Function Documentation

◆ change_fonto_utf8()

void change_fonto_utf8 ( utf8_str pstr,
enum font_origin  origin 
)

Change font size of text to that from given origin.

Definition at line 585 of file gui_string.c.

◆ change_ptsize_utf8()

void change_ptsize_utf8 ( utf8_str pstr,
Uint16  new_ptsize 
)

Change font size of text.

Definition at line 560 of file gui_string.c.

◆ convert_utf8_str_to_const_surface_width()

bool convert_utf8_str_to_const_surface_width ( utf8_str pstr,
int  width 
)

Wrap text to make it fit to given screen width.

Definition at line 450 of file gui_string.c.

◆ copy_chars_to_utf8_str()

utf8_str * copy_chars_to_utf8_str ( utf8_str pstr,
const char pchars 
)

Convert char array to utf8_str. Pointer to target string is needed as parameter, but also returned for convenience.

Definition at line 249 of file gui_string.c.

◆ create_text_surf_from_utf8()

SDL_Surface * create_text_surf_from_utf8 ( utf8_str pstr)

Generic function to create surface with any kind of text, single line or multiline, drawn.

Definition at line 426 of file gui_string.c.

◆ create_text_surf_smaller_than_w()

SDL_Surface * create_text_surf_smaller_than_w ( utf8_str pstr,
int  w 
)

Create surface with text drawn to it. Wrap text as needed to make it fit in given width.

Definition at line 540 of file gui_string.c.

◆ create_utf8_multi_surf()

static SDL_Surface * create_utf8_multi_surf ( utf8_str pstr)
static

Create surface with multiline text drawn.

Definition at line 343 of file gui_string.c.

◆ create_utf8_str()

utf8_str * create_utf8_str ( char in_text,
size_t  n_alloc,
Uint16  ptsize 
)

Create utf8_str struct with ptsize font. If ptsize is zero, use theme's default font size.

Font will be loaded or aliased with existing font of that size. in_text must be allocated in memory (fc_malloc() / fc_calloc())

Definition at line 204 of file gui_string.c.

◆ create_utf8_str_fonto()

utf8_str * create_utf8_str_fonto ( char in_text,
size_t  n_alloc,
enum font_origin  origin 
)

Create utf8_str struct with font size from given origin.

Font will be loaded or aliased with existing font of that size. in_text must be allocated in memory (fc_malloc() / fc_calloc())

Definition at line 239 of file gui_string.c.

◆ create_utf8_surf()

static SDL_Surface * create_utf8_surf ( utf8_str pstr)
static

Create Text Surface from utf8_str

Definition at line 296 of file gui_string.c.

◆ fonto_ptsize()

static Uint16 fonto_ptsize ( enum font_origin  origin)
static

Convert font_origin to ptsize value

Definition at line 166 of file gui_string.c.

◆ free_font_system()

void free_font_system ( void  )

Free all fonts.

Definition at line 699 of file gui_string.c.

◆ load_font()

static TTF_Font * load_font ( Uint16  ptsize)
static

Load font of given pointsize.

Definition at line 595 of file gui_string.c.

◆ unload_font()

void unload_font ( Uint16  ptsize)

Free font of given pointsize.

Definition at line 654 of file gui_string.c.

◆ utf8_str_size()

void utf8_str_size ( utf8_str pstr,
SDL_Rect fill 
)

Adjust font sizes for small screen. Calculate display size of string.

Definition at line 102 of file gui_string.c.

◆ write_utf8()

int write_utf8 ( SDL_Surface dest,

Sint16  y,
utf8_str pstr 
)

Blit text to surface.
