Aspose.Slides for Java 14.6.0 中的公共 API 及不兼容的更改

此页面列出了 Aspose.Slides for Java 14.6.0 API 中所有 添加的 类、方法、属性等，任何新限制和引入的其他更改。

公共 API 更改

新增类、方法、接口和枚举

新增 ViewType 枚举、IViewProperties 接口、ViewProperties 类和 IPresentation.getViewProperties() 方法

IPresentation.getViewProperty() 方法提供对 IViewProperties 的访问，并允许您在 Microsoft PowerPoint 中打开演示文稿时更改演示文稿视图类型和备注可见性。

 Presentation p = new Presentation();

p.getViewProperties().setLastView(ViewType.SlideMasterView);

新增 Aspose.Slides.IShapeCollection.addClone(…) 和 .insertClone(…) 方法

这些方法

• Aspose.Slides.IShapeCollection.addClone(IShape sourceShape),
• Aspose.Slides.IShapeCollection.addClone(IShape sourceShape, float x, float y),
• Aspose.Slides.IShapeCollection.addClone(IShape sourceShape, float x, float y, float width, float height),
• Aspose.Slides.IShapeCollection.insertClone(int index, IShape sourceShape),
• Aspose.Slides.IShapeCollection.insertClone(int index, IShape sourceShape, float x, float y)，以及
• Aspose.Slides.IShapeCollection.insertClone(int index, IShape sourceShape, float x, float y, float width, float height)

将指定形状的副本添加到/插入集合中。

 Presentation srcPres = new Presentation("data/Source Frame.pptx");

IShapeCollection sourceShapes = srcPres.getSlides().get_Item(0).getShapes();

ILayoutSlide blankLayout = srcPres.getMasters().get_Item(0).getLayoutSlides().getByType(SlideLayoutType.Blank);

ISlide destSlide = srcPres.getSlides().addEmptySlide(blankLayout);

IShapeCollection destShapes = destSlide.getShapes();

destShapes.addClone(sourceShapes.get_Item(1), 50, 150 + sourceShapes.get_Item(0).getHeight());

destShapes.addClone(sourceShapes.get_Item(2));

destShapes.addClone(sourceShapes.get_Item(3), 50, 200, 50, 50);

destShapes.addClone(sourceShapes.get_Item(4));

destShapes.addClone(sourceShapes.get_Item(5), 300, 300, 50, 200);

destShapes.insertClone(0, sourceShapes.get_Item(0), 50, 150);

新增 Aspose.Slides.Charts.IDataSourceTypeForErrorBarsCustomValues 接口

该接口指定 ChartDataPoint.ErrorBarsCustomValues 属性列表中的值类型。

 Presentation pres = new Presentation();

IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Bubble, 50, 50, 400, 300, true);

IChartSeries series = chart.getChartData().getSeries().get_Item(0);

IErrorBarsFormat errBarX = series.getErrorBarsXFormat();

IErrorBarsFormat errBarY = series.getErrorBarsYFormat();

errBarX.setVisible(true);

errBarY.setVisible(true);

errBarX.setValueType(ErrorBarValueType.Custom);

errBarY.setValueType(ErrorBarValueType.Custom);

IChartDataPointCollection points = series.getDataPoints();

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForXPlusValues(DataSourceType.DoubleLiterals);

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForXMinusValues(DataSourceType.DoubleLiterals);

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForYPlusValues(DataSourceType.DoubleLiterals);

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForYMinusValues(DataSourceType.DoubleLiterals);

for (int i = 0; i < points.size(); i++)

{

    points.get_Item(i).getErrorBarsCustomValues().getXMinus().setAsLiteralDouble(i + 1);

    points.get_Item(i).getErrorBarsCustomValues().getXPlus().setAsLiteralDouble(i + 1);

    points.get_Item(i).getErrorBarsCustomValues().getYMinus().setAsLiteralDouble(i + 1);

    points.get_Item(i).getErrorBarsCustomValues().getYPlus().setAsLiteralDouble(i + 1);

}

pres.save("data/ErrorBarsCustomValues.pptx", SaveFormat.Pptx);

新增 Aspose.Slides.Charts.IErrorBarsCustomValues 接口

当 IErrorBarsFormat.ValueType 属性等于 Custom 时，使用系列的 DataPoints 集合中特定数据点的 ErrorBarCustomValues 属性来指定值。

 Presentation pres = new Presentation();

IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Bubble, 50, 50, 400, 300, true);

IChartSeries series = chart.getChartData().getSeries().get_Item(0);

IErrorBarsFormat errBarX = series.getErrorBarsXFormat();

IErrorBarsFormat errBarY = series.getErrorBarsYFormat();

errBarX.setVisible(true);

errBarY.setVisible(true);

errBarX.setValueType(ErrorBarValueType.Custom);

errBarY.setValueType(ErrorBarValueType.Custom);

IChartDataPointCollection points = series.getDataPoints();

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForXPlusValues(DataSourceType.DoubleLiterals);

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForXMinusValues(DataSourceType.DoubleLiterals);

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForYPlusValues(DataSourceType.DoubleLiterals);

points.getDataSourceTypeForErrorBarsCustomValues().setDataSourceTypeForYMinusValues(DataSourceType.DoubleLiterals);

for (int i = 0; i < points.size(); i++)

{

    points.get_Item(i).getErrorBarsCustomValues().getXMinus().setAsLiteralDouble(i + 1);

    points.get_Item(i).getErrorBarsCustomValues().getXPlus().setAsLiteralDouble(i + 1);

    points.get_Item(i).getErrorBarsCustomValues().getYMinus().setAsLiteralDouble(i + 1);

    points.get_Item(i).getErrorBarsCustomValues().getYPlus().setAsLiteralDouble(i + 1);

}

pres.save("data/ErrorBarsCustomValues.pptx", SaveFormat.Pptx);

新增 Aspose.Slides.Charts.IErrorBarsFormat 接口

该接口表示图表系列的误差线。 在自定义值类型的情况下，使用系列的 DataPoins 集合中特定数据点的 ErrorBarCustomValues 属性来指定值。

 Presentation pres = new Presentation();

IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Bubble, 50, 50, 400, 300, true);

IErrorBarsFormat errBarX = chart.getChartData().getSeries().get_Item(0).getErrorBarsXFormat();

IErrorBarsFormat errBarY = chart.getChartData().getSeries().get_Item(0).getErrorBarsYFormat();

errBarX.setVisible(true);

errBarY.setVisible(true);

errBarX.setValueType(ErrorBarValueType.Fixed);

errBarX.setValue(0.1f);

errBarY.setValueType(ErrorBarValueType.Percentage);

errBarY.setValue(5);

errBarX.setType(ErrorBarType.Plus);

errBarY.getFormat().getLine().setWidth(2);

errBarX.setEndCap(true);

pres.save("data/ErrorBars.pptx", SaveFormat.Pptx);
