Get Text Extent

\i C ? T string::text

Parameter	Type	Range	Description
text	string	ASCII chars (0x01 .. 0xFF)	text string to measure

Returns the extent of a text string when drawn with the current font.

• To terminate a string, a NULL character (\0) has to be placed.
• 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 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).

Response:

[ACK] word::height word::width [ACK]

Parameter	Type	Range	Description
height	word	0 ... display width - 1	height of the text string
width	word	0 ... display height - 1	width of the text string

Example

\iC?THello World!\0

Response Example

[ACK][00][51][00][10][ACK]

This response means that the text "Hello World!" will occupy a space of width = 81 (0x51) pixels, and height = 16 (0x10) pixels with the selected font.
