公共 API 更改
Enum OrganizationChartLayoutType 已添加
Aspose.Slides.SmartArt.OrganizationChartLayoutType 枚举表示组织结构图中子节点的格式类型。
Method IBulletFormat.ApplyDefaultParagraphIndentsShifts 已添加
Aspose.Slides.IBulletFormat.ApplyDefaultParagraphIndentsShifts 方法在启用项目符号时（如 PowerPoint 在启用段落项目符号/编号时的行为），为有效段落的缩进和左边距设置默认的非零偏移。若禁用项目符号，则仅重置段落的缩进和左边距（如 PowerPoint 在禁用段落项目符号/编号时的行为）。
请参阅示例此处：
Method IConnector.Reroute 已添加
Aspose.Slides.IConnector.Reroute 方法重新路由连接线，使其在连接的形状之间采取最短路径。为此，Reroute() 方法可能会更改 StartShapeConnectionSiteIndex 和 EndShapeConnectionSiteIndex。
using(Presentation input = new Presentation())
{
IShapeCollection shapes = input.Slides[0].Shapes;
IConnector connector = shapes.AddConnector(ShapeType.BentConnector2, 0, 0, 10, 10);
IAutoShape ellipse = shapes.AddAutoShape(ShapeType.Ellipse, 0, 100, 100, 100);
IAutoShape rectangle = shapes.AddAutoShape(ShapeType.Rectangle, 100, 300, 100, 100);
connector.StartShapeConnectedTo = ellipse;
connector.EndShapeConnectedTo = rectangle;
connector.Reroute();
input.Save("output.pptx", SaveFormat.Pptx);
}
Method IPresentation.GetSlideById 已添加
Aspose.Slides.IPresentation.GetSlideById(System.UInt32) 方法根据幻灯片 ID 返回 Slide、MasterSlide 或 LayoutSlide。
using (Presentation presentation = new Presentation())
{
uint id = presentation.Slides[0].SlideId;
IBaseSlide slide = presentation.GetSlideById(id);
Debug.Assert(presentation.Slides[0] == slide);
}
Property IShape.ConnectionSiteCount 已添加
Aspose.Slides.IShape.ConnectionSiteCount 属性返回形状上的连接点数量。
using(Presentation input = new Presentation())
{
IShapeCollection shapes = input.Slides[0].Shapes;
IConnector connector = shapes.AddConnector(ShapeType.BentConnector2, 0, 0, 10, 10);
IAutoShape ellipse = shapes.AddAutoShape(ShapeType.Ellipse, 0, 100, 100, 100);
IAutoShape rectangle = shapes.AddAutoShape(ShapeType.Rectangle, 100, 200, 100, 100);
connector.StartShapeConnectedTo = ellipse;
connector.EndShapeConnectedTo = rectangle;
uint wantedIndex = 6;
if (ellipse.ConnectionSiteCount > wantedIndex)
{
connector.StartShapeConnectionSiteIndex = wantedIndex;
}
input.Save("output.pptx", SaveFormat.Pptx);
}
Property ISmartArt.IsReversed 已添加
Aspose.Slides.SmartArt.ISmartArt.IsReversed 属性用于获取或设置 SmartArt 图表相对于左到右 (LTR) 或右到左 (RTL) 的状态（前提是图表支持翻转）。
using (Presentation pres = new Presentation())
{
ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicProcess);
smart.IsReversed = true;
pres.Save("out.pptx", Export.SaveFormat.Pptx);
}
Property ISmartArt.Nodes 已添加
Aspose.Slides.SmartArt.ISmartArt.Nodes 属性返回 SmartArt 对象中根节点的集合。
using (Presentation pres = new Presentation())
{
ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.VerticalBulletList);
ISmartArtNode node = smart.Nodes[1]; // select second root node
node.TextFrame.Text = "Second root node";
pres.Save("out.pptx", Export.SaveFormat.Pptx);
}
Property ISmartArtNode.IsHidden 已添加
Aspose.Slides.SmartArt.ISmartArtNode.IsHidden 属性如果该节点在数据模型中是隐藏节点，则返回 true。
using (Presentation pres = new Presentation())
{
ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.RadialCycle);
ISmartArtNode node = smart.AllNodes.AddNode();
bool hidden = node.IsHidden; //returns true
if(hidden)
{
//do some actions or notifications
}
pres.Save("out.pptx", Export.SaveFormat.Pptx);
}
Property ISmartArtNode.OrganizationChartLayout 已添加
Aspose.Slides.SmartArt.ISmartArtNode.OrganizationChartLayout 属性用于获取或设置与当前节点关联的组织结构图类型。
using (Presentation pres = new Presentation())
{
ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.OrganizationChart);
smart.Nodes[0].OrganizationChartLayout = OrganizationChartLayoutType.LeftHanging;
pres.Save("out.pptx", Export.SaveFormat.Pptx);
}
Set Method for Property ISmartArt.Layout 已添加
Aspose.Slides.SmartArt.ISmartArt.Layout 属性的 set 方法已添加。它允许更改现有图表的布局类型。
using (Presentation pres = new Presentation())
{
ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicBlockList);
smart.Layout = SmartArtLayoutType.BasicProcess;
pres.Save("out.pptx", Export.SaveFormat.Pptx);
}
