cpdf_set_font

Select the current font face and size (PHP 3 >= 3.0.8, PHP 4, PHP 5 <= 5.0.4)
bool cpdf_set_font ( int pdf_document, string font_name, float size, string encoding )

The cpdf_set_font() function sets the current font face, font size and encoding. Currently only the standard postscript fonts are supported. 如果成功则返回 TRUE,失败则返回 FALSE

The last parameter encoding can take the following values: "MacRomanEncoding", "MacExpertEncoding", "WinAnsiEncoding", and "NULL". "NULL" stands for the font's built-in encoding.

See the ClibPDF Manual for more information, especially how to support Asian fonts.
