.PP
.Vb 1
\& my $version = SDL::TTF::linked_version();
.Ve
.PP
This gives you the SDL::Version object which SDL_ttf lib is used on the system.
No prior initialization needs to be done before these function is called.
.PP
Example:
.PP
.Vb 2
\& use SDL::TTF;
\& use SDL::Version;
\& 
\& my $version = SDL::TTF::linked_version();
\& 
\& printf("got version: %d.%d.%d\en", $version\->major, $version\->minor, $version\->patch);

\fIcompile_time_version\fR
.IX Subsection "compile_time_version"
.PP
.Vb 1
\& my $version = SDL::TTF::compile_time_version();

This gives you the SDL::Version object which SDL_ttf was present at compile time.
.PP
\fIinit\fR
.IX Subsection "init"
.PP
.Vb 1
\& my $success = SDL::TTF::init();
.Ve
.PP
Initialize the truetype font API.
This must be called before using other functions in this library, except SDL::TTF::was_init and SDL::TTF::linked_version.
SDL does not have to be initialized before this call.
.PP
Returns: \f(CW0\fR on success, \f(CW\-1\fR on any error.
.PP
\fIwas_init\fR
.IX Subsection "was_init"
.PP
.Vb 1
\& my $was_init = SDL::TTF::was_init();
.Ve
.PP
Query the initialization status of the truetype font API.
You may, of course, use this before SDL::TTF::init to avoid initializing twice in a row. Or use this to determine if you need to 
call SDL::TTF::quit.
.PP
\fIquit\fR
.IX Subsection "quit"
.PP
.Vb 1
\& SDL::TTF::quit();
.Ve
.PP
Shutdown and cleanup the truetype font API.
After calling this the SDL::TTF functions should not be used, excepting SDL::TTF::was_init. You may, of course, use 
SDL::TTF::init to use the functionality again

.PP
.Vb 1

Load file for use as a font, at the given size. This is actually \f(CW\*(C`SDL::TTF::open_font_index(..., ..., $index = 0)\*(C'\fR. This can load TTF, OTF and FON files.
.PP
Returns: a SDL::TTF::Font object. \f(CW\*(C`undef\*(C'\fR is returned on errors.

.IX Subsection "open_font_RW"
.PP
.Vb 1
\& my $font = SDL::TTF::open_font_RW($rwops_object, $free, $point_size);
.Ve
.PP
This is the same as SDL::TTF::open_font, except you can pass an SDL::RWOps\-object. If you pass true as \f(CW$free\fR, the SDL::RWOps\-object
will be freed by SDL_ttf library. Don't do this, perl will free this object for you.
.PP
Example:
.PP
.Vb 1
\& my $font = SDL::TTF::open_font_RW(SDL::RWOps\->new_file($font_file, \*(Aqr\*(Aq), 0, 24);

This is the same as SDL::TTF::open_font_index, except you can pass an SDL::RWOps\-object. If you pass true as \f(CW$free\fR, the

.Vb 1
\& SDL::TTF::byte_swapped_unicode( $bool );

.PP
This function tells SDL_ttf whether UNICODE (2 bytes per character) text is generally byteswapped. A \f(CW\*(C`UNICODE_BOM_NATIVE\*(C'\fR or 
\&\f(CW\*(C`UNICODE_BOM_SWAPPED\*(C'\fR character in a string will temporarily override this setting for the remainder of that string, however this setting

.Ve
.PP
set_font_style
.IX Subsection "set_font_style"
.PP
.Vb 1
\& SDL::TTF::set_font_style($font, $style);
.Ve
.PP
Set the rendering style of the loaded font.
.PP
\&\fBNote\fR: \f(CW\*(C`TTF_STYLE_UNDERLINE\*(C'\fR may cause surfaces created by \f(CW\*(C`SDL::TTF::render_glyph_*\*(C'\fR functions to be extended vertically, downward only, 
to encompass the underline if the original glyph metrics didn't allow for the underline to be drawn below. This does not change the math used 
to place a glyph using glyph metrics.
On the other hand \f(CW\*(C`TTF_STYLE_STRIKETHROUGH\*(C'\fR doesn't extend the glyph, since this would invalidate the metrics used to position the glyph when 
blitting, because they would likely be extended vertically upward. There is perhaps a workaround, but it would require programs to be smarter 
about glyph blitting math than they are currently designed for.
Still, sometimes the underline or strikethrough may be outside of the generated surface, and thus not visible when blitted to the screen. In 
this case, you should probably turn off these styles and draw your own strikethroughs and underlines.
.PP
get_font_outline
.IX Subsection "get_font_outline"

.PP
set_font_hinting
.IX Subsection "set_font_hinting"
.PP
.Vb 1
\& SDL::TTF::set_font_hinting($font, $hinting);
.Ve
.PP
Set the hinting of the loaded font. You should experiment with this setting if you know which font you are using beforehand, especially when 
using smaller sized fonts. If the user is selecting a font, you may wish to let them select the hinting mode for that font as well.
.PP
\&\fBNote\fR: at least SDL_ttf 2.0.10 needed
.PP
Example:
.PP
.Vb 1
\& SDL::TTF::set_font_hinting($font, TTF_HINTING_LIGHT);

get_font_kerning
.IX Subsection "get_font_kerning"
.PP
.Vb 1
\& my $kerning_enabled = SDL::TTF::get_font_kerning($font);
.Ve
.PP
Get the current kerning setting of the loaded font.
.PP
Returns: \f(CW0\fR(zero) if kerning is disabled. A non-zero value is returned when enabled. The default for a newly loaded font is enabled(\f(CW1\fR).
.PP
\&\fBNote\fR: at least SDL_ttf 2.0.10 needed
.PP
\&\fBNote\fR: This function returns wrong values: See <http://bugzilla.libsdl.org/show_bug.cgi?id=973>
.PP
set_font_kerning
.IX Subsection "set_font_kerning"
.PP
.Vb 1
\& SDL::TTF::set_font_kerning($font, $kerning_enabled);
.Ve
.PP
Set whether to use kerning when rendering the loaded font. This has no effect on individual glyphs, but rather when rendering whole strings of 
characters, at least a word at a time. Perhaps the only time to disable this is when kerning is not working for a specific font, resulting in 
overlapping glyphs or abnormal spacing within words.
.PP
Pass \f(CW0\fR to disable kerning, 1 to enable.

.IX Subsection "Font metrics"
.PP
font_height
.IX Subsection "font_height"
.PP
.Vb 1
\& my $font_height = SDL::TTF::font_height($font);
.Ve
.PP
Get the maximum pixel height of all glyphs of the loaded font. You may use this height for rendering text as close together vertically as 
possible, though adding at least one pixel height to it will space it so they can't touch. Remember that SDL_ttf doesn't handle multiline 
printing, so you are responsible for line spacing, see the SDL::TTF::font_line_skip as well.
.PP
font_ascent
.IX Subsection "font_ascent"
.PP
.Vb 1
\& my $font_ascent = SDL::TTF::font_ascent($font);
.Ve
.PP
Get the maximum pixel ascent of all glyphs of the loaded font. This can also be interpreted as the distance from the top of the font to the 
baseline.
It could be used when drawing an individual glyph relative to a top point, by combining it with the glyph's \f(CW\*(C`maxy\*(C'\fR metric to resolve the top 
of the rectangle used when blitting the glyph on the screen.
.PP
Example:
.PP
.Vb 1
\& my ($minx, $maxx, $miny, $maxy, $advance) = @{ SDL::TTF::glyph_metrics($font, "\e0M") };
\&
\& $rect\->y( $top + SDL::TTF::font_ascent($font) \- $maxy );
.Ve
.PP
font_descent
.IX Subsection "font_descent"
.PP
.Vb 1
\& my $font_descent = SDL::TTF::font_descent($font);
.Ve
.PP
Get the maximum pixel descent of all glyphs of the loaded font. This can also be interpreted as the distance from the baseline to the bottom of 
the font.
It could be used when drawing an individual glyph relative to a bottom point, by combining it with the glyph's \f(CW\*(C`maxy\*(C'\fR metric to resolve the top 
of the rectangle used when blitting the glyph on the screen.
.PP
Example:
.PP
.Vb 1
\& my ($minx, $maxx, $miny, $maxy, $advance) = @{ SDL::TTF::glyph_metrics($font, "\e0M") };
\&
\& $rect\->y( $bottom \- SDL::TTF::font_descent($font) \- $maxy );
.Ve
.PP
font_line_skip
.IX Subsection "font_line_skip"
.PP
.Vb 1
\& my $font_line_skip = SDL::TTF::font_line_skip($font);
.Ve
.PP
Get the recommended pixel height of a rendered line of text of the loaded font. This is usually larger than the SDL::TTF::font_height of the 
font.
.PP
\fIFace attributes\fR
.IX Subsection "Face attributes"
.PP
font_faces
.IX Subsection "font_faces"
.PP
.Vb 1
\& my $font_faces = SDL::TTF::font_faces($font);
.Ve
.PP
Get the number of faces ("sub-fonts") available in the loaded font. This is a count of the number of specific fonts (based on size and style 
and other typographical features perhaps) contained in the font itself.
.PP
font_face_is_fixed_width
.IX Subsection "font_face_is_fixed_width"
.PP
.Vb 1
\& my $font_face_is_fixed_width = SDL::TTF::font_face_is_fixed_width($font);
.Ve
.PP
Test if the current font face of the loaded font is a fixed width font. Fixed width fonts are monospace, meaning every character that exists 
in the font is the same width, thus you can assume that a rendered string's width is going to be the result of \f(CW\*(C`glyph_width * string_length\*(C'\fR.
.PP
Returns: \f(CW\*(C`>0\*(C'\fR if font is a fixed width font. \f(CW0\fR if not a fixed width font.
.PP
font_face_family_name
.IX Subsection "font_face_family_name"

.Vb 1
\& my $font_face_family_name = SDL::TTF::font_face_family_name($font);

Example:

.Vb 1
