Reordering page formatted output

Page formatted bidirectional text displayed on the screen or as printed output is normally displayed in visual order. Some output devices reorder the text automatically, which means the output from the StreamServer must be in logical order when it is sent to such a device. The table below shows how to order the output from the StreamServer when using different types of drivers.

Driver	Output from the StreamServer
PCL drivers	Visual order.
Postscript drivers	Visual order.
GIF, BMP, etc.	Visual order.
RTF	Logical order.
PDF	Visual order.
Windows driver	Logical order.

Visually ordered page formatted Arabic text is in addition shaped – the glyphs for the letters are cursively joined, lam-alif ligatures are formed, and mirror characters (e.g. parentheses and brackets) are mirrored. Contextual shaping must therefore be performed on the text in order to create the correct sequences of glyphs. Shaping is automatically performed if you enable reordering of page formatted output. This functionality is restricted to be without vowel marks.

Note:

Visually ordered Arabic PCL output must be UTF-8 encoded.

To reorder the output per output connector

1	Activate the generic layer in the Platform view.

2	In the Platform view, double-click the output connector. The Output Connector Settings dialog box opens.

3	Click the Code page icon and select Reorder BiDi output in visual order.

To reorder the output from mirrored PageOUT layouts

If you mirror PageOUT output, reordering is enabled automatically. See the PageOUT documentation for information on how to mirror page layouts.
