Help Using Help Reference Back 67 Description The File lineFeed attribute determines the way line feed characters are written. This can be one of the three values: macintosh, unix or windows (actually, only the first character is interpreted). Type String (one of: macintosh, unix, windows); read/write. File open() method File(path).open(mode, type, creator) Description The File open() method opens the file for subsequent read/write operations. The type and creator arguments are optional and Macintosh specific; they specify the file type and creator as two four-character strings. They are used if the file is newly created. On other platforms, they are ignored. When open() is used to open a file for read access, the method attempts to detect the encoding of the open file. It reads a few bytes at the current location and tries to detect the Byte Order Mark character 0xFFFE. If found, the current position is advanced behind the detected character and the encoding property is set to one of the strings UCS-2BE, UCS-2LE, UCS4-BE, UCS-4LE or UTF-8. If the marker character cannot be found, it checks for zero bytes at the current location and makes an assumption about one of the above formats (except for UTF-8). If everything fails, the encoding property is set to the system encoding. The method resolves any aliases to find the file. You should be careful if you try to open a file more than once. The operating system usually permits you to do so, but if you start writing to the file using two different File objects, you may destroy your data. The return value is true if the file has been opened successfully, false otherwise. Parameters mode type creator one of r, w or e: r (read) Opens for reading. If the file does not exist or cannot be found, the call fails. w (write) Opens an empty file for writing. If the file exists, its contents are destroyed. e (edit) Opens an existing file for reading and writing. The Macintosh file type; a four-byte character string; ignored on non-Macintosh operating systems. The Macintosh file creator; a four-byte character string; ignored on non-Macintosh operating systems. Returns Boolean. File openDialog() Class method File.openDialog(prompt, select) Description The File.openDialog class method presents the Open dialog box that is standard for the platform on which After Effects is running. This method overlaps somewhat with the easier to use fileGetDialog() global function. Using Help Back 67
