What is new in this release?

Aspose development team is pleased to announce the new release Aspose.Imaging for Java 2.7.0. . This release contains many useful improvements; Most worth mentioning enhancement is the support for DWG 2005 revision 16.1, 2010 revision 18.0 and 2013 revision 19.0 AutoCAD formats. Starting with this release, Aspose.Imaging for Java has dropped the support for Java versions prior to v6 and has moved its codebase to Java 6 (Java 7 and 8 are also supported). Reason being, Sun/Oracle has discontinued the support for all JDK revisions prior to 1.6. Now the Aspose.Imaging for Java package contains a single Jar that works well with Java 6, 7 & 8. Aspose.Imaging for Java API can load AutoCAD drawings for possible conversion to PDF and raster image formats. With this release, the API has extended its support for the said conversion by allowing the users to select multiple layouts from a given DWG or DXF drawing, and render them to PDF or raster image formats. The API has exposed the CadRasterizationOptions.Layouts property of type String[] so you may specify more than one layouts at a time. While specifying multiple layouts for the CadRasterizationOptions.Layouts property, the resultant PDF and TIFF image would have multiple pages, GIF image would have multiple frames and PSD format would have multiple layers, where each page/frame/layer represents an individual AutoCAD layout. In case any other image format such as PNG, BMP, JPEG is selected to store the result then the API will render only the default layout; that is “Model”. Aspose.Imaging for Java API conceals the ugly details and provides an easy to use mechanism to specify ICC profiles via JpegImage class. Moreover, Aspose.Imaging uses the sample profiles of SWOP CMYK and sRGB embedded into its core therefore in most common usage cases, you do not need to seek for any specific profiles. Previously, Aspose.Imaging allowed to set the transparency color for PNG format. With this release, the API has extended its support for the GIF image, and have improved the public API to make the usability even simpler by exposing the relevant properties to the RasterImage class. The main new and improved features added in this release are listed below

Overview: Aspose.Imaging for Java

Aspose.Imaging for .NET is an image processing & manipulation component that allows developers to create, edit, draw or convert images in their .NET application. It allows developers to convert image files to PSD, BMP, JPEG, PNG, TIFF and GIF formats. Moreover a set of pens, brushes and fonts can be used to draw images or add new elements & text to existing images. Aspose.Imaging for .NET works well with both web & windows applications. Moreover, it adds the support for Silverlight platform.
