An Upgraded and Modern API

Aspose.Slides for Node.js via Java version 24.4 delivers a fresh approach to image management within your PowerPoint presentations with the addition of new classes like IImage and ImageFormat.

Improved Rendering

Develop Node.js applications to generate high-quality presentation thumbnails and render presentations to various formats with ease.

Font Rasterization to PDF Enhancements

You can maintain text quality in PDFs with the PdfOptions.RasterizeUnsupportedFontStyles property added to this release of the Node.js presentation processing API. Please check out this sample code to learn how this property works to rasterize bold font style in bitmap and export to PDF.

var pres = new aspose.slides.Presentation();
var pdfOptions = new aspose.slides.PdfOptions();
pdfOptions.setRasterizeUnsupportedFontStyles(true);
pres.save("pres.pdf", aspose.slides.SaveFormat.Pdf, pdfOptions);
pres.dispose();

ZIP64 Support for Larger Presentations

In this release of the PowerPoint API, we have introduced a new property, PptxOptions.Zip64Mode, for presentations exceeding standard ZIP size limitations. This code example demonstrates how you can use the new property, to export presentations with ZIP64 compression.

var pres = new aspose.slides.Presentation("demo.pptx");
var pptxOptions = new aspose.slides.PptxOptions();
pptxOptions.setZip64Mode(aspose.slides.Zip64Mode.Always);
pres.save("demo-zip64.pptx", aspose.slides.SaveFormat.Pptx, pptxOptions);
pres.dispose();
