Aspose.Slides for Java 24.4 Release Notes

Public API Changes

Introducing a new Modern API

Historically, Aspose Slides has a dependency on java.awt and has in the public API the following classes from there:

• Graphics2D
• BufferedImage

This means that all public API members that have the following classes in their signature will be removed in version 24.8:

For more details, see: Modern API

Added the following classes and enums to the public API:

• IImage - Represents the raster or vector image.
• ImageFormat - Represents the file format of the image.
• Images - The static class that contains methods to instantiate IImage.

Methods to be removed and their replacement in Modern API

The following methods and properties are decared as obsolete and will be removed in version 24.8.

PdfOptions.RasterizeUnsupportedFontStyles property added

Added a new property PdfOptions.RasterizeUnsupportedFontStyles which indicates whether text should be rasterized as a bitmap and saved to PDF when the font does not support bold styling. This approach can enhance the quality of text in the resulting PDF for certain fonts.

Example:

Presentation pres = new Presentation();
try {
    PdfOptions pdfOptions = new PdfOptions();
    pdfOptions.setRasterizeUnsupportedFontStyles(true);
    pres.save("pres.pdf", SaveFormat.Pdf, pdfOptions);
} finally {
    if (pres != null) pres.dispose();
}

PptxOptions.Zip64Mode property added - ZIP64 format support

A new property PptxOptions.Zip64Mode specifies whether the ZIP64 format is used for the Presentation document.

Example:

Presentation pres = new Presentation("demo.pptx");
try {
    PptxOptions pptxOptions = new PptxOptions();
    pptxOptions.setZip64Mode(Zip64Mode.Always);
    pres.save("demo-zip64.pptx", SaveFormat.Pptx, pptxOptions);
} finally {
    if (pres != null) pres.dispose();
}

ZoomObject.Image property replaced with ZoomObject.ZoomImage

Instead of ZoomObject.Image, use the ZoomObject.ZoomImage property:

Presentation pres = new Presentation("pres.pptx");
try {
    IZoomFrame zoomFrame = pres.getSlides().get_Item(0).getShapes().addZoomFrame(150, 20, 50, 50, pres.getSlides().get_Item(1));
    IPPImage image = pres.getImages().addImage(Images.fromFile("image.png"));
    zoomFrame.setZoomImage(image);
} finally {
    if (pres != null) pres.dispose();
}
