) { System.err.println("error in bim "+ex); }
int wc=bim.getWidth(), hc=bim.getHeight();
BufferedImage img2 = new BufferedImage(bim.getWidth(), bim.getHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics2D g = img2.createGraphics();
g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, .5f));
g.drawImage(bim, 0, 0, null);
g.drawImage(bim2, 0, 0, wc, hc, null);
Then I can display it on a JPanel Jframe or whatever.
I can even create the Label:
JLabel showPic = new JLabel(new ImageIcon(img2));
JFrame f=new JFrame();
f.setSize(500, 500);
f.add(showPic);
f.setVisible(true);

Set Font type to Futura in Java

Every thing works fine except that it does not print Futura Font on the picture just a default looking font
BufferedImage image = ImageIO.read(new File("image.jpeg"));
Graphics g =image.getGraphics();
g.setFont(new Font("Futura", Font.PLAIN, 45));
g.drawString("Hello", 100, 440);
ImageIO.write(image, "png", new File("test.png"));

Maybe this can help :)

How to change font style of text on image in java?

I am creating image dynamically and writing on image, there are limited set of font style.I want to change it to some other style in "Kunstler Script".
here is my code:
BufferedImage image = new BufferedImage(imageWidth,
imageHeight,BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = image.createGraphics();
g2.clearRect(0, 0, imageWidth, imageHeight);
g2.drawImage(image, 0, 0, null);
g2.setFont(new Font(Font.SANS_SERIF, Font.BOLD, 65));
g2.setColor(Color.orange);
g2.drawString(" MY IMAGE", 350, 70);
g2.drawLine(350, 80, 1000, 80);
g2.dispose();
File out = new File("E:/" + IMAGE + "_1.png");
ImageIO.write(image, "png", out);
here i want to change the font style
g2.setFont(new Font(Font.SANS_SERIF, Font.BOLD, 65));
at the place of "SANS_SERIF" i want some another font like "Kunstler Script"
please anybody help me to FIX it.
Thank you.

Assuming Kuntsler Script is an available font, it's as simple as:
g2.setFont(new Font("Kunstler Script", Font.BOLD, 65));

How to draw char of Wingding.ttf font with Java Graphics.DrawString?

I am trying to draw characters from Wingding.ttf font with Java Graphics.DrawString. But resulting image contains only rectangle instead of char.
BufferedImage image = new BufferedImage(100, 100, BufferedImage.TYPE_4BYTE_ABGR);
Graphics graphics = image.getGraphics();
Font font = new Font("Wingdings", Font.PLAIN, 20);
graphics.setFont(font);
graphics.setColor(Color.BLACK);
graphics.drawString("\u00d8", 10, 10); // THREE-D TOP-LIGHTED RIGHTWARDS ARROWHEAD char
ImageIO.write(image, "PNG", new File(TEST_DATA_DIR + "bullet_char.png"));
How can I do this?

I dont think wingdings is one of the "standard" fonts
Font font = null;
try {
font=Font.createFont( Font.TRUETYPE_FONT,
new FileInputStream(new File("/pathto/WINGDINGS.TTF")) );
} catch(Exception e) {
System.out.println(e);
}
font=font.deriveFont(Font.PLAIN, 200);
graphics.setFont(font);
once you load the font (its always PLANE 1 pnt) you can the derive the style and size you want....

As similar questions has been answered here: Drawing exotic fonts in a java applet, you need to pass \uF0d8 instead of \u00d8.
graphics.drawString("\uF0d8", 10, 10);
