How to: Apply themes using Server Object Model in SharePoint 2013 Preview
One of new functionalities introduced in SharePoint 2013 Preview is new theming engine. Themes that are managed by this new engine don’t use Office Theme .thmx format and can’t be created using PowerPoint like it was case before. New themes are based on set of xml files stored in Theme Gallery “15” subfolder (on relative path _catalogs/theme/15):
- .spcolor files which define color palettes for components of SharePoint interface
- .spfont files which contain set of predefined font schemes.
There are 30 color palette and 3 font scheme files stored in this subfolder, but it is also possible to upload new .spcolor and .spfont files, as long as your files correspond to predefined XML format.
