Public API Changes

Default public constructors have been added to PortionFormat, ParagraphFormat and TextFrameFormat classes

Default public constructors have been added to PortionFormat, ParagraphFormat and TextFrameFormat classes. Formats created with these constructions using can be used to specify text formats for a whole table, etc.

Usage Example:

PortionFormat portionFormat = new PortionFormat();
ParagraphFormat paragraphFormat = new ParagraphFormat();
TextFrameFormat textFrameFormat = new TextFrameFormat();

IBulkTextFormattable interface has been added

Aspose.Slides.IBulkTextFormattable interface has been added. It represents an object with possibility of bulk setting child text elements' formats. It contains the following methods:

void SetTextFormat(IPortionFormat source);
void SetTextFormat(IParagraphFormat source);
void SetTextFormat(ITextFrameFormat source);

Calling any of them will make an object of class that implements this interface set all its child portions / paragraphs / text frames (accordingly to used method overload) with all defined properties from provided format sample.
IFormatFactory interface and FormatFactory class have been added

Aspose.Slides.IFormatFactory interface and Aspose.Slides.FormatFactory class have been added. They allow to create PortionFormat, ParagraphFormat and TextFrameFormat instances via COM interface.

Usage Example:

IPortionFormat portionFormat = FormatFactory.Instance.CreatePortionFormat();
IParagraphFormat paragraphFormat = FormatFactory.Instance.CreateParagraphFormat();
ITextFrameFormatparagraphFormat = FormatFactory.Instance.CreateTextFrameFormat();
Properties DataLabelFormat.ShowLabelValueFromCell and IDataLabelFormat.ShowLabelValueFromCell have been added

Property DataLabelFormat.ShowLabelValueFromCell determines if data label text contains data from workbook data cell.

string lbl0 = "Label 0 cell value";
string lbl1 = "Label 1 cell value";
string lbl2 = "Label 2 cell value";

using (Presentation pres = new Presentation())
{
IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Bubble, 50, 50, 600, 400, true);

IChartSeriesCollection series = chart.ChartData.Series;

series[0].Labels.DefaultDataLabelFormat.ShowLabelValueFromCell = true;

IChartDataWorkbook wb = chart.ChartData.ChartDataWorkbook;

series[0].Labels[0].ValueFromCell = wb.GetCell(0, "A10", lbl0);
series[0].Labels[1].ValueFromCell = wb.GetCell(0, "A11", lbl1);
series[0].Labels[2].ValueFromCell = wb.GetCell(0, "A12", lbl2);
}

Properties IDataLabel.ValueFromCell and DataLabel.ValueFromCell have been added

Gets or sets workbook data cell. Applied if IDataLabelFormat.ShowLabelValueFromCell property equals true.

string lbl0 = "Label 0 cell value";
string lbl1 = "Label 1 cell value";
string lbl2 = "Label 2 cell value";

using (Presentation pres = new Presentation())
{
IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Bubble, 50, 50, 600, 400, true);

IChartSeriesCollection series = chart.ChartData.Series;

series[0].Labels.DefaultDataLabelFormat.ShowLabelValueFromCell = true;

IChartDataWorkbook wb = chart.ChartData.ChartDataWorkbook;

series[0].Labels[0].ValueFromCell = wb.GetCell(0, "A10", lbl0);
series[0].Labels[1].ValueFromCell = wb.GetCell(0, "A11", lbl1);
series[0].Labels[2].ValueFromCell = wb.GetCell(0, "A12", lbl2);

pres.Save(outPath, SaveFormat.Pptx);
}

SetTextFormat methods have been added to Column class due to inheritance from IBulkTextFormattable added to IColumn interface

Aspose.Slides.Column class now implements IBulkTextFormattable interface as a part of IColumn interface. Portion, paragraph or text frame format properties can be set to all column cells by calling Column.SetTextFormat methods.

Usage Examples:

ITable someTable = presentation.Slides[0].Shapes[0] as ITable; // let's say that the first shape on the first slide is a table

// setting first column cells' font height
PortionFormat portionFormat = new PortionFormat();
portionFormat.FontHeight = 25;
someTable.Columns[0].SetTextFormat(portionFormat);

// setting first column cells' text alignment and right margin in one call
ParagraphFormat paragraphFormat = new ParagraphFormat();
paragraphFormat.Alignment = TextAlignment.Right;
paragraphFormat.MarginRight = 20;
someTable.Columns[0].SetTextFormat(paragraphFormat);

// setting second column cells' text vertical type
TextFrameFormat textFrameFormat = new TextFrameFormat();
textFrameFormat.TextVerticalType = TextVerticalType.Vertical;
someTable.Columns[1].SetTextFormat(textFrameFormat);

SetTextFormat methods have been added to Row class due to inheritance from IBulkTextFormattable added to IRow interface

Aspose.Slides.Row class now implements IBulkTextFormattable interface as a part of IRow interface. Portion, paragraph or text frame format properties can be set to all row cells by calling Row.SetTextFormat methods.

Usage Examples:

ITable someTable = presentation.Slides[0].Shapes[0] as ITable; // let's say that the first shape on the first slide is a table

// setting first row cells' font height
PortionFormat portionFormat = new PortionFormat();
portionFormat.FontHeight = 25;
someTable.Rows[0].SetTextFormat(portionFormat);

// setting first row cells' text alignment and right margin in one call
ParagraphFormat paragraphFormat = new ParagraphFormat();
paragraphFormat.Alignment = TextAlignment.Right;
paragraphFormat.MarginRight = 20;
someTable.Rows[0].SetTextFormat(paragraphFormat);

// setting second row cells' text vertical type
TextFrameFormat textFrameFormat = new TextFrameFormat();
textFrameFormat.TextVerticalType = TextVerticalType.Vertical;
someTable.Rows[1].SetTextFormat(textFrameFormat);

SetTextFormat methods have been added to Table class due to inheritance from IBulkTextFormattable added to ITable interface

Aspose.Slides.Table class now implements IBulkTextFormattable interface as a part of ITable interface. Portion, paragraph or text frame format properties can be set to all table cells by calling Table.SetTextFormat methods.

Usage Examples:

ITable someTable = presentation.Slides[0].Shapes[0] as ITable; // let's say that the first shape on the first slide is a table

// setting table cells' font height
PortionFormat portionFormat = new PortionFormat();
portionFormat.FontHeight = 25;
someTable.SetTextFormat(portionFormat);

// setting table cells' text alignment and right margin in one call
ParagraphFormat paragraphFormat = new ParagraphFormat();
paragraphFormat.Alignment = TextAlignment.Right;
paragraphFormat.MarginRight = 20;
someTable.SetTextFormat(paragraphFormat);

// setting table cells' text vertical type
TextFrameFormat textFrameFormat = new TextFrameFormat();
textFrameFormat.TextVerticalType = TextVerticalType.Vertical;
someTable.SetTextFormat(textFrameFormat);

SlideSizeScaleType enum, ISlideSize.SetSize and SlideSize.SetSize methods have been added

New methods SetSize have been added to SlideSize class and ISlideSize interface.

void SetSize(SlideSizeType type, SlideSizeScaleType scaleType);
void SetSize(float width, float height, SlideSizeScaleType scaleType);

These methods allow changing slide size with different ways of content scaling. Ways of content scaling are defined in new SlideSizeScaleType enum. There are following values.

DoNotScale - do not scale slide content. Use this for set the size without modification content.
EnsureFit - Scale to ensure fit. Use this for scale it down to ensure it will fit on slide.
Maximize - Maximize size of content. Use this for maximize the size of your content.

Usage example:

using (Presentation presentation = new Presentation("presentation.ppt"))
{
presentation.SlideSize.SetSize(540, 720, SlideSizeScaleType.EnsureFit); // Method SetSize is used for set slide size with scale content to ensure fit
presentation.SlideSize.SetSize(SlideSizeType.A4Paper, SlideSizeScaleType.Maximize); // Method SetSize is used for set slide size with maximize size of content
}

The property Size of interface ISlideSize and class SlideSize has been marked as Obsolete.

The property Type of interface ISlideSize and class SlideSize has been marked as Obsolete.
