Please check the detailed [release notes of Aspose.Pdf for Java 17.2.0][3], in order to get an idea about the new features/enhancements and improvements made in this release of Aspose.Pdf for Java.

Furthermore, If you are planning to upgrade the API from any previous version, we strongly recommend you to check the [Public API Changes section of current release][4] and other intermediate releases from release notes pages, to know what has been changed since your current revision of the API.

The following sections describe some details regarding these newly added features/enhancements.

PDF to PDFA_3U Conversion

We have introduced [support of PDFA_3U][5] in this release. You can convert PDF to PDFA_3U standard using following code snippet.

Document doc = new Document("inFile.pdf"); 
PdfFormatConversionOptions opts = new PdfFormatConversionOptions("outLog.txt", PdfFormat.PDF_A_3U, ConvertErrorAction.Delete);

Chart extraction as image

Some of our customers asked for support of [Charts extraction from PDF document as image][6]. Chart object is placed as Marked Content object in PDF document. We have implemented a new method extractMarkedContentAsImage() in Aspose.Pdf for Java 17.2.0 to extract Marked Contents as image. Please check following code snippet to extract Chart objects.

//Open document
Document document = new Document("sample.pdf");
//instantiate PdfExtractor
PdfExtractor pdfExtractor = new PdfExtractor();
//Extract Chart objects as image in a folder
pdfExtractor.extractMarkedContentAsImages(document.getPages().get_Item(1), "C:/Temp/Charts_page_1");

PDF to Pixelated TIFF image

While converting PDF to compressed TIFF, customers requested [Pixelated TIFF output support][7]. We have implemented a new option Pixelated in com.aspose.pdf.devices.TiffSettings.IndexedConversionType class. Now it has two values: Pixelated and Simple. Simple is the default style of black and white conversion. Please find sample code as below:

//Open document
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("Input.pdf");
//Create stream object to save the output image
java.io.OutputStream imageStream = new java.io.FileOutputStream("Image.tiff");
//Create Resolution object
com.aspose.pdf.devices.Resolution resolution = new com.aspose.pdf.devices.Resolution(300);
//instantiate TiffSettings object
com.aspose.pdf.devices.TiffSettings tiffSettings  = new com.aspose.pdf.devices.TiffSettings();
//set the compression of resultant TIFF image
//set the color depth for resultant image
//skip blank pages while rendering PDF to TIFF
//set image brightness
//set IndexedConversion Type, default value is simple
//Create TiffDevice object with particular resolution
com.aspose.pdf.devices.TiffDevice   tiffDevice = new com.aspose.pdf.devices.TiffDevice(2480, 3508,resolution,tiffSettings);
//Convert a particular page (Page 1) and save the image to stream
//Close the stream


In addition to above stated enhancements and improvements, this version also includes some other important bug fixes as well. There have been specific improvements regarding PDF to PDFA conversion, HTML to PDF, PCL to PDF and PDF to PPTX conversion. Please check [release notes of Aspose.Pdf for Java 17.2.0][8] for complete list of bug fixed.
