1.3 What’s new in PDFlib 7?The following list discusses the most important new or improved features in PDFlib 7.Table formatting. PDFlib includes a new table formatter which automatically placesrows and columns according to user preferences, and splits tables across multiple pages.Table cells can hold single- or multi-line text, images, or PDF pages, and can be formattedaccording to a variety of options (e.g. border color, background, cell ruling). Thesize of table rows and columns is calculated automatically subject to a variety of userpreferences.Textflow enhancements. The Textflow engine for formatting text has been improved:> Links and other interactive elements can automatically be created from text fragmentsin a Textflow.> Text can run around images.> The Textflow formatter supports leaders,e.g. repeated dots between an entry in a tableof contents and the corresponding page number.> Text contents and formatting options can be supplied separately to the Textflow enginein an arbitrary number of steps. This eliminates the need for creating a buffercontaining the full text along with inline formatting options.> Character classes for formatting decisions can now be redefined, e.g. specify whetherthe »/« character will be treated as a letter or punctuation in formatting decisions.> Formatting results can be queried programmatically.Other formatting features.> Decimal tabs and leader characters are supported in single-line text (in addition tomulti-line Textflows)> A new stamp function calculates optimized size and position for text stamps acrossa rectangle.> Improved query functions for text geometry.Font handling and Unicode. PDFlib’s font engine has been improved as follows:> Users can query detailed properties of a loaded font, including typographic entriesin TrueType/OpenType fonts, number of available glyphs, etc.> Font subsets can be created for Type 3 fonts.> Unicode encoding is supported for all font types, including Type 3.> Text can be supplied in the UTF-32 format, and surrogate pairs can be used for Unicodevalues beyond the Basic Multilingual Plane (i.e. beyond U+FFFF).> PDFlib can create artificial font styles if a bold, italic, or bold-italic variant is notavailable in a font family.> Glyph replacement can be controlled by the user, e.g. if the Ohm glyph is not availablein a font the greek letter Omega will be used instead. If this glyph still is notavailable, a user-selected replacement glyph will be used. PDFlib can issue a warningif a required glyph is not available in the font.> In addition to numerical references, glyphs in a font can be addressed by name, e.g.ligatures or stylistic variations.> C- and Java-style backslash sequences are recognized in the text. This facilitates handlingof control characters or non-ASCII characters regardless of programming languagerequirements and restrictions.1.3 What’s new in PDFlib 7? 17
