What is new in this release?

Aspose development team is pleased to announce the new release Aspose.Imaging for Java 3.0.0. . This month’s release contains many useful improvements including the long awaited support for DjVu file format. Please refer to the release notes of Aspose.Imaging for Java 3.0.0 for a full list of bug fixes and improvements along with sample code snippets for newly added features. DjVu file format is becoming popular as an alternative to PDF because it has smaller file size as compared to PDF. DjVu format can also be considered as a superior alternative to PDF for digital documents, to TIFF for scanned bitonal documents, to JPEG and JPEG2000 for photographs and pictures, and to GIF for large palatalized images. With the release of Aspose.Imaging for Java 3.0.0, the API has provided the support for loading DjVu files for possible conversion to raster image formats as well as PDF. In order to provide this support, the API has exposed DjvuImage class along with many new helping classes, methods & properties listed in the Public API Changes in Aspose.Imaging for Java 3.0.0. Like PDF & TIFF, the DjVu files can have multiple pages/frames therefore while converting the DjVu files to raster formats such as TIFF & GIF, all pages of DjVu are rendered to the resultant image by default. Aspose.Imaging for Java 3.0.0 can also be used to convert the DjVu files to PDF format while using the existing PdfOptions class. It is up to the user requirement if all DjVu pages or a subset of the pages are to be exported in PDF format. Aspose.Imaging for Java 3.0.0 has exposed a new class IntRange that can be used to specify a range that in turn can be passed to an instance of DjvuMultiPageOptions for the conversion of specific range of DjVu pages to TIFF or GIF. It is also possible to store each DjVu page to separate raster image. In order to achieve this goal, the latest version of Aspose.Imaging for Java 3.0.0 has exposed an overload constructor of DjvuMultiPageOptions that could accept an integer value to export the specific page. This mechanism can be extended to render individual DjVu pages to raster formats. Another overload constructor of DjvuMultiPageOptions class can accept an integer value as well as an instance of Rectangle to export a specific portion of DjVu page to raster image format. As always we appreciate your feedback so if you ever have anything to tell us about this release or anything else, please head to the Aspose.Imaging forum for a chat. The main new and improved features added in this release are listed below
