A font is a GX or AAT font if it contains a 'mort' table. See Apple's 0N/A * Information about 'mort' tables is in the chapter titled "Font Files." 0N/A * This is the main constructor. It constructs an instance of GXLayoutEngine for 0N/A * a particular font, script and language. It takes the 'mort' table as a parameter since 0N/A * LayoutEngine::layoutEngineFactory has to read the 'mort' table to know that it has a 0N/A * Note: GX and AAT fonts don't contain any script and language specific tables, so 0N/A * the script and language are ignored. 0N/A * @param fontInstance - the font 0N/A * @param scriptCode - the script 0N/A * @param langaugeCode - the language 0N/A * @param morphTable - the 'mort' table 3171N/A * @param success - set to an error code if the operation fails 0N/A * @see LayoutEngine::layoutEngineFactory 0N/A * The destructor, virtual for correct polymorphic invocation. 1693N/A * ICU "poor man's RTTI", returns a UClassID for the actual class. 1693N/A * ICU "poor man's RTTI", returns a UClassID for this class. 0N/A * The address of the 'mort' table 0N/A * This method does GX layout using the font's 'mort' table. It converts the 0N/A * input character codes to glyph indices using mapCharsToGlyphs, and then 0N/A * applies the 'mort' table. 0N/A * @param chars - the input character context 0N/A * @param offset - the index of the first character to process 0N/A * @param count - the number of characters to process 0N/A * @param max - the number of characters in the input context 1693N/A * @param rightToLeft - <code>TRUE</code> if the text is in a right to left directional run 1693N/A * @param glyphStorage - the glyph storage object. The glyph and char index arrays will be set. 0N/A * Output parameters: 0N/A * @param success - set to an error code if the operation fails 0N/A * @return the number of glyphs in the glyph index array 0N/A * This method adjusts the glyph positions using the font's 0N/A * 'kern', 'trak', 'bsln', 'opbd' and 'just' tables. 1693N/A * @param glyphStorage - the object holding the glyph storage. The positions will be updated as needed. 0N/A * Output parameters: 0N/A * @param success - set to an error code if the operation fails
