| + | ====Syntax of gettextsettings ==== | ||

| + | |||
| + | |||
| + | ==== Description of gettextsettings ==== | ||
| + | <code c> | ||
| + | gettextsettings fills the textsettingstype structure pointed to by | ||
| + | textinfo with information about the current text font, direction, size, | ||
| + | and justification. The textsettingstype structure used by gettextsettings | ||
| + | is defined in graphics.h as follows: | ||
| + | struct textsettingstype { | ||
| + | int font; | ||
| + | int direction; | ||
| + | int charsize; | ||
| + | int horiz; | ||
| + | int vert; | ||
| + | }; | ||
| + | See settextstyle for a description of these fields. | ||
| + | </code> | ||
