Public API Changes

createTextFrameFormatEffective() method has been added to TextFrame class and ITextFrame interface

It returns effective value of text frame format for the TextFrame object. Returned type is ITextFrameFormatEffectiveData.

Interface com.aspose.slides.ITextFrameFormatEffectiveData has been added

Represents effective values (formatting values with inheritance applied) of text frame format. It contains the following methods:

  • ITextStyleEffectiveData getTextStyle() — Returns effective text’s style.
  • double getMarginLeft() — Returns the left margin (points) in a TextFrame.
  • double getMarginRight() — Returns the right margin (points) in a TextFrame.
  • double getMarginTop() — Returns the top margin (points) in a TextFrame.
  • double getMarginBottom() — Returns the bottom margin (points) in a TextFrame.
  • boolean getWrapText() — Returns if text is wrapped at TextFrame’s margins.
  • byte getAnchoringType() — Returns vertical anchor text in a TextFrame.
  • boolean getCenterText() — Returns if text should be centered in box horizontally.
  • byte getTextVerticalType() — Returns text orientation.
  • byte getAutofitType() — Returns text autofit mode.

Code example:

Presentation pres = new Presentation("pres.pptx");
try{
    ISlide slide = pres.getSlides().get_Item(0);
    IShape shape = slide.getShapes().get_Item(0);
    ITextFrame textFrame = ((AutoShape)shape).getTextFrame();
    ITextFrameFormatEffectiveData textFrameFormatEffective = textFrame.createTextFrameFormatEffective();
    System.out.println("margin top: " + textFrameFormatEffective.getMarginTop());
    System.out.println("margin left: " + textFrameFormatEffective.getMarginLeft());
    System.out.println("margin right: " + textFrameFormatEffective.getMarginRight());
    System.out.println("margin bottom: " + textFrameFormatEffective.getMarginBottom());
} finally {
    if(pres != null) pres.dispose();
}

Interface com.aspose.slides.ITextStyleEffectiveData has been added

Represents effective values (formatting values with inheritance applied) of text style. It contains the following methods:

  • IParagraphFormatEffectiveData getLevel(int index) — Returns level of effective style.
  • IParagraphFormatEffectiveData getDefaultParagraphFormat() — Returns effective default paragraph properties.

Code example:

Presentation pres = new Presentation("pres.pptx");
try{
    ISlide slide = pres.getSlides().get_Item(0);
    IShape shape = slide.getShapes().get_Item(0);
    ITextFrame textFrame = ((AutoShape)shape).getTextFrame();
    ITextFrameFormatEffectiveData textFrameFormatEffective = textFrame.createTextFrameFormatEffective();

    ITextStyleEffectiveData textStyleEffective = textFrameFormatEffective.getTextStyle();

} finally {
    if(pres != null) pres.dispose();
}

New classes were added, intended to provide the functionality to embed EOT and WOFF fonts into generated HTML document

The two new classes were added to provide the functionality to embed WOFF and EOT fonts into generated HTML document:

  • EmbeddedWoffFontsHtmlController
  • EmbeddedEotFontsHtmlController

Below is an example of how to use the new EmbeddedWoffFontsHtmlController class to export HTML with embedded WOFF fonts:

Presentation pres = new Presentation("pres.pptx");
try
{
    EmbeddedWoffFontsHtmlController controller = new EmbeddedWoffFontsHtmlController();
    HtmlOptions htmlOptions = new HtmlOptions();
    htmlOptions.setHtmlFormatter(HtmlFormatter.createCustomFormatter(controller));

    pres.save("pres.html", SaveFormat.Html, htmlOptions);
} finally {
    if(pres != null) pres.dispose();
}

New interface IResponsiveHtmlController and class ResponsiveHtmlController have been added

The new class was added intended to provide the responsive HTML to the generated HTML files: ResponsiveHtmlController.

This controller can be used in the same manner as other HTML controllers:

Presentation pres = new Presentation("pres.pptx");
try
{
    ResponsiveHtmlController controller = new ResponsiveHtmlController();
    HtmlOptions htmlOptions = new HtmlOptions();
    htmlOptions.setHtmlFormatter(HtmlFormatter.createCustomFormatter(controller));

    pres.save("pres.html", SaveFormat.Html, htmlOptions);
} finally {
    if(pres != null) pres.dispose();
}

New methods have been added to com.aspose.slides.FontsManager

The following new methods have been added to IFontsManager interface and FontsManager class:

IFontData[] getEmbeddedFonts() - this method returns the fonts embedded in the presentation.
void removeEmbeddedFont(IFontData fontData) - this method removes the embedded font from the presentation.

There is the sample demonstrates the use case for these new methods:

// load the presentation with embedded "FunSized" font in it
Presentation pres = new Presentation("pres.ppt");
try
{
    // render the presentation containing the text frame with the text using embedded "FunSized" font
    ImageIO.write(pres.getSlides().get_Item(0).getThumbnail(new Dimension(960, 720)), "PNG", new File("pres-1.png"));

    IFontsManager fontsManager = pres.getFontsManager();

    // get all embedded fonts
    IFontData[] embeddedFonts = fontsManager.getEmbeddedFonts();

    // find "FunSized" font
    IFontData funSizedEmbeddedFont = null;
    for(int i = 0; i < embeddedFonts.length; i++)
        if("FunSized".equals(embeddedFonts[i].getFontName())){
            funSizedEmbeddedFont = embeddedFonts[i];
            break;
        }

    // remove "FunSized" font
    fontsManager.removeEmbeddedFont(funSizedEmbeddedFont);

    // render the presentation after removing the "FunSized" font resulting in a font replacement from "FunSized" to an existing one
    ImageIO.write(pres.getSlides().get_Item(0).getThumbnail(new Dimension(960, 720)), "PNG", new File("pres-2.png"));

    // save the presentation without embedded "FunSized" font
    pres.save("37537-2.ppt", SaveFormat.Ppt);
} finally {
    if(pres != null) pres.dispose();
}
