Public API Changes

ActualMaxValue, ActualMinValue, ActualMajorUnit, ActualMinorUnit, ActualMajorUnitScale, ActualMinorUnitScale have been added to Axis, IAxis

  • double ActualMaxValue         Gets actual maximum value on the axis.
  • double ActualMinValue         Gets actual minimum value on the axis.
  • double ActualMajorUnit         Gets actual major unit of the axis.
  • double ActualMinorUnit        Gets actual minor unit of the axis.
  • TimeUnitType ActualMajorUnitScale            Gets actual major unit scale of the axis.
  • TimeUnitType ActualMinorUnitScale            Gets actual minor unit scale of the axis.

Call method IChart.ValidateChartLayout() previously to get actual values for these properties.

using (Presentation pres = new Presentation())
{
     Chart chart = (Chart)pres.Slides[0].Shapes.AddChart(ChartType.Area, 100, 100, 500, 350);
     chart.ValidateChartLayout();

     double maxValue = chart.Axes.VerticalAxis.ActualMaxValue;
     double minValue = chart.Axes.VerticalAxis.ActualMinValue;

     double majorUnit = chart.Axes.HorizontalAxis.ActualMajorUnit;
     double minorUnit = chart.Axes.HorizontalAxis.ActualMinorUnit;
}

ActualX, ActualY, ActualWidth, ActualHeight have been added to IChartPlotArea, ChartPlotArea

float ActualX  Gets actual X location (left) of the chart element relative to the left top corner of the chart. Call method IChart.ValidateChartLayout() before to get actual values.

  • float ActualY  Gets actual top of the chart element relative to the left top corner of the chart. Call method IChart.ValidateChartLayout() before to get actual values.
  • float ActualWidth       Gets actual width of the chart element. Call method IChart.ValidateChartLayout() before to get actual values.
  • float ActualHeight      Gets actual height of the chart element. Call method IChart.ValidateChartLayout() before to get actual values.

Call method IChart.ValidateChartLayout() previously to get actual values for these properties.

using (Presentation pres = new Presentation())
{
     Chart chart = (Chart)pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 100, 100, 500, 350);
     chart.ValidateChartLayout();

     double x = chart.PlotArea.ActualX;
     double y = chart.PlotArea.ActualY;
     double w = chart.PlotArea.ActualWidth;
     double h = chart.PlotArea.ActualHeight;
}

DataSourceType and ExternalWorkbookPath properties has been added to IChartData interface and ChartData class

Two new properties have been added to IChartData interface and ChartData class:

DataSourceType of type ChartDataSourceType, which represents data source of the chart.

ExternalWorkbookPath of type string, which represents external workbook path if data source is external, null otherwise.

ChartDataSourceType is a new enum which represents the two values: InternalWorkbook and ExternalWorkbook.

Example:

using (Presentation pres = new Presentation("pres.pptx"))
{
     ISlide slide = pres.Slides[1];
     IChart chart = (IChart)slide.Shapes[0];
     ChartDataSourceType sourceType = chart.ChartData.DataSourceType;
     if (sourceType == ChartDataSourceType.ExternalWorkbook)
     {
         string path = chart.ChartData.ExternalWorkbookPath;
     }
}

IActualLayout interface has been added

Properties of IActualLayout provide information about actual position of parent chart element. It is necessary to call method IChart.ValidateChartLayout() previously to fill properties with actual values.

using (Presentation pres = new Presentation())
{
     Chart chart = (Chart)pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 100, 100, 500, 350);
     chart.ValidateChartLayout();

     double x = chart.PlotArea.ActualX;
     double y = chart.PlotArea.ActualY;
     double w = chart.PlotArea.ActualWidth;
     double h = chart.PlotArea.ActualHeight;
}

Method ValidateChartLayout() has been added to IChart interface and Chart class

Calculates actual values of chart elements. The actual values include position of elements that implement IActualLayout interface (IActualLayout.ActualX, IActualLayout.ActualY, IActualLayout.ActualWidth, IActualLayout.ActualHeight) and actual axes values (IAxis.ActualMaxValue, IAxis.ActualMinValue, IAxis.ActualMajorUnit, IAxis.ActualMinorUnit, IAxis.ActualMajorUnitScale, IAxis.ActualMinorUnitScale).

using (Presentation pres = new Presentation())
{
     Chart chart = (Chart)pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 100, 100, 500, 350);
     chart.ValidateChartLayout();
     double x = chart.PlotArea.ActualX;
     double y = chart.PlotArea.ActualY;
     double w = chart.PlotArea.ActualWidth;
     double h = chart.PlotArea.ActualHeight;
}

New method LoadExternalFont has been added to FontsLoader class

The new method LoadExternalFont has been added to FontsLoader class:

public static void LoadExternalFont(byte[] data)

This method allows to add font from the binary data.

// loading presentation uses SomeFont which is not installed on the system
using(Presentation pres = new Presentation("pres.pptx")
{
     // load SomeFont from file into the byte array
     byte[] fontData = File.ReadAllBytes(@"fonts\SomeFont.ttf"));

     // load font represented as byte array
     FontsLoader.LoadExternalFont(fontData);

     // font SomeFont will be available during the rendering or other operations
}

Ppt95 value has been added to Aspose.Slides.LoadFormat enumeration

The new Ppt95 value has been added to Aspose.Slides.LoadFormat enumeration. This value represents Microsoft PowerPoint 95 presentation format.

Code snippet to check whether the presentation format is old Microsoft PowerPoint 95:

bool isOldFormat = PresentationFactory.Instance.GetPresentationInfo(path).LoadFormat == LoadFormat.Ppt95;
