Get Text Message Extent

\i C ? t word::message_index

Parameter	Type	Range	Description
message_index	byte	0 ... max. message_index	index of the message stored in the iLCD

\i C ? t by_name::message_name

Parameter	Type	Range	Description
message_name	by_name	ASCII chars (0x01 .. 0xFF)	0-terminated message name

Returns the extent of a text message (stored in the iLCD via iLCD Manager XE) when drawn with the current font.

• If the message with the corresponding message_index or message_name is not available, a [NACK] is returned.
• When addressing by index, the message offset (see Set Message Offset) is taken into account.
• When addressing by name, the message prefix (refer to Set Message Name Prefix) and suffix (refer to Set Message Name Suffix) are taken into account.
• Any control characters like carriage returns and ANSI sequences are interpreted correctly if ANSI mode is enabled.
• Characters not defined in the current font table are calculated as full width spaces and this is how they are shown on the display.
• If you use a symbol font (refer to Set Symbol Font) no horizontal or vertical spaces between the characters will be displayed, and the this command calculates its values accordingly.
• If text alignment is on (see Set Text Alignment), the reported height and width values correspond to the setting of the alignment. However, the current cursor position is not taken into account (that means no correction of the right and bottom margin will be made in this case).
