Excel 主题和颜色
主题提供了具有命名样式、图形效果和工作簿中使用的其他对象的统一外观。例如,在 Office 和 Apex 主题中,Accent1 样式看起来各不相同。通常,你应用文档主题,然后根据自己的需要进行修改。
在 Microsoft Excel 中应用主题
获取和设置主题颜色
Aspose.Cells API 提供了自定义主题和颜色的功能。以下是几种实现主题颜色的方法和属性。
- Style.ForegroundThemeColor 属性可用于设置前景色。
- Style.BackgroundThemeColor 属性可用于设置背景颜色。
- Font.ThemeColor 属性可用于设置字体颜色。
- Workbook.getThemeColor 方法可用于获取主题颜色。
- Workbook.setThemeColor 方法可用于设置主题颜色。
以下示例演示如何获取和设置主题颜色。
以下示例使用了一个模板 XLSX 文件,获取了不同主题颜色类型的颜色,更改了颜色,然后保存了 Microsoft Excel 文件。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getDataDir(GetSetThemeColors.class); | |
// Instantiate Workbook object | |
// Open an exiting excel file | |
Workbook workbook = new Workbook(dataDir + "book1.xlsx"); | |
// Get the Background1 theme color | |
Color c = workbook.getThemeColor(ThemeColorType.BACKGROUND_1); | |
// Print the color | |
System.out.println("theme color Background1: " + c); | |
// Get the Accent2 theme color | |
c = workbook.getThemeColor(ThemeColorType.ACCENT_1); | |
// Print the color | |
System.out.println("theme color Accent2: " + c); | |
// Change the Background1 theme color | |
workbook.setThemeColor(ThemeColorType.BACKGROUND_1, Color.getRed()); | |
// Get the updated Background1 theme color | |
c = workbook.getThemeColor(ThemeColorType.BACKGROUND_1); | |
// Print the updated color for confirmation | |
System.out.println("theme color Background1 changed to: " + c); | |
// Change the Accent2 theme color | |
workbook.setThemeColor(ThemeColorType.ACCENT_1, Color.getBlue()); | |
// Get the updated Accent2 theme color | |
c = workbook.getThemeColor(ThemeColorType.ACCENT_1); | |
// Print the updated color for confirmation | |
System.out.println("theme color Accent2 changed to: " + c); | |
// Save the updated file | |
workbook.save(dataDir + "GetAndSetThemeColorBook.xlsx"); |
自定义主题
以下示例演示如何应用带有您所需颜色的自定义主题。该示例使用了在 Microsoft Excel 2007 中手动创建的样本模板文件。
模板 CustomThemeColor.xlsx 文件
下面的示例加载一个模板XLSX文件,为不同的主题颜色类型定义颜色,应用自定义颜色并保存Excel文件。
使用自定义主题颜色生成的文件
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getDataDir(CustomizingThemes.class); | |
// Define Color array (of 12 colors) for the Theme | |
Color[] carr = new Color[12]; | |
carr[0] = Color.getAntiqueWhite(); // Background1 | |
carr[1] = Color.getBrown(); // Text1 | |
carr[2] = Color.getAliceBlue(); // Background2 | |
carr[3] = Color.getYellow(); // Text2 | |
carr[4] = Color.getYellowGreen(); // Accent1 | |
carr[5] = Color.getRed(); // Accent2 | |
carr[6] = Color.getPink(); // Accent3 | |
carr[7] = Color.getPurple(); // Accent4 | |
carr[8] = Color.getPaleGreen(); // Accent5 | |
carr[9] = Color.getOrange(); // Accent6 | |
carr[10] = Color.getGreen(); // Hyperlink | |
carr[11] = Color.getGray(); // Followed Hyperlink | |
// Instantiate a Workbook | |
// Open the spreadsheet file | |
Workbook workbook = new Workbook(dataDir + "book1.xlsx"); | |
// Set the custom theme with specified colors | |
workbook.customTheme("CustomeTheme1", carr); | |
// Save as the excel file | |
workbook.save(dataDir + "CustomThemeColor.xlsx"); |
使用主题颜色
下面的示例根据工作簿的默认主题颜色类型,应用单元格的前景色和字体颜色。它还将Excel文件保存到磁盘。
执行代码时会生成以下输出。
工作表的单元格 D3 应用的主题颜色
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getDataDir(UseThemeColors.class); | |
// Instantiate a Workbook | |
Workbook workbook = new Workbook(); | |
// Get cells collection in the first (default) worksheet | |
Cells cells = workbook.getWorksheets().get(0).getCells(); | |
// Get the D3 cell | |
Cell c = cells.get("D3"); | |
// Get the style of the cell | |
Style s = c.getStyle(); | |
// Set background color for the cell from the default theme Accent2 color | |
s.setBackgroundThemeColor(new ThemeColor(ThemeColorType.ACCENT_2, 0.5)); | |
// Set the pattern type | |
s.setPattern(BackgroundType.SOLID); | |
// Get the font for the style | |
Font f = s.getFont(); | |
// Set the theme color | |
f.setThemeColor(new ThemeColor(ThemeColorType.ACCENT_4, 0.1)); | |
// Apply style | |
c.setStyle(s); | |
// Put a value | |
c.putValue("Testing"); | |
// Save the excel file | |
workbook.save(dataDir + "UseThemeColors.xlsx"); |
