Examples with GlyphLayout sun.font.GlyphLayout used on opensource projects

Example 1 with GlyphLayout

use of sun.font.GlyphLayout in project jdk8u_jdk by JetBrains.

the class Font method layoutGlyphVector.

/**
     * Returns a new <code>GlyphVector</code> object, performing full
     * layout of the text if possible.  Full layout is required for
     * complex text, such as Arabic or Hindi.  Support for different
     * scripts depends on the font and implementation.
     * <p>
     * Layout requires bidi analysis, as performed by
     * <code>Bidi</code>, and should only be performed on text that
     * has a uniform direction.  The direction is indicated in the
     * flags parameter,by using LAYOUT_RIGHT_TO_LEFT to indicate a
     * right-to-left (Arabic and Hebrew) run direction, or
     * LAYOUT_LEFT_TO_RIGHT to indicate a left-to-right (English)
     * run direction.
     * <p>
     * In addition, some operations, such as Arabic shaping, require
     * context, so that the characters at the start and limit can have
     * the proper shapes.  Sometimes the data in the buffer outside
     * the provided range does not have valid data.  The values
     * LAYOUT_NO_START_CONTEXT and LAYOUT_NO_LIMIT_CONTEXT can be
     * added to the flags parameter to indicate that the text before
     * start, or after limit, respectively, should not be examined
     * for context.
     * <p>
     * All other values for the flags parameter are reserved.
     *
     * @param frc the specified <code>FontRenderContext</code>
     * @param text the text to layout
     * @param start the start of the text to use for the <code>GlyphVector</code>
     * @param limit the limit of the text to use for the <code>GlyphVector</code>
     * @param flags control flags as described above
     * @return a new <code>GlyphVector</code> representing the text between
     * start and limit, with glyphs chosen and positioned so as to best represent
     * the text
     * @throws ArrayIndexOutOfBoundsException if start or limit is
     * out of bounds
