Aspose.Words 19.7公共API的更改
▲添加了属性Revision.Group
在Revision类中添加了以下新属性:
////// Gets the revision group. Returns null if the revision does not belong to any group.///////// Revision has no group if revision type is RevisionType.StyleDefinitionChange or/// if the revision is not longer exist in document context (accepted/rejected).///public RevisionGroup Group
使用案例:
Document doc = new Document(@"source.docx"); foreach (Revision revision in doc.Revisions){ string groupText = revision.Group != null nbsp;"Revision group text: " + revision.Group.Text : "Revision has no group"; Console.WriteLine("Type: " + revision.RevisionType); Console.WriteLine("Author: " + revision.Author); Console.WriteLine("Date: " + revision.DateTime); Console.WriteLine("Revision text: " + revision.ParentNode.ToString(SaveFormat.Text)); Console.WriteLine(groupText);}
▲为Markdown功能实现了基本的读写器
暂时支持以下Markdown功能:
- 标题
- 成批引用
- 横向规则
- 黑体强调
- 斜体强调
增加了新的公开枚举:
LoadFormat.MarkdownSaveFormat.MarkdownFileFormat.Markdown
添加了新的TxtSaveOptionsBase类:
////// The base class for specifying additional options when saving a document into a text based formats.///public abstract class TxtSaveOptionsBase : SaveOptions
一些成员从TxtSaveOptions类移动到TxtSaveOptionsBase类:
////// Specifies the encoding to use when exporting in text formats. /// Default value isEncoding.UTF8'UTF-8' Charset.///public Encoding Encoding ////// Specifies the string to use as a paragraph break when exporting in text formats./////////The default value is.///public string ParagraphBreak ////// Specifies whether the program should attempt to preserve layout of tables when saving in the plain text format./// The default value is false.///public bool PreserveTableLayout //////Allows to specify whether the page breaks should be preserved during export.///The default value is false.///////// The property affects only page breaks that are inserted explicitly into a document. /// It is not related to page breaks that MS Word automatically inserts at the end of each page.///public bool ForcePageBreaks ////// Specifies the way headers and footers are exported to the text formats./// Default value is.///public TxtExportHeadersFootersMode ExportHeadersFootersMode
功能的实现主要遵循CommonMark规范。在AW模型中,Markdown功能表示为相应的样式或直接格式。因此,粗体和斜体表示为Font.Bold和Font.Italic。标题是标题1 – 标题6样式的段落。引 是样式名称中带有“引用”的段落。HorizontalRule是具有HorizontalRule形状的段落。
使用案例1:如何生成以下Markdown文档的重点:
Markdown treats asterisks (*) and underscores (_) as indicators of emphasis. You can write **bold** or *italic* text. You can also write ***BoldItalic***text.
DocumentBuilder builder = new DocumentBuilder(new Document());builder.Writeln("Markdown treats asterisks (*) and underscores (_) as indicators of emphasis.");builder.Write("You can write ");builder.Font.Bold = true;builder.Write("bold");builder.Font.Bold = false;builder.Write(" or ");builder.Font.Italic = true;builder.Write("italic");builder.Font.Italic = false;builder.Writeln(" text. ");builder.Write("You can also write ");builder.Font.Bold = true;builder.Font.Italic = true;builder.Write("BoldItalic");builder.Font.Bold = false;builder.Font.Italic = false;builder.Write("text."); builder.Document.Save("EmphasesExample.md");
使用案例2:如何使用标题生成以下Markdown文档:
The following produces headings:# Heading1## Heading2### Heading3#### Heading4##### Heading5###### Heading6# **Bold Heading1**
Document doc = new Document();DocumentBuilder builder = new DocumentBuilder(doc); // By default Heading styles in Word may have bold and italic formatting.// If we do not want text to be emphasized, set these properties explicitly to false.builder.Font.Bold = false;builder.Font.Italic = false; builder.Writeln("The following produces headings:");builder.ParagraphFormat.Style = doc.Styles["Heading 1"];builder.Writeln("Heading1");builder.ParagraphFormat.Style = doc.Styles["Heading 2"];builder.Writeln("Heading2");builder.ParagraphFormat.Style = doc.Styles["Heading 3"];builder.Writeln("Heading3");builder.ParagraphFormat.Style = doc.Styles["Heading 4"];builder.Writeln("Heading4");builder.ParagraphFormat.Style = doc.Styles["Heading 5"];builder.Writeln("Heading5");builder.ParagraphFormat.Style = doc.Styles["Heading 6"];builder.Writeln("Heading6"); // Note, emphases are also allowed inside Headings:builder.Font.Bold = true;builder.ParagraphFormat.Style = doc.Styles["Heading 1"];builder.Writeln("Bold Heading1"); doc.Save("HeadingsExample.md");
使用案例3:如何使用块引 生成以下Markdown文档:
We support blockquotes in Markdown:>*Lorem*>*ipsum* The quotes can be of any level and can be nested:>>>Quote level 3>>>>Nested quote level 4>>*Back to first level*> ### Headings are allowed inside Quotes
Document doc = new Document();DocumentBuilder builder = new DocumentBuilder(doc); builder.Writeln("We support blockquotes in Markdown:");builder.ParagraphFormat.Style = doc.Styles["Quote"];builder.Writeln("Lorem");builder.Writeln("ipsum");builder.ParagraphFormat.Style = doc.Styles["Normal"];builder.Writeln("The quotes can be of any level and can be nested:");Style quoteLevel3 = doc.Styles.Add(StyleType.Paragraph, "Quote2");builder.ParagraphFormat.Style = quoteLevel3;builder.Writeln("Quote level 3");Style quoteLevel4 = doc.Styles.Add(StyleType.Paragraph, "Quote3");builder.ParagraphFormat.Style = quoteLevel4;builder.Writeln("Nested quote level 4");builder.ParagraphFormat.Style = doc.Styles["Quote"];builder.Writeln();builder.Writeln("Back to first level");Style quoteLevel1WithHeading = doc.Styles.Add(StyleType.Paragraph, "Quote Heading 3");builder.ParagraphFormat.Style = quoteLevel1WithHeading;builder.Write("Headings are allowed inside Quotes"); doc.Save("QuotesExample.md");
使用案例4:如何使用水平规则生成以下Markdown文档:
We support Horizontal rules (Thematic breaks) in Markdown: -----
DocumentBuilder builder = new DocumentBuilder(new Document()); builder.Writeln("We support Horizontal rules (Thematic breaks) in Markdown:");builder.InsertHorizontalRule(); builder.Document.Save("HorizontalRuleExample.md");
使用案例5:如何阅读Markdown文档:
// This is Markdown document that was produced in example of UC3.Document doc = new Document("QuotesExample.md"); // Let's remove Heading formatting from a Quote in the very last paragraph.Paragraph paragraph = doc.FirstSection.Body.LastParagraph;paragraph.ParagraphFormat.Style = doc.Styles["Quote"]; doc.Save("QuotesModifiedExample.md");
▲实现了检测SmartArt形状的功能
将以下新属性添加到Shape类:
////// Returns true if this Shape has a SmartArt object.///public bool HasSmartArt
使用案例:在文档中使用SmartArt计算多个形状。
Document doc = new Document(@"input.docx"); int count = 0;foreach (Shape shape in doc.GetChildNodes(NodeType.Shape, true)){ if (shape.HasSmartArt) count++;} Console.WriteLine("The document has {0} shapes with SmartArt.", count);
▲实现了对OpenType字体的支持和对Kerning功能的支持
新的公共属性TextShaperFactory已添加到LayoutOptions类。
public ITextShaperFactory TextShaperFactory { get; set; }
应通过单独的nuget-packages提供ITextShaperFactory的实现。具体实现应创建一个表示字体的文本整形器,并计算文本的整形信息。下面是一个用法示例:
public void Test(){ // Open a document Document doc = new Document("OpenType.Document.docx"); // When text shaper factory is set, layout starts to use OpenType features. // An Instance property returns static BasicTextShaperCache object wrapping HarfBuzzTextShaperFactory doc.LayoutOptions.TextShaperFactory = Aspose.Words.Shaping.HarfBuzz.HarfBuzzTextShaperFactory.Instance; // Render the document to PDF format doc.Save("OpenType.Document.pdf");}
▲WORDSNET-11297 – 实现了用于处理链接文本框的公共API
添加了一个用于从文本框中获取父形状的公共属性,以允许客户从链接的TextBox中查找链接的Shape。
////// Determines whether this TextBox can be linked to the target Textbox.///public bool IsValidLinkTarget(TextBox target){} ////// Returns or sets a TextBox that represents the next TextBox in a sequence of shapes.///public TextBox Next{ get; set;} ////// Returns a TextBox that represents the previous TextBox in a sequence of shapes.///public TextBox Previous{ get;} ////// Breaks the forward link for the specified TextBox, if such a link exists.///////// BreakForwardLink() doesn't break all other links in the current sequence of shapes./// For example: 1-2-3-4 sequence and BreakForwardLink at the 2-nd textbox will create/// two sequences 1-2, 3-4.///public void BreakForwardLink(){} ////// Gets a parent shape for the TextBox.///public Shape Parent{ get { return mParent; }}
使用案例:创建从shape1.TextBox到shape2.TextBox的链接。
TextBox textBox1 = shape1.TextBox;TextBox textBox2 = shape2.TextBox; if (textBox1.IsValidLinkTarget(textBox2)) textBox1.Next = textBox2;
使用案例:检查shape.TextBox是序列的头部,尾部还是中间。
TextBox textBox = shape.TextBox; if ((textBox.Next != null) && (textBox.Previous == null)){ //The head of the sequence.} if ((textBox.Next != null) && (textBox.Previous != null)){ //The Middle of the sequence.} if ((textBox.Next == null) && (textBox.Previous != null)){ //The Tail of the sequence.}
使用案例:破坏shape.TextBox的链接。
TextBox textBox = shape.TextBox; // Break a forward linktextBox.BreakForwardLink(); // Break a forward link by setting a nulltextBox.Next = null; // Break a link, which leads to this textboxif (textBox.Previous != null) textBox.Previous.BreakForwardLink();
