On pdflib Chinese output (v)--artificial generation of bold and italic font

In general, each basic font will have additional fonts that change the glyph on its basis. For example, the font Arial has its additional font Arial Bold (bold), Arial Italic (italic), and Arial Bold Italic (Bold italic). Generally you can find or purchase the appropriate additional fonts.

But sometimes there is no strict requirement for a contingency, or for font glyphs. In such cases, we can use artificial glyph generation (Artificial font styles). The Artificial font styles is a feature of Acrobat that simulates the generation of bold, italic, and bold italic based on the basic glyphs. Pdflib supports this feature and complies with Acrobat's limitations on this feature. The current functionality is limited to:

1. Acrobat standard font, in the Simplified Chinese is the pdflib Stsong-light,adobesongstd-light-acro, and stsongstd-light-acro three Simplified Chinese fonts.

2. Pdflib can access the. OTF OpenType font and use the Encoding of Table 1.1 (see), and the "embedding" parameter is set to False.

The following is a related example--c source program (attached to the generated PDF file –pdflib_cs5.pdf).
