It is most - * useful for use with legacy data formats and legacy display technology - * (simple terminals). All operations are performed on Unicode characters.</p> - * - * <p>Text-based shaping means that some character code points in the text are - * replaced by others depending on the context. It transforms one kind of text - * into another. In comparison, modern displays for Arabic text select - * appropriate, context-dependent font glyphs for each text element, which means - * that they transform text into a glyph vector.</p> - * - * <p>Text transformations are necessary when modern display technology is not - * available or when text needs to be transformed to or from legacy formats that - * use "shaped" characters. Since the Arabic script is cursive, connecting - * adjacent letters to each other, computers select images for each letter based - * on the surrounding letters. This usually results in four images per Arabic - * letter: initial, middle, final, and isolated forms. In Unicode, on the other - * hand, letters are normally stored abstract, and a display system is expected - * to select the necessary glyphs. (This makes searching and other text - * processing easier because the same letter has only one code.) It is possible - * to mimic this with text transformations because there are characters in - * Unicode that are rendered as letters with a specific shape - * (or cursive connectivity). They were included for interoperability with - * legacy systems and codepages, and for unsophisticated display systems.</p> - * - * <p>A second kind of text transformations is supported for Arabic digits: - * For compatibility with legacy codepages that only include European digits, - * it is possible to replace one set of digits by another, changing the - * character code points. These operations can be performed for either - * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic - * digits (U+06f0...U+06f9).</p> - * - * <p>Some replacements may result in more or fewer characters (code points). - * By default, this means that the destination buffer may receive text with a - * length different from the source length. Some legacy systems rely on the - * length of the text to be constant. They expect extra spaces to be added - * or consumed either next to the affected character or at the end of the - * text.</p> - * - * <p>For details about the available operations, see the description of the - * <code>U_SHAPE_...</code> options.</p> - * - * @param source The input text. - * - * @param sourceLength The number of UChars in <code>source</code>. - * - * @param dest The destination buffer that will receive the results of the - * requested operations. It may be <code>NULL</code> only if - * <code>destSize</code> is 0. The source and destination must not - * overlap. - * - * @param destSize The size (capacity) of the destination buffer in UChars. - * If <code>destSize</code> is 0, then no output is produced, - * but the necessary buffer size is returned ("preflighting"). - * - * @param options This is a 32-bit set of flags that specify the operations - * that are performed on the input text. If no error occurs, - * then the result will always be written to the destination - * buffer. - * - * @param pErrorCode must be a valid pointer to an error code value, - * which must not indicate a failure before the function call. - * - * @return The number of UChars written to the destination buffer. - * If an error occurred, then no output was written, or it may be - * incomplete. If <code>U_BUFFER_OVERFLOW_ERROR</code> is set, then - * the return value indicates the necessary destination buffer size. - * @stable ICU 2.0 - */ -U_STABLE int32_t U_EXPORT2 -u_shapeArabic(const UChar *source, int32_t sourceLength, - UChar *dest, int32_t destSize, - uint32_t options, - UErrorCode *pErrorCode); - -/** - * Memory option: allow the result to have a different length than the source. - * Affects: LamAlef options - * @stable ICU 2.0 - */ -#define U_SHAPE_LENGTH_GROW_SHRINK 0 - -/** - * Memory option: allow the result to have a different length than the source. - * Affects: LamAlef options - * This option is an alias to U_SHAPE_LENGTH_GROW_SHRINK - * @stable ICU 4.2 - */ -#define U_SHAPE_LAMALEF_RESIZE 0 - -/** - * Memory option: the result must have the same length as the source. - * If more room is necessary, then try to consume spaces next to modified characters. - * @stable ICU 2.0 - */ -#define U_SHAPE_LENGTH_FIXED_SPACES_NEAR 1 - -/** - * Memory option: the result must have the same length as the source. - * If more room is necessary, then try to consume spaces next to modified characters. - * Affects: LamAlef options - * This option is an alias to U_SHAPE_LENGTH_FIXED_SPACES_NEAR - * @stable ICU 4.2 - */ -#define U_SHAPE_LAMALEF_NEAR 1 - -/** - * Memory option: the result must have the same length as the source. - * If more room is necessary, then try to consume spaces at the end of the text. - * @stable ICU 2.0 - */ -#define U_SHAPE_LENGTH_FIXED_SPACES_AT_END 2 - -/** - * Memory option: the result must have the same length as the source. - * If more room is necessary, then try to consume spaces at the end of the text. - * Affects: LamAlef options - * This option is an alias to U_SHAPE_LENGTH_FIXED_SPACES_AT_END - * @stable ICU 4.2 - */ -#define U_SHAPE_LAMALEF_END 2 - -/** - * Memory option: the result must have the same length as the source. - * If more room is necessary, then try to consume spaces at the beginning of the text. - * @stable ICU 2.0 - */ -#define U_SHAPE_LENGTH_FIXED_SPACES_AT_BEGINNING 3 - -/** - * Memory option: the result must have the same length as the source. - * If more room is necessary, then try to consume spaces at the beginning of the text. - * Affects: LamAlef options - * This option is an alias to U_SHAPE_LENGTH_FIXED_SPACES_AT_BEGINNING - * @stable ICU 4.2 - */ -#define U_SHAPE_LAMALEF_BEGIN 3 - - -/** - * Memory option: the result must have the same length as the source. - * Shaping Mode: For each LAMALEF character found, expand LAMALEF using space at end. - * If there is no space at end, use spaces at beginning of the buffer.
