Aspose.Words 19.7公共API的更改
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
? "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);
}暂时支持以下Markdown功能:
增加了新的公开枚举:
LoadFormat.Markdown SaveFormat.Markdown FileFormat.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。引号是样式名称中带有“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:如何使用块引号生成以下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");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);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");
}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 link textBox.BreakForwardLink(); // Break a forward link by setting a null textBox.Next = null; // Break a link, which leads to this textbox if (textBox.Previous != null) textBox.Previous.BreakForwardLink();
