int Font_CS = 0; Font_CS = PDF_load_font(p, "SimHei", 0, "unicode", "");需要注意的是，字体名可能与字体文件名不同，甚至相同的字体在不同语言的操作系统下字体名称会有所不同。在 Windows 环境下查看字体名，可双击该字体文件，窗口打开后的第一行字除结尾的 TrueType, OpenType 外为字体名。例如，调用安装在 Windows 系统中的字体： C:\WINDOWS\Fonts\SimHei.ttf ，双击该文件后，窗口的第一行为“黑体 TrueType” 。则该文件的字体名为“黑体”。在 PDFlib 中若要调用多字节的文件名，须以 BOM UTF8 的形式。 “黑体”的 BOM UTF8 的形式为“ \xEF\xBB\xBF\xE9\xBB\x91\xE4\xBD\x93 ”。
PDF_load_font(p, "\xEF\xBB\xBF\xE9\xBB\x91\xE4\xBD\x93", 0, "unicode", "");在英文WINDOWS下则应使用
PDF_load_font(p, "SimHei", 0, "unicode", "");(小技巧: 我们可以使用Windows2000/XP自带的notepad获得UTF8编码,具体方法举例:在notepad中输入"黑体"并保存, 保存时在编码下拉框中选择UTF-8, 然后用UltraEdit,WinHex,VC等可以进行二进制编辑的工具打开该文件即可取得带BOM的UTF8字符串)
Font_CS= PDF_load_font(p, "C:\\Program Files\\Adobe\\Acrobat 7.0\\Resource\\CIDFont\\ AdobeSongStd-Light", 0, "unicode", "");但这里有个例外，那就是.ttc(TrueType Collection)字体。.ttc是集合字体文件，每个文件中含有多种字体。所以用户不能用文件名调用字体，而是要用真正的字体名。比方说，我们知道C:\WINDOWS\Fonts\MSGOTHIC.TTC 包含三种字体依次名为MS Gothic，MS PGothic，和MS UI Gothic。我们可以用以它们相应的字体名调用：
int Font_E = 0; Font_E= PDF_load_font(p, "MS Gothic", 0, "winansi", ""); /* Use MS Gothic */ PDF_setfont(p, Font_E, 20); PDF_show_xy(p, "MS Gothic font:" , 50, 800)； Font_E= PDF_load_font(p, "MS PGothic", 0, "winansi", ""); /* Use MS PGothic */ …… Font_E= PDF_load_font(p, "MS UI Gothic", 0, "winansi", ""); /* Use MS UI Gothic */可是我们经常并不清楚.ttc里包含哪些字体。在这种情况PDFlib提供了另一种调用方式—索引（Index）。用此方式，首先须给字体文件名一个别名，然后在别名后加冒号再加数字（0表示文件中第一种字体，1 表示第二种，依次类推。）
int Font_E = 0; /* Give “C:\WINDOWS\Fonts\MSGOTHIC.TTC an alias “gothic” */ PDF_set_parameter(p, "FontOutline", "gothic=C:\\WINDOWS\\Fonts\\MSGOTHIC.TTC"); Font_E= PDF_load_font(p, "gothic:0", 0, "winansi", ""); /* Use MS Gothic */ Font_E= PDF_load_font(p, "gothic:1", 0, "winansi", ""); /* Use MS PGothic */ Font_E= PDF_load_font(p, "gothic:2", 0, "winansi", ""); /* Use MS UI Gothic */
