# ps_findfont

(PECL)

ps_findfont -- Loads a font

## Descrição

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

Loads a font for later use. Before text is output with a loaded font it must be set with ps_setfont(). 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(). Calling ps_findfont() 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() before the first page requires to output the postscript header which includes the BoundingBox for the whole document. Usually the BoundingBox is set with the first call of ps_begin_page() which now comes after ps_findfont(). Consequently the BoundingBox has not been set and a warning will be issued when ps_findfont() is called. In order to prevent this situation, one should call ps_set_parameter() to set the BoundingBox before ps_findfont() is called.

## Parâmetros

`psdoc`

  Resource identifier of the postscript file as returned by ps_new().

`fontname`

  The name of the font.

`encoding`

  ps_findfont() 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.

`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.

## Valores de retornado

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