Info

When stroking text, graphics state parameters such as linewidth and color will be applied to the glyph outline. The rendering mode has no effect on text displayed using a Type 3 font. Cookbook Full code samples can be found in the Cookbook topics text_output/text_as_clipping_path and text_output/invisible_text. Text color. Text will usually be display in the current fill color, which can be set using setcolor( ). However, if a rendering mode other than 0 has been selected, both stroke and fill color may affect the text depending on the selected rendering mode. Cookbook A full code sample can be found in the Cookbook topic text_output/starter_textline. 156 Chapter 6: Text Output (Edition for COM, .NET, and REALbasic)
6.3 OpenType Layout Features Cookbook Full code samples can be found in the Cookbook topics text_output/starter_opentype and font/opentype_feature_tester. 6.3.1 Supported OpenType Layout Features PDFlib supports enhanced text output according to additional information in some fonts. These font extensions are called OpenType layout features. For example, a font may contain a liga feature which includes the information that the f, f, and i glyphs can be combined to form a ligature. Other common examples are small caps in the smcp feature, i.e. uppercase characters which are smaller than the regular uppercase characters, and old-style figures in the onum feature with ascenders and descenders (as opposed to lining figures which are all placed on the baseline). Although ligatures are a very common OpenType feature, they are only one of many dozen possible features. An overview of the OpenType format and OpenType feature tables can be found at www.microsoft.com/typography/developers/opentype/default.htm PDFlib supports the following groups of OpenType features: > OpenType features for Western typography listed in Table 6.1; these are controlled by the features option. > OpenType features for Chinese, Japanese, and Korean text output listed in Table 6.7; these are also controlled by the features option, and are discussed in more detail in Section 6.5.4, »OpenType Layout Features for advanced CJK Text Output«, page 176. > OpenType features for complex script shaping and vertical text output; these are automatically evaluated subject to the shaping and script options (see Section 6.4, »Complex Script Output«, page 164). The vert feature is controlled by the vertical font option. > OpenType feature tables for kerning; however, PDFlib doesn’t treat kerning as Open- Type feature because kerning data may also be represented with other means than OpenType feature tables. Use the readkerning font option and the kerning text option instead to control kerning (see Section 6.2.2, »Kerning«, page 154). More detailed descriptions of OpenType layout features can be found at www.microsoft.com/typography/otspec/featuretags.htm Identifying OpenType features. You can identify OpenType feature tables with the following tools: > The FontLab font editor is a an application for creating and editing fonts. The free demo version (www.fontlab.com) displays and previews OpenType features > DTL OTMaster Light (www.fonttools.org) is a free application for viewing and analyzing fonts, including their OpenType feature tables. > Microsoft’s free »font properties extension« 1 displays a list of OpenType features available in a font (see Figure 6.3). > PDFlib’s info_font( ) interface can also be used to query supported OpenType features (see »Querying OpenType features programmatically«, page 162). 1. See www.microsoft.com/typography/TrueTypeProperty21.mspx 6.3 OpenType Layout Features 157
