NAME

       avg_showfont - font enumeration and preview tool

SYNOPSIS

       avg_showfont [fontname] [text]

DESCRIPTION

       List available font faces and generate preview of their variants.

       If  invoked  without  arguments, avg_showfont generates a list of font family names and prints them on the console.  Fontconfig is used for
       font discovery. Fonts are searched for in the system font path and in $PWD/fonts.

       If fontname is specified, the chosen font is displayed in a window, with one line for each available variant.

       If supplied, the optional text argument is used instead of the variant name in the sample text.

NAME

       dtk_load_font - Load an font

SYNOPSIS

       #include <drawtk.h>

       dtk_hfont dtk_load_font(const char *fontname);
       void dtk_destroy_font(dtk_hfont font);

DESCRIPTION

       dtk_load_font()	loads  the font specified by fontname argument. This should be the path of a file whose file format can be any of the file
       format supported by the freetype library (TrueType and Type 1 among many others) or a font description  pattern	understood  by	fontconfig
       (like  "Times new roman:bold"). dtk_load_font() will first interpret fontname as a font filename and then, if this fail interpret as a font
       pattern and load the closest font available on the system.

       Upon creation, the font data is then tracked by an internal resource manager so that the next call using the same  fontname  argument  will
       return the same font handle, thus sparing the resources of the system.

       There  is  no need for a valid window to create successfully a font, i.e.  font loading is completely decoupled from the creation of others
       resources and can even be created in one thread to be used in another one.

       dtk_destroy_font() frees the resource referenced by font. If the font is used several times, i.e. several call to dtk_load_font() with  the
       same file path, it decreases the number of uses by one.

       Calling	dtk_destroy_texture()  on  each created font is currently not mandatory since all font remaining fonts are destroyed when the last
       window is closed. However, if no window can be closed (for example, no window has been created), dtk_destroy_font()  should  be	called	on
       each created font to avoid any memory leak.

RETURN VALUE

       In case of success, the dtk_load_font() returns the handle to the loaded font. In case of failure, NULL is returned.

       dtk_destroy_texture() does not return any value.

THREAD SAFETY

       dtk_load_font() and dtk_destroy_texture() are thread-safe.
