What's new in Aspose.Imaging for .NET 2.4.0
May 9, 2014
- Major Features:
- Dwg to Pdf conversion is now available. Now we support reading and conversion to Pdf of the Autocad 2004 Dwg file format (version 16.0 Release 18). We continue the hard work to support the other Autocad versions and Autocad 2010 support is currently under development. Please note we currently support the following main Autocad 2004 primitives: TEXT, MTEXT, ATTDEF, ATTRIB, ARC, ELLIPSE, HATCH, LEADER, POINT, VERTEX 2D, VERTEX 3D, POLYLINE 2D, LWPOLYLINE, RAY, CIRCLE, DIMENSION ORDINATE, DIMENSION LINEAR, DIMENSION ALIGNED, DIMENSION ANG 3Pt, DIMENSION ANG 2Ln, DIMENSION RADIUS, DIMENSION DIAMETER, SHAPE, SOLID, SPLINE, MLINE, LINE, XLINE, STYLE, DIMSTYLE, LTYPE, MLINESTYLE, LAYER, VIEWPORT, LAYOUT.
- Additionally we have greatly reworked the Imaging engine and improved the overall performance for bmp file format (IMAGING-34110). The bmp file format now supports raw data loading and processing of the bmp file format is now greatly improved. We will continue the raw data support and future releases will contain more file formats covering that feature.

New in Aspose.Imaging for .NET 2.2.0 (Apr 1, 2014)
- Major Features
- Data recovery for Tiff:
- Starting from v2.2 Aspose.Imaging supports data recovery mode for tiff file format (IMAGING-33851). The data recovery allows to load any tiff file which has improper data layout or some data corruption exist. The corrupted data is replaced with some background defined and you will be able to retrieve the rest data and view its contents. This is especially useful for tiff file format since it stores the data in strips and when some strip is damaged the other strips may still retain the correct information and data recovery mode allows loading and viewing the rest strips data. To assist our customers we have also provided support for 2 data recovery modes: ConsistentRecover and MaximalRecover which may provide different results depending on the customer needs for data recovery.
