5.1    DECwindows Fonts

The Tru64 UNIX operating system software provides the Thai DECwindows fonts described in Table 5-1 in various sizes for 75 dpi (dot-per-inch) display devices.

Table 5-1: Thai Screen Fonts

These mandatory fonts are available when you install the Thai variant. In addition to these Thai fonts, several miscellaneous screen fonts are provided in the Thai DECterm and toolkit.

No 100 dpi Thai fonts are provided in the kit. To allow you to use the Thai fonts on 100 dpi display devices, a font alias file is provided to map the 75 dpi font names to the respective 100 dpi font names.

5.1.1    XLFD Font Names

You must specify the DECwindows font names in XLFD (X Logical Font Description) format in your application programs or in the application resource files. You can specify wildcards (*) for any fields in the font names.

You can use the following font names for either 75 dpi or 100 dpi display devices. To explicitly state the display resolution, you can specify 75 or 100 in the X- and Y-resolution fields, that is, the asterisks in the following XLFD names.

Screen family font names in XLFD format:

5.1.3    Specifying Fonts in DECwindows Applications

Table 5-2 shows the default font list used in the Motif Toolkit.

Table 5-2: Thai Default Font List

To override the default font list of a Thai DECwindows application, you should specify the ISO Latin-1 and Thai fonts as well as the Thai fontset when creating widget instances. For details, see Writing Software for the International Market.

5.1.4    Outline Fonts

The Tru64 UNIX operating system software provides the Thai outline fonts shown in Table 5-3.

Table 5-3: Thai Outline Fonts

These Thai outline fonts can be used for:

• Printing on PostScript printers. For details see Chapter 8, Thai Printing Support.
• Displaying through the R6 X Windows System Type 1 rasterizer. To use these outline fonts, you must add the $I18NPATH/usr/lib/X11/fonts/Type1UPC directory to your font path with the following command:

% xset +fp $I18NPATH/usr/lib/X11/fonts/Type1UPC

• Displaying through Display PostScript. You can view PostScript files with Thai characters using the CDA Viewer or through the Display PostScript extension.

5.2    XLFD Font Names of Thai Outline Fonts

To use the Thai outline fonts through the Type 1 rasterizer, you can specify the font names in XLFD format in your application programs or in the application resource files, just as you do with ordinary DECwindows bitmap fonts.

To specify the XLFD font name of an outline font, you can replace the fields currently marked with 0 (zero) with the following information:

1. Field 1 - The font height in number of dots. Usually, an asterisk is entered in this field.
2. Field 2 - The font height in point size. For example, you can enter 240 to specify a 24 point font.
3. Fields 3 and 4 - The X- and Y-resolution. Usually, they have the value of 75 or 100.
4. Field 5 - The average font width in point size. Usually, an asterisk is put in this field.

For example, if you want to use a 48 point font of the AngsanaUPC family in bold-italic style for a 100 dpi display device, you would specify:

-upc-angsana-bold-i-normal--*-480-100-100-p-*-tis620.2533-1
