Public API Changes

getBubbleSizeScale and setBubbleSizeScale methods have been added to IChartSeries and IChartSeriesGroup


getBubbleSizeScale specifies the scale factor for the bubble chart (can be between 0 and 300 percents of the default size). This is the getter not only of this series but of all series of parent series group - this is projection of appropriate group property. Use getParentSeriesGroup for access to parent series group. Use ParentSeriesGroup getBubbleSizeScale and setBubbleSizeScale methods for access to value.


Specifies the scale factor for the bubble chart (can be between 0 and 300 percents of the default size).

Presentation pres = new Presentation();
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Bubble, 100, 100, 400, 300);
}finally {

getShowDataLabelsOverMaximum and setShowDataLabelsOverMaximum methods have been added to IChart

getShowDataLabelsOverMaximum and setShowDataLabelsOverMaximum methods have been added to IChart

The methods specify whether to show the data labels when the value is greater than the maximum value on the value axis.

Presentation presentation = new Presentation();
    ISlide slide = presentation.getSlides().get_Item(0);
    IChart chart = slide.getShapes().addChart(ChartType.ScatterWithMarkers, 20, 100, 600, 400);
    chart.setShowDataLabelsOverMaximum(false);"output.pptx", SaveFormat.Pptx);
}finally {

You can use Aspose.Slides for Java with any BouncyCastle Provider

We have rewritten our algorithms, so now Aspose.Slides.Java API can be called safely without any dependency from Bouncy Castle library.

But for future versions we added the option of using Bouncy Castle as a crypto provider for working with X509 certificates and SignedCms. Because any reference to Bouncy Castle does not affect to Aspose.Slides for Java API now, you can but don’t required to:

a) Use Bouncy Castle cryptography APIs. You should add following reference:

Provider -


Add BouncyCastleProvider to java security:

Security.addProvider(new BouncyCastleProvider());

b) Use FIPS version of Bouncy Castle cryptography APIs. You should add following reference:

Provider -


Add BouncyCastleFipsProvider to java security:

Security.addProvider(new BouncyCastleFipsProvider());

c) Add both version of BC to classpath or do not add anything.

In a future we will report in a separate press release the fact that Aspose.Slides for Java required BouncyCastle again.
