Example 46 with TextLayout

use of java.awt.font.TextLayout in project jdk8u_jdk by JetBrains.

the class SunGraphics2D method drawString.

Example 47 with TextLayout

use of java.awt.font.TextLayout in project jdk8u_jdk by JetBrains.

the class Font method getStringBounds.

/**
     * Returns the logical bounds of the specified array of characters
     * in the specified <code>FontRenderContext</code>.  The logical
     * bounds contains the origin, ascent, advance, and height, which
     * includes the leading.  The logical bounds does not always enclose
     * all the text.  For example, in some languages and in some fonts,
     * accent marks can be positioned above the ascent or below the
     * descent.  To obtain a visual bounding box, which encloses all the
     * text, use the {@link TextLayout#getBounds() getBounds} method of
     * <code>TextLayout</code>.
     * <p>Note: The returned bounds is in baseline-relative coordinates
     * (see {@link java.awt.Font class notes}).
     * @param chars an array of characters
     * @param beginIndex the initial offset in the array of
     * characters
     * @param limit the end offset in the array of characters
     * @param frc the specified <code>FontRenderContext</code>
     * @return a <code>Rectangle2D</code> that is the bounding box of the
     * specified array of characters in the specified
     * <code>FontRenderContext</code>.
     * @throws IndexOutOfBoundsException if <code>beginIndex</code> is
     *         less than zero, or <code>limit</code> is greater than the
     *         length of <code>chars</code>, or <code>beginIndex</code>
     *         is greater than <code>limit</code>.
