}制作 PDF 文档时，如果我们只使用黑色字体，有时会让文章变得单调乏味。我们可以为不同的文字设置不同的字体颜色，使制作的文档更美观、更生动，增强文档对读者的吸引力。本文将介绍如何使用 Spire.PDF for Java 通过代码设置 PDF 文档中文字的字体颜色。
首先，您需要在 Java 程序中添加 Spire.Pdf.jar 文件作为依赖项。JAR 文件可以从此链接下载。如果您使用 Maven，则可以将以下代码添加到项目的 pom.xml 文件中，从而在应用程序中导入 JAR 文件。

Spire.PDF for Java 提供了 PdfSolidBrush 类以设置文本的绘制颜色，支持以特定的 RGB 值或 HTML 颜色代码来定义绘制颜色。详细操作步骤如下：
import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.graphics.PdfRGBColor;
import com.spire.pdf.graphics.PdfSolidBrush;
import com.spire.pdf.graphics.PdfTrueTypeFont;
import java.awt.*;
public class setFontColor {
public static void main(String[] args) {
//创建 PdfDocument 类的对象
PdfDocument doc = new PdfDocument();
//添加一个页面
PdfPageBase page = doc.getPages().add();
//设置位置
float y = 30;
//创建 PdfSolidBrush 类的对象并设置颜色
PdfRGBColor rgb1 = new PdfRGBColor(Color.green);
PdfSolidBrush brush1 = new PdfSolidBrush(rgb1);
//以RGB值设置颜色
PdfRGBColor rgb2 = new PdfRGBColor(0,197,205);
PdfSolidBrush brush2 = new PdfSolidBrush(rgb2);
//以HTML代码设置颜色
Color color = Color.decode("#A52A2A");
PdfSolidBrush brush3 = new PdfSolidBrush(new PdfRGBColor(color));
//创建 PdfTrueTypeFont 类的对象
Font font = new Font("华文中宋", java.awt.Font.BOLD, 14);
PdfTrueTypeFont trueTypeFont = new PdfTrueTypeFont(font);
//绘制文本
page.getCanvas().drawString("设置绘制颜色", trueTypeFont, brush1, 0, (y = y + 30f));

Excel 中，我们可以通过调整数据列顺序来实现将批量数据进行布局调整，以达到表格设计美观性或者表格数据设计得严谨性等目的。本文，将通过使用 Spire.XLS for Java 来实现如何调整列顺序。以下是具体步骤及方法。
首先，您需要在 Java 程序中添加 Spire.XLS for Java 文件作为依赖项。JAR 文件可以从此链接下载。如果您使用 Maven，则可以将以下代码添加到项目的 pom.xml 文件中，从而轻松地在应用程序中导入 JAR 文件。
<repositories>
<repository>
<id>com.e-iceblue</id>
<name>e-iceblue</name>
<url>https://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.xls</artifactId>
<version>15.11.3</version>
</dependency>
</dependencies>
以下是调整列顺序的主要代码步骤：
import com.spire.xls.*;
public class ChangeColumnOrder {
public static void main(String[] args) {
//创建Workbook类的对象
Workbook workbook = new Workbook();
//加载Excel文件
workbook.loadFromFile( "test.xlsx");
//获取第一个工作表
Worksheet worksheet = workbook.getWorksheets().get(0);
//设置新的列顺序
int[] newColumnOrder = new int[]{3, 0, 1, 5, 7, 4,2,8,6};
//添加一个临时工作表
Worksheet newSheet = workbook.getWorksheets().add("temp");
//将数据从第一个工作表复制到临时工作表
newSheet.copyFrom(worksheet);
//循环遍历newColumnOrder数组
for (int i = 0; i < newColumnOrder.length; i++) {
//从临时工作表复制列到第一个工作表
newSheet.getColumns()[newColumnOrder[i]].copy(worksheet.getColumns()[i],true,true);
//将第一个工作表的某一列的宽度设置为临时工作表的宽度
worksheet.getColumns()[i].setColumnWidth(newSheet.getColumns()[newColumnOrder[i]].getColumnWidth());
}
//删除临时表格
workbook.getWorksheets().remove(newSheet);
//将工作簿另存为文件
workbook.saveToFile("ChangeColumnOrder.xlsx", FileFormat.Version2010);
}
}

XPS（XML Paper Specification）是一种固定布局的文档格式，旨在保持文档的保真度并提供与设备无关的文档外观。XPS 类似于 PDF，但 XPS 基于 XML 而不是 PostScript。如果想要将 Word 文档保存为固定布局的文件格式，XPS 是个不错的选择。本文将介绍如何使用 Spire. Doc for .NET 通过代码将 Word 文档转换为 XPS 文件。
首先，您需要将 Spire.Doc for.NET 包含的 DLL 文件作为引用添加到您的 .NET 项目中。DLL 文件可以从此链接下载，也可以通过 NuGet 安装。
PM> Install-Package Spire.Doc使用 Spire.Doc for .NET 将 Word 文档转换为 XPS 文件只需载入 Word 文档后保存为 XPS 格式文件即可，详细操作步骤如下：
using Spire.Doc;
namespace ConvertWordToXps
{
class Program
{
static void Main(string[] args)
{
//创建 Document 类的对象
Document doc = new Document();
//载入Word文档
doc.LoadFromFile(@"C:\示例.docx");
//将文档保存为XPS文件
doc.SaveToFile("Word转XPS.xps", FileFormat.XPS);
}
}
}Imports Spire.Doc
Namespace ConvertWordToXps
Class Program
Shared Sub Main(ByVal args() As String)
'创建 Document 类的对象
Dim doc As Document = New Document()
'载入Word文档
doc.LoadFromFile("https://cdn.e-iceblue.cn/C:\示例.docx")
'将文档保存为XPS文件
doc.SaveToFile("Word转XPS.xps", FileFormat.XPS)
End Sub
End Class
End Namespace
