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.

ps_findfont - Loads a font

SYNOPSIS

       int ps_findfont (resource  $psdoc, string  $fontname, string  $encoding, [bool  $embed = false])

DESCRIPTION

	Loads a font for later use. Before text is output with a loaded font it must be set with ps_setfont(3). This function needs the adobe font
       metric file in order to calculate the space used up by the characters. A font which is loaded within a page will only be available on  that
       page.  Fonts  which  are  to be used in the complete document have to be loaded before the first call of ps_begin_page(3). Calling ps_find-
       font(3) between pages will make that font available for all following pages.

	The name of the afm file must be $fontname .afm. If the font shall be embedded the file $fontname .pfb containing the font outline must be
       present as well.

	Calling  ps_findfont(3)  before the first page requires to output the postscript header which includes the BoundingBox for the whole docu-
       ment. Usually the BoundingBox is set with the first call of ps_begin_page(3) which now comes after ps_findfont(3). Consequently the  Bound-
       ingBox  has  not  been  set and a warning will be issued when ps_findfont(3) is called. In order to prevent this situation, one should call
       ps_set_parameter(3) to set the BoundingBox before ps_findfont(3) is called.

PARAMETERS

	      o $psdoc
		- Resource identifier of the postscript file as returned by ps_new(3).

	      o $fontname
		- The name of the font.

	      o $encoding
		-ps_findfont(3) will try to load the file passed in the parameter $encoding. Encoding files are of the same syntax as  those  used
		by  dvips(1).  They contain a font encoding vector (which is currently not used but must be present) and a list of extra ligatures
		to extend the list of ligatures derived from the afm file. $encoding can be NULL or the  empty	string	if  the  default  encoding
		(TeXBase1)  shall be used.  If the encoding is set to builtin then there will be no reencoding and the font specific encoding will
		be used. This is very useful with symbol fonts.

	      o $embed
		- If set to a value >0 the font will be embedded into the document. This requires the font outline (.pfb file) to be present.

RETURN VALUES

	Returns the identifier of the font or zero in case of an error. The identifier is a positive number.
