It is also recommended to go through the release notes pages of these releases before downloading and using it in your environment. Release notes are present in respective API documentation over below links:

Following section includes insights into worth mentioning features in this release of Aspose.PDF API.

Optimize PDF Resources

It was observed that execution time of OptimizeResources method was slow in earlier version(s) of the API which was due to slow image compression. In this release of the API, new image compression algorithms have been implemented which work faster and you can optimize PDF documents in an improved and faster way. Following sample code snippet can be used to optimize PDF resources using new implemented properties:

[C#.NET]

Document doc = new Document("source.pdf");        

Aspose.Pdf.Optimization.OptimizationOptions opt =

new Aspose.Pdf.Optimization.OptimizationOptions(); opt.LinkDuplcateStreams = true; opt.RemoveUnusedObjects = false; opt.AllowReusePageContent = true; opt.RemoveUnusedStreams = true; opt.UnembedFonts = false; opt.ImageCompressionOptions.CompressImages = true; opt.ImageCompressionOptions.ImageQuality = 50; opt.ImageCompressionOptions.ResizeImages = false; opt.ImageCompressionOptions.Version = ImageCompressionVersion.Fast; doc.OptimizeResources(opt);

[Java]

Document doc = new Document("source.pdf"); 
com.aspose.pdf.optimization.OptimizationOptions opt =
new com.aspose.pdf.optimization.OptimizationOptions();
opt.setLinkDuplcateStreams(true);
opt.setRemoveUnusedObjects(false);
opt.setAllowReusePageContent(true);
opt.setRemoveUnusedStreams(true);
opt.setUnembedFonts(false);
opt.getImageCompressionOptions().setCompressImages(true);
opt.getImageCompressionOptions().setImageQuality(50);
opt.getImageCompressionOptions().setResizeImages(false);
opt.getImageCompressionOptions().setVersion(ImageCompressionVersion.Fast);
doc.optimizeResources(opt);

Miscellaneous Fixes

Along with the features mentioned above, following are some useful improvement which have been included in this release of the API:

  • Implemented precise coordinate calculations for characters
  • Improvements have been made for working with Form Fields
  • Hyperlink Alignment issues have been rectified
  • Improved PDF Printing time taken by the API
  • Color corrections have been made during PDF to TIFF conversion
  • Table Extraction and Manipulation algorithms have further been enhanced
  • Functionality to support text and fonts has been added for PDF/UA format
