Re: Fractional Metrics
I'm sorry if this is redundant, but does this mean there is no way to find out the size (length height) of a String as it will appear on the screen? What about the size of a String as it will be printed?

Re: Fractional Metrics
I have a couple of solutions for this right now, but neither are optimal: 1. GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice(),getDefaultConfiguration() .createCompatibleImage(1, 1).createGraphics().getFontMetrics(font).stringWidth(string) 2. new javafx.scene.text.Text().setFont(font).setText(string).prefWidth(-1) // Some poetic license here jeff On Apr 4, 2014, at 8:41 AM, ngalarn...@abinitio.com wrote: I'm sorry if this is redundant, but does this mean there is no way to find out the size (length height) of a String as it will appear on the screen?

Re: Fractional Metrics
If you don't mind using internal APIs then: TextLayoutFactory factory = Toolkit.getToolkit().getTextLayoutFactory(); TextLayout layout = factory.createLayout(); layout.setContent(BlaBla, Font.getDefault().impl_getNativeFont()); BaseBounds b = layout.getBounds(); I find it strange the canvas does not have an API to calculate the boudsn of a string.

Fractional Metrics
Is there a way to turn off FractionalMetrics in Canvas.fillText() or Text? Also, does text rendering perform kerning, and if so, can I disable that? What I really need is to know the x position (or advance) of each character in a rendered string. jeff
