隨著.NET版Aspose.Words for .Net v21.3的發(fā)布，Java版也隨之更新，除了一些通用功能外，也獨有新改善。

Aspose.Words for Java是一種高級Java Word處理API，使您可以直接在Java應(yīng)用程序中執(zhí)行各種文檔處理任務(wù)，無需Microsoft Word即可生成，修改和轉(zhuǎn)換文檔。

主要特點如下：

• 介紹了StyleCollection類的ClearQuickStyleGallery方法。
• 擴展字體API，用于設(shè)置文本的Fill屬性。
• 添加了使用StructuredDocumentTag范圍的子節(jié)點的功能。
• 修復(fù)了由于合并了隱藏的段落而導(dǎo)致嵌套的PDF書簽的問題。
• LINQ Reporting Engine支持的Select和SelectMany擴展方法。

新功能解析

①WORDSNET-7788：擴展字體API設(shè)置文本的Fill屬性

現(xiàn)在，不僅可以從ShapeBase中訪問Fill屬性，還可以從Font對象中訪問該屬性：

此外，以下新的公共屬性已添加到Fill類中：

此外，以下新的公共枚舉已添加到Aspose.Words.Drawing命名空間中：

用例如下：

// Open some document with text effects.
const string myDir = @"example\";
Document doc = new Document(myDir + "TextTwoColorGradient.docx");
 
// Get Fill object for Font of the first Run.
Fill fill = doc.FirstSection.Body.FirstParagraph.Runs[0].Font.Fill;
 
// Check Fill properties of the Font.
Console.WriteLine("The type of the fill is: {0}", fill.FillType);
Console.WriteLine("It is{0} visible.", fill.Visible ? "" : " not");
Console.WriteLine("The foreground color of the fill is: {0}", fill.ForeColor);
Console.WriteLine("The background color of the fill is: {0}", fill.BackColor);
Console.WriteLine("The fill is transparent at {0}%", fill.Transparency * 100);
Console.WriteLine("Note the opacity is opposite to transparency and has value: {0}%", fill.Opacity * 100);
 
// You can change, for example, the foreground color.
fill.ForeColor = Color.Yellow;
// Or even make it invisible.
fill.Visible = false;
// But let's make it visible again with foreground color Red.
fill.ForeColor = Color.Green;
// Note, it now has Solid type with 100% opacity.
Console.WriteLine("\nThe fill is changed:");
Console.WriteLine("The type of the fill is: {0}", fill.FillType);
Console.WriteLine("The foreground color of the fill is: {0}", fill.ForeColor);
Console.WriteLine("The fill opacity is {0}%", fill.Opacity * 100);
 
// Let's also change the transparency.
fill.Transparency = 0.25;
Console.WriteLine("\nThe fill is changed once again:");
Console.WriteLine("The fill transparency is {0}%", fill.Transparency * 100);
 
doc.Save(myDir + "TextTwoColorGradient Out.docx");
/*
This code example produces the following results:
 
The type of the fill is: Gradient
It is visible.
The foreground color of the fill is: Color [A=255, R=128, G=0, B=0]
The background color of the fill is: Color [A=255, R=0, G=0, B=0]
The fill is transparent at 16%
Note the opacity is opposite to transparency and has value: 84%
 
The fill is changed:
The type of the fill is: Solid
The foreground color of the fill is: Color [A=255, R=0, G=128, B=0]
The fill opacity is 100%
 
The fill is changed once again:
The fill transparency is 25%
*/

②WORDSNET-21189：添加了使用StructuredDocumentTagRangeStart的子節(jié)點的功能

以下公共屬性已添加到StructuredDocumentTagRangeStart類：

以下公共方法已添加到StructuredDocumentTagRangeStart類中：

這些更改允許枚舉范圍化結(jié)構(gòu)化文檔標(biāo)簽的子節(jié)點。為了客戶方便，功能遵循CompositeNode模式并返回實時集合。

用例：說明如何使用StructuredDocumentTagRangeStart的子節(jié)點

Document doc = new Document("document-containing-ranged-structured-document-tag");
StructuredDocumentTagRangeStart tag = (StructuredDocumentTagRangeStart)doc.FirstSection.Body.FirstChild;
 
Console.WriteLine(tag.ChildNodes.Count);
 
foreach(Node node in tag.ChildNodes)
    Console.WriteLine(node.NodeType);
 
foreach(Node node in tag.GetChildNodes(NodeType.Run, true))
    Console.WriteLine(node.GetText());

③WORDSNET-12810：為字體來源添加了警告回調(diào)屬性

以下公共屬性已添加到FontSourceBase類：

用例：

FontSettings settings = new FontSettings();
settings.SetFontsFolder("bad folder?", false);
 
FontSourceBase source = settings.GetFontsSources()[0];
IWarningCallback wc = new CustomWarningCallback();
source.WarningCallback = wc;
 
IListfontInfos = source.GetAvailableFonts();
 
Console.WriteLine((wc as IList)[0].Description);

輸出如下：

Error loading font from the folder "bad folder?": Illegal characters in path.
