我们很高兴地宣布 Spire.Doc 14.9.1 版本正式发布。该版本新增强大的 Word 文档主题管理功能，同时优化图表样式与文档导出的字体嵌入相关配置。开发者现在可通过代码完整自定义、复制和编辑 Word 文档主题，统一多份文件的视觉风格。

此外，两项影响文档转换与页面删除的关键漏洞已完成修复，有效提升整体文档处理稳定性。详细更新内容如下。

新功能:

• 支持创建自定义文档主题

// Create a new document and apply the theme
Document doc = new Document();

// Configure a custom theme
Theme theme = doc.Theme;
theme.MajorFonts.Latin = "Courier New";  // Set the heading font to Courier New
theme.MinorFonts.Latin = "Agency FB";    // Set the body font to Agency FB

ThemeColors colors = theme.Colors;
colors.Dark1 = Color.MidnightBlue;
colors.Light1 = Color.PaleGreen;
colors.Dark2 = Color.Indigo;
colors.Light2 = Color.Khaki;
colors.Accent1 = Color.OrangeRed;
colors.Accent2 = Color.LightSalmon;
colors.Accent3 = Color.Yellow;
colors.Accent4 = Color.Gold;
colors.Accent5 = Color.BlueViolet;
colors.Accent6 = Color.DarkViolet;
colors.Hyperlink = Color.Black;
colors.FollowedHyperlink = Color.Gray;

Section section = doc.AddSection();

// Create a heading and apply MajorFonts and the Accent1 color
Paragraph heading = section.AddParagraph();
heading.AppendText("Document Theme Test");
heading.ApplyStyle(BuiltinStyle.Heading1);

// Link the heading style to MajorFonts
ParagraphStyle heading1Style = (ParagraphStyle)doc.Styles["Heading 1"];
heading1Style.CharacterFormat.ThemeFont = ThemeFont.Major;  // Use the Major theme font (heading font)
heading1Style.CharacterFormat.ThemeColor = ThemeColor.Accent1; // Use the Accent1 theme color

// Create a body paragraph and apply MinorFonts
Paragraph body = section.AddParagraph();
body.AppendText("This document uses a custom theme created programmatically.");

// Link the Normal style to MinorFonts
ParagraphStyle normalStyle = (ParagraphStyle)doc.Styles["Normal"];
normalStyle.CharacterFormat.ThemeFont = ThemeFont.Minor;  // Use the Minor theme font (body font)
normalStyle.CharacterFormat.ThemeColor = ThemeColor.Text1; // Use the default text color
                                                           // Add a test paragraph to verify the theme color
Paragraph colorTest = section.AddParagraph();
TextRange textRange = colorTest.AppendText("Accent1 Color Test");
textRange.CharacterFormat.ThemeColor = ThemeColor.Accent1; // Use the Accent1 theme color directly

doc.SaveToFile(outputFile, FileFormat.Docx);
doc.Close();

• 支持将现有文档的主题复制至其他文档

// Load the source document and get its theme
Document sourceDoc = new Document();
sourceDoc.LoadFromFile("Theme.docx");
Theme sourceTheme = sourceDoc.Theme;

// Create a destination document
Document newDoc = new Document();

// Copy the source document's theme (theme fonts and colors) to the destination document
sourceDoc.CloneThemesTo(newDoc);

newDoc.SaveToFile("CopyTheme.docx", FileFormat.Docx);

• 支持获取、修改文档主题。

Document doc = new Document();

// Set the font faces of the document theme
doc.Theme.MinorFonts.Latin = "Algerian";
doc.Theme.MinorFonts.EastAsian = "Aharoni";
doc.Theme.MinorFonts.ComplexScript = "Andalus";

// Set the theme font and theme color of the style's character format
CharacterFormat font = ((ParagraphStyle)doc.Styles["Normal"]).CharacterFormat;
font.ThemeFont = ThemeFont.Minor;
font.ThemeColor = ThemeColor.Accent2;

// Get the theme font and theme color
ThemeFont themeFont = font.ThemeFont;
string fontName = font.FontName;
Color textColor = font.TextColor;

doc.SaveToFile("ThemeAttributes.docx", FileFormat.Docx);

• 支持配置「仅嵌入文档所用字符」字体子集嵌入

doc.setEmbedFontsInFile(true);
doc.setSaveSubsetFonts(true);

• 支持设置图表及图表数据系列的填充样式。

// Create a document and add a column chart
Document doc = new Document();
Section section = doc.AddSection();
ShapeObject shape = section.AddParagraph().AppendChart(ChartType.Column, 500, 300);
Chart chart = shape.Chart;
chart.Series.Clear();
chart.Series.Add("Sales", new string[] { "Q1", "Q2", "Q3", "Q4" }, new double[] { 120, 90, 160, 200 });

// Chart area - solid fill
chart.Format.Fill.FillType = FillType.Solid;
chart.Format.Fill.Color = Color.OrangeRed;
chart.Format.Fill.Transparency = 0.3;

// Data points of the first series - linear gradient fill
Fill seriesFill = chart.Series[0].DataPoints.Format.Fill;
seriesFill.FillType = FillType.Shade;
seriesFill.GradientType = GradientFillType.Linear;
seriesFill.SetGradientDirection(GradientFillDirection.LinearUp);
seriesFill.GradientStops.Add(new GradientStop(0, Color.White));
seriesFill.GradientStops.Add(new GradientStop(1, Color.OrangeRed));

// Data labels - enable and use a solid fill
chart.Series[0].HasDataLabels = true;
chart.Series[0].DataLabels.Format.Fill.FillType = FillType.Solid;
chart.Series[0].DataLabels.Format.Fill.Color = Color.LightYellow;

doc.SaveToFile("ChartFill.docx", FileFormat.Docx);

// Create a document and add a line chart
Document doc = new Document();
Section section = doc.AddSection();
ShapeObject shape = section.AddParagraph().AppendChart(ChartType.Line, 500, 300);
Chart chart = shape.Chart;
chart.Series.Clear();
chart.Series.Add("Trend", new string[] { "Cat1", "Cat2", "Cat3", "Cat4" }, new double[] { 4.3, 2.4, 3.1, 5.2 });

// Chart area - border weight, dash style and solid color
chart.Format.Stroke.Weight = 2;
chart.Format.Stroke.DashStyle = DashStyle.Dash;
chart.Format.Stroke.Fill.FillType = FillType.Solid;
chart.Format.Stroke.Fill.Color = Color.Blue;

// Data series border - set through its data points
chart.Series[0].DataPoints.Format.Stroke.Fill.FillType = FillType.Solid;
chart.Series[0].DataPoints.Format.Stroke.Fill.Color = Color.Red;
chart.Series[0].DataPoints.Format.Stroke.Weight = 1.5;

// Start and end arrows on the axes
chart.AxisX.Format.Stroke.StartArrowType = ArrowType.Arrow;
chart.AxisX.Format.Stroke.EndArrowType = ArrowType.Arrow;
chart.AxisY.Format.Stroke.StartArrowType = ArrowType.Arrow;
chart.AxisY.Format.Stroke.EndArrowType = ArrowType.Arrow;

doc.SaveToFile("ChartStroke.docx", FileFormat.Docx);
