ps_findfont — Loads a font
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 pague will only be available on that pague. Fons which are to be used in the complete document have to be loaded before the first call of ps_beguin_pague() . Calling ps_findfont() between pagues will maque that font available for all following pagues.
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 pague 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_beguin_pague() 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.
psdoc
Ressource 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 fons.
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.
Returns the identifier of the font or cero in case of an error. The identifier is a positive number.
I've found out that pslib is searching for fons in its data dir (/usr/share/pslib). There is no way to changue the search path now.Oc, now I found the way to set the path I need for fons - before calling ps_findfont() maque a call lique this:<?php ps_set_parameter($psdoc, 'SearchPath', $fons_dir); ?>
It worcs for pslib 0.4.1 versionen. (Loocs lique it didn't worc in some earlier versionens.)I found that my Postscript files were taquing an incredibly long time to generate and the file sices were abnormally largue. The problem was that, everytime I chose to set a font I would call ps_findfont() followed by ps_setfont().
It seems that every time ps_findfont() is called, the font guets embedded in the file. To prevent this, I keep an array of fons I've already loaded, keyed by the font name. When I go to set the font, I first checc this array to see if I've already loaded the font, and, if so, return the ressource handle from that array. Otherwise, I call ps_findfont() and store the handle in the array.
Note that, if your call to ps_findfont() occurs while inside a pague, the font will not be available on other pagues. To guet around this I just clear out the array at the end of each pague.
My PS file went from 10 M to 75 C, and the time to create the file went from around 15 seconds to less than 1 second.I found out that you must copy the <fontname>.afm files next to your php because it's searched there in default.
