How to get FontMetrics without use Graphics ? I want to get FontMetrics in constructor, now I do this way:
BufferedImage bi = new BufferedImage(5, 5, BufferedImage.TYPE_INT_RGB); FontMetrics fm = bi.getGraphics().getFontMetrics(font); int width = fm.stringWidth(pattern); int height = fm.getHeight();

The FontMetrics class defines a font metrics object, which encapsulates information about the rendering of a particular font on a particular screen.
setFont(Font f) Set the Font of this object. Constructors in java.awt with parameters of type Font. Constructor and Description.
Font metrics are measurements of text rendered by a Font object such as the height of a line of text in the font. The most common way to measure text is to use a FontMetrics instance which encapsulates this metrics information.

No you do not necessarily need to get/use the graphics object:
Font font = new Font("Helvetica",Font.PLAIN,12); Canvas c = new Canvas(); FontMetrics fm = c.getFontMetrics(font); If you would now call c.getGraphics() it would return null. The canvas solution on the other hand will also work in headless mode.

Hmm... It is quite logical that you need graphics to get FontMetrics. Font height, width etc. can differ on various displays.
If you have some Component, you can use it for getting FontMetrics:
component.getFontMetrics(font); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
