Last week, LibreOffice community branched out the version 4.3<\/a> in preparation of the next release in July. We had already introduced one of the new interoperability features that will be part of that release in the previous post in this series<\/a>, and now we will continue explaining how OOXML theme colors will be preserved in LibreOffice.<\/p>\n

Theme colors have a prominent place in the color palette in the latest Microsoft Office versions, as you can see:
\n\"Word<\/a><\/p>\n

They consist on a palette of ten colors, each one of them with five more variations. When a user changes the document theme, a new palette of colors will be loaded and any objects in the document that used one of those colors will be updated with the corresponding one from the new palette.<\/p>\n

In the XML document, a theme color is identified by a name, and its variations are implemented with two attributes: shade<\/em> to lighten the color and tint<\/em> to darken it.<\/p>\n

This is an example of theme color applied to the characters in a text run – a chunk of text with the same properties. In the run properties (rPr<\/em>) we find the following tag (reference<\/a>):
\n[code language=”xml”]
\n<w:rPr>
\n <w:color w:val="E5B8B7" w:themeColor="accent2" w:themeTint="66"\/>
\n<\/w:rPr>
\n[\/code]
\n\"Theme<\/a><\/p>\n

This is the theme color named accent2 darkened a 66%. The w:val<\/em> property indicates the RGB code of the final color, it’s ignored if w:themeColor<\/em> is present.<\/p>\n

The preservation of this tag is simple:<\/p>\n
