Java GlyphLayout.get方法代码示例

import sun.font.GlyphLayout; //导入方法依赖的package包/类
/**
 * 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
