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.
