PDFlib 8 Windows COM/.NET Tutorial

loading option list for the fallbackfonts option to add a user-defined (gaiji) character
from an EUDC font to the loaded font:
fallbackfonts={
{fontname=EUDC encoding=unicode forcechars=U+E000 fontsize=140% textrise=-20%}
}
Once a base font has been loaded with this fallback font configuration, the EUDC character
can be used within the text without any need to change the font.
With SING fonts the Unicode value doesn’t have to be supplied since it will automatically
be determined by PDFlib:
fallbackfonts={
{fontname=PDFlibWing encoding=unicode forcechars=gaiji}
}
Preparing EUDC fonts. You can use the EUDC editor available in Windows to create
custom characters for use with PDFlib. Proceed as follows:
> Use the eudcedit.exe to create one or more custom characters at the desired Unicode
position(s).
> Locate the EUDC.TTE file in the directory \Windows\fonts and copy it to some other directory.
Since this file is invisible in Windows Explorer use the dir and copy commands
in a DOS box to find the file. Now configure the font for use with PDFlib, using
one of the methods discussed in (see Section 5.4.4, »Searching for Fonts«, page
132):
p.set_parameter("FontOutline", "EUDC=EUDC.TTE");
p.set_parameter("SearchPath", "...directory name...");
or place EUDC.TTE in the current directory.
As an alternative to this explicit font file configuration you can use the following
function call to configure the font file directly from the Windows directory. This way
you will always access the current EUDC font used in Windows:
p.set_parameter("FontOutline", "EUDC=C:\Windows\fonts\EUDC.TTE");
> Integrate the EUDC font into any base font using the fallbackfonts option as described
above. If you want to access the font directly, use the following call to load
the font in PDFlib:
font = p.load_font("EUDC", "unicode", "");
as usual and supply the Unicode value(s) chosen in the first step to output the characters.
6.5.4 OpenType Layout Features for advanced CJK Text Output
As detailed in Section 6.3, »OpenType Layout Features«, page 158, PDFlib supports advanced
typographic layout tables in OpenType and TrueType fonts. For example, Open-
Type features can be used to select alternative forms of the Latin glyphs with proportional
widths or half widths, or to select alternate character forms. Table 6.7 lists
OpenType features which are targeted at CJK text output.
