+ * All kinds of Text-elements can be added to a HTMLDocument. + * The Document signals all the listeners when an element has + * been added. + *

+ * Remark: + *

    + *
  1. Once a document is created you can add some meta information. + *
  2. You can also set the headers/footers. + *
  3. You have to open the document before you can write content. + *
  4. You can only write content (no more meta-formation!) once a document is + * opened. + *
  5. When you change the header/footer on a certain page, this will be + * effective starting on the next page. + *
  6. Ater closing the document, every listener (as well as its + * OutputStream) is closed too. + *
+ * Example:
+ * + * 
// creation of the document with a certain size and certain margins
+ * Document document = new Document(PageSize.A4, 50, 50, 50, 50);
+ *  try { // creation of the different writers HtmlWriter.getInstance(
+ * document , System.out); PdfWriter.getInstance(
+ * document , new FileOutputStream("text.pdf"));
+ *    // we add some meta information to the document
+ * document.addAuthor("Bruno Lowagie"); 
+ * document.addSubject("This is the result of a Test."); 
+ *  // we define a header and a footer HeaderFooter header = new
+ * HeaderFooter(new Phrase("This is a header."), false); HeaderFooter footer =
+ * new HeaderFooter(new Phrase("This is page "), new Phrase("."));
+ *    footer.setAlignment(Element.ALIGN_CENTER);
+ * document.setHeader(header); 
+ * document.setFooter(footer); // we open the document for
+ * writing document.open();  document.add(new
+ * Paragraph("Hello world")); } catch(DocumentException de) {
+ * System.err.println(de.getMessage()); } document.close();

+ * This implementation is not optimized for performance. It is intended + * as a reference implementation that closely follows the specification + * of the Bidirectional Algorithm in The Unicode Standard version 3.0. + *

+ * Input:
+ * There are two levels of input to the algorithm, since clients may prefer + * to supply some information from out-of-band sources rather than relying on + * the default behavior. + *

    + *
  1. unicode type array + *
  2. unicode type array, with externally supplied base line direction + *
+ *

Output:
+ * Output is separated into several stages as well, to better enable clients + * to evaluate various aspects of implementation conformance. + *

    + *
  1. levels array over entire paragraph + *
  2. reordering array over entire paragraph + *
  3. levels array over line + *
  4. reordering array over line + *
+ * Note that for conformance, algorithms are only required to generate correct + * reordering and character directionality (odd or even levels) over a line. + * Generating identical level arrays over a line is not required. Bidi + * explicit format codes (LRE, RLE, LRO, RLO, PDF) and BN can be assigned + * arbitrary levels and positions as long as the other text matches. + *

+ * As the algorithm is defined to operate on a single paragraph at a time, + * this implementation is written to handle single paragraphs. Thus + * rule P1 is presumed by this implementation-- the data provided to the + * implementation is assumed to be a single paragraph, and either contains no + * 'B' codes, or a single 'B' code at the end of the input. 'B' is allowed + * as input to illustrate how the algorithm assigns it a level. + *

+ * Also note that rules L3 and L4 depend on the rendering engine that uses + * the result of the bidi algorithm. This implementation assumes that the + * rendering engine expects combining marks in visual order (e.g. to the + * left of their base character in RTL runs) and that it adjust the glyphs + * used to render mirrored characters that are in RTL runs so that they + * render appropriately. + * + * @author Doug Felt + */ + +public final class BidiOrder { + private byte[] initialTypes; + private byte[] embeddings; // generated from processing format codes + private byte paragraphEmbeddingLevel = -1; // undefined + + private int textLength; // for convenience + private byte[] resultTypes; // for paragraph, not lines + private byte[] resultLevels; // for paragraph, not lines + + // The bidi types + + /** Left-to-right*/ + public static final byte L = 0; + + /** Left-to-Right Embedding */ + public static final byte LRE = 1; + + /** Left-to-Right Override */ + public static final byte LRO = 2; + + /** Right-to-Left */ + public static final byte R = 3; + + /** Right-to-Left Arabic */ + public static final byte AL = 4; + + /** Right-to-Left Embedding */ + public static final byte RLE = 5; + + /** Right-to-Left Override */ + public static final byte RLO = 6; + + /** Pop Directional Format */ + public static final byte PDF = 7; + + /** European Number */ + public static final byte EN = 8; + + /** European Number Separator */ + public static final byte ES = 9; + + /** European Number Terminator */ + public static final byte ET = 10; + + /** Arabic Number */ + public static final byte AN = 11; + + /** Common Number Separator */ + public static final byte CS = 12; + + /** Non-Spacing Mark */ + public static final byte NSM = 13; + + /** Boundary Neutral */ + public static final byte BN = 14; + + /** Paragraph Separator */ + public static final byte B = 15; + + /** Segment Separator */ + public static final byte S = 16; + + /** Whitespace */ + public static final byte WS = 17; + + /** Other Neutrals */ + public static final byte ON = 18; + + /** Minimum bidi type value. */ + public static final byte TYPE_MIN = 0; + + /** Maximum bidi type value. */ + public static final byte TYPE_MAX = 18; + + // + // Input + // + + /** + * Initialize using an array of direction types.

(CFF fonts may also contain multiple fonts; I do not + * know if this is allowed in an OT table). The PDF spec, however, only + * allow a CID font with an Identity-H or Identity-V encoding. Otherwise, + * you are limited to an 8-bit encoding. + * Adobe fonts come in both flavors. That is, the OTFs sometimes have + * a CID CFF inside (for Japanese fonts), and sometimes a Type1 CFF + * (virtually all the others, Latin/Greek/Cyrillic). So to easily use + * all the glyphs in the latter, without creating multiple 8-bit encoding, + * I wrote this class, whose main purpose is to convert a Type1 font inside + * a CFF container (which might include other fonts) into a CID CFF font + * that can be directly embeded in the PDF. + * + * Limitations of the current version: + * 1. It does not extract a single CID font from a CFF that contains that + * particular CID along with other fonts. The Adobe Japanese OTF's that + * I have only have one font in the CFF table, so these can be + * embeded in the PDF as is. + * 2. It does not yet subset fonts. + * 3. It may or may not work on CFF fonts that are not within OTF's. + * I didn't try that.

    Ternary Search Tree.

    + * + *

    A ternary search tree is a hibrid between a binary tree and + * a digital search tree (trie). Keys are limited to strings. + * A data value of type char is stored in each leaf node. + * It can be used as an index (or pointer) to the data. + * Branches that only contain one key are compressed to one node + * by storing a pointer to the trailer substring of the key. + * This class is intended to serve as base class or helper class + * to implement Dictionary collections or the like. Ternary trees + * have some nice properties as the following: the tree can be + * traversed in sorted order, partial matches (wildcard) can be + * implemented, retrieval of all keys within a given distance + * from the target, etc. The storage requirements are higher than + * a binary tree but a lot less than a trie. Performance is + * comparable with a hash table, sometimes it outperforms a hash + * function (most of the time can determine a miss faster than a hash).

    + * + *

    The main purpose of this java port is to serve as a base for + * implementing TeX's hyphenation algorithm (see The TeXBook, + * appendix H). Each language requires from 5000 to 15000 hyphenation + * patterns which will be keys in this tree. The strings patterns + * are usually small (from 2 to 5 characters), but each char in the + * tree is stored in a node. Thus memory usage is the main concern. + * We will sacrify 'elegance' to keep memory requirenments to the + * minimum. Using java's char type as pointer (yes, I know pointer + * it is a forbidden word in java) we can keep the size of the node + * to be just 8 bytes (3 pointers and the data char). This gives + * room for about 65000 nodes. In my tests the english patterns + * took 7694 nodes and the german patterns 10055 nodes, + * so I think we are safe.

    + * + *

    All said, this is a map with strings as keys and char as value. + * Pretty limited!. It can be extended to a general map by + * using the string representation of an object and using the + * char value as an index to an array that contains the object + * values.

    + * A RtfWriter can be added as a DocListener + * to a certain Document by getting an instance. + * Every Element added to the original Document + * will be written to the OutputStream of this RtfWriter. + *
