Function Reference

Page 815 of 821

\TL[int]

The tag changes the current tabulator length. The value must be in the range 1 to 255. See

also SetTabLen().

\TR[float]

The tag changes the current text rise. Text rise can be used to create superscript or subscript

text parts inside a text block. The value must be in the range -1000 to 1000 units.

\TS[float]

The tag changes the current horizontal text scaling. The value must be greater zero. See also

SetTextScaling().

Special characters

The following list defines which characters can be used to insert new lines, tabulators and so on.

Character code (Hex)

Description

0x10 or 0x13 or

New line or end-of-line character code. The combination of a carriage return plus

0x13 + 0x10

a line feed will be treaded as single end-of-line character.

0x09

A tabulator is emulated by inserting a variable count of space characters. The

number of characters can be adjusted inside the text with the command tag

\TL[] or outside with the property SetTabLen().

The function supports also specific Unicode characters which are used to control the bidirectional

algorithm. The bidirectional formatting codes are also supported by all other text functions.

Character code (Hex)

Description

0x202A

LRE Left-to-Right Embedding (treat the following text as embedded left-to-right)

0x202B

RLE Right-to-Left Embedding (treat the following text as embedded right-to-left)

0x202C

PDF Pop Directional Format (restore the bidirectional state to what it was before

the last LRE, RLE, LRO or RLO)

0x202D

LRO Left-to-Right Override (force the following characters to be treated as

strong left-to-right characters)

0x202E

RLO Right-to-Left Override (force the following characters to be treated as

strong right-to-left characters)

0x200E

LRM Left-to-Right Mark (left-to-right zero-width character)

0x200F

RLM Right-to-Left Mark (right-to-left zero-width character)

0x200C

Zero width non-joiner

0x200D

Zero width joiner

The bidirectional code pages 1255 and 1256 support the character codes 0x200E and 0x200F only (the

mapped codes are 253 and 254).

Note that the Unicode character codes are supported by the Unicode version of the function only.
