ff_type: ff_text

FF text features hold text information. Either a single 2D position or a 2D line may be associated with the text feature that may hold several text strings in list attributes.

Text features may have the following special attributes associated with them:

Attribute Name	Description
ff_text_width	The width of the text string Range: Any real number
thojd	The height of the text If >0, the height is in 1/100mm. If <0, the height is based on a height code. The height code is converted to height using a separate table when plotting is done. Range: Integer
ff_text_height	When reading, if thojd > 0, this attribute is set to the height of the text string in 1/100mm. Range: Integer
ff_text_height_code	When reading FF, if thojd < 0, this attribute is set to the height code of the text string. Range: Integer
trikt	The angle of the string in degrees counterclockwise from horizontal. Range: 0.0 to +360.0
tjust	The anchor point for text (0 to 9) Range: 0 to 9 for text; 0 = decimal point for decimal text
tskala	The basic scale for text Range: Integer > 0
tstil	The text style Range: Integer > 0
tsparr	The text expansion increase in length of string given in % 0 = no expansion 100 = doubling of length Range: Integer > 0
