Using Themes

EPPlus 5 support creating and loading themes. Themes can be created or loaded via the Workbook.ThemeManager. A theme can be exported from Excel using the thmx format an then loaded via EPPLus:

   package.Workbook.ThemeManager.Load(FileInputUtil.GetFileInfo("15-ChartsAndThemes", "integral.thmx"));

The theme can then be altered via the ThemeManager.CurrentTheme property

//Change the color of the Accent1 theme color.
package.Workbook.ThemeManager.CurrentTheme.ColorScheme.Accent1.SetRgbColor(Color.FromArgb(32, 78, 224));
