About This Chapter

This chapter describes the PostScript fonts included in the Simplified Chinese Solaris operating environment, what you need to use them, and how to edit them.

Display PostScript System (DPS)

The Simplified Chinese Solaris operating environment provides PostScript fonts in the Display PostScript System (DPS). This section describes what you need to use DPS in Simplified Chinese Solaris software. For further details, see Programming the Display PostScript System with X, published by Adobe® Systems.

Using Simplified Chinese PostScript Fonts and DPS Facilities

The Simplified Chinese Solaris operating environment includes the fonts listed in the following table. You can use any of the Simplified Chinese fonts just as you would use Roman fonts.

Table 7-1 Simplified Chinese Solaris Operating Environment PostScript Fonts

The following figure shows a sample of Song-Medium.

Creating Composite Roman and Simplified Chinese Fonts

You can create composite fonts using any one Roman font and the Simplified Chinese fonts. For example, the following PostScript code defines a composite font, Times-Italic+Kai-Medium, which uses Times-Italic for ASCII characters and Kai-Medium font for Simplified Chinese characters:

/makeEUCfont {
        /AsianFont exch def
        /WestFont  exch def
        /NewFont   exch def

        /CIDInit /ProcSet findresource 
        begin
          NewFont [ AsianFont WestFont ]
          beginrearrangedfont
            1 usefont
            1 beginbfrange
              <00> <7e>  <00>
            endbfrange
          endrearrangedfont
        end
  } bind def

  /LC_Times-Roman /Times-Roman /Kai-Medium makeEUCfont

Using Simplified Chinese Fonts in DPS Programming

You can use Simplified Chinese fonts just as you use Roman fonts in DPS wrap definitions. The following code sample creates the display in the next figure.

	defineps PSWDisplayText(char *text)
        	/pointSize 50 def
        	/Helvetica pointSize selectfont
        	(Hello World) stringwidth pop 2 div neg 0 moveto
        	(Hello World) show
	
        	/cpSize 40 def
        	/Song-Medium cpSize selectfont
        	(text) stringwidth pop 2 div neg pointSize neg moveto
        	(text) show
	endps

You can call PSWDisplayText(Chinese text) in a C program to display the designated Chinese text. For an example see the following figure.

Simplified Chinese Solaris software provides TrueType support in DPS.

Converting BDF to PCF Format

Before applications can use the modified BDF file, it must be converted to a PCF format file.

• Make the edited font usable by the Simplified Chinese Solaris operating environment by converting to X11 PCF format as follows:

system% bdftopcf -o myfont14.pcf myfont.bdf

For more information, see the bdftopcf(1) man page.

Installing and Checking the Edited Font

1. To add a new bitmap, move the .pcf font file into your font directory. You may compress the .pcf font file before moving it to your font directory:

   system% compress myfont14.pcf

   
   

2. Run the following commands in your font directory.

   The .bdf file should not be in the font directory.

   system% cat >> fonts.alias -new-myfont-medium-r-normal--16-140-75-75-c-140-gb2312.1980-0 Myfont-Medium14' ^D system% mkfontdir system% xset +fp `pwd`

   
   

3. You can view your font using the X Font Displayer (xfd) by typing:

   system% xfd -fn Myfont-Medium14

   
   

All Simplified Chinese fonts have XLFD font names, and you can use the xlsfonts utility to display these names as follows:

system% xlsfonts | grep gb2312

Creating Characters With sdtudctool

You can create new characters using the drawing tools in the sdtudctool utility. (For information on modifying a font, see Editing Fonts With fontedit on page 83.) Following is the user defined characters code range for different SCH locales:

Table 7-2 Code Points for locales

The sdtudctool utility supports bitmap, Type 1, and CID fonts. You can also specify a font size for the new characters. This section contains procedures for using sdtudctool.

Using sdtudctool

This section contains instructions for creating, inputing and printing new characters with the sdtudctool utility and other tools. For example inzh locale, use the following procedure.

1. To start the utility, type the following command:

   system% sdtudctool

   
   

   The following window appears.

   

2. Click the Character button.

   The following dialog box appears:

   

3. Specify the code position of the new character.

4. Create the outline or bitmap for the character using the drawing tools.

5. Click Save to save the character.

6. Continue creating new characters.

7. When you are finished, choose Save from the File menu to save the changes to your environment.

   The new character(s) are saved in $HOME/.Xlocale/{locale}/fonts/UDC.. .
