PDF Chemistry

Image maps are now fully supported in DITA-based output. The shapes that are defined in the image map are rendered in the output as clickable areas within the image and the list of links are presented below the image. Two new parameters (-show.image.map.area.numbers and -show.image.map.area.shapes) are used to instruct the publishing engine to make the numbers and shapes visible in the output. For more details, see How to Use Image Maps.

A line break at a hyphen character can cause PDF readers to join the lines but discard the hyphen character when copying and pasting content. A new extension property (-oxy-avoid-breaking-line-at-hypens) can be used to avoid this type of line break.

Latin ligatures are now enabled by default. This means that, depending on the capabilities of your particular font, high quality text rendering is possible for Latin-based scripts.

Chemistry now supports advanced OpenType font settings, such as font-variant-ligatures (for ligatures) and font-variant-alternates (for stylesets).

Additional fallback fonts were added to help avoid having missing characters in the PDF output. For example, DejaVu fonts were added as fallbacks for the SansSerif, Serif, and Monospace font families.

Now you can round border corners using the border-radius CSS property. The background-color property also follows the defined border shape.

The global CSS property values initial and unset are now allowed in many of the supported CSS properties.

The widows and orphans CSS properties are now applied to the lists, as well as paragraphs (the default value is 2). This means that a list that spans consecutive pages will have either none or at least 2 text lines on each of the pages.

Support was added for CFF (Compact Font Format) fonts packed in a TTC font collection.

It is now possible to place links over parts of SVG images that point to other document sections. This is useful if, for example, you want to use the SVG graphic as a type of table of contents or image map.

The new pdf.version transformation parameter can be used to specify the version of the produced PDF.
