Aspose.Imaging for Java has been updated to version 3.2 and we are pleased to announce it.
The following is a list of changes in this version of Aspose.Imaging:
New features
IMAGING-35046 - Converting WMF to PNG format producing low quality png images and some time totally blank images Java
IMAGING-35032 - Support FontSettings for CAD formats.IMAGING-34971 Support for embedded external images for dwg/dxf
IMAGING-34908 Implementation of Bradley thresholding
IMAGING-34851 Allow crop or expand for images when they exported to raster file formats
IMAGING-34291 Export PSD layer(s) to a raster image(s) via file path location and stream
IMAGING-34896 Support export of CAD drawing as image embedded into PDF file
Enhancements
IMAGING-35048 Expose useful tiff classes and stream classes to public
IMAGING-35013 Only contiguous planar configuration is supported at the moment exception when trying to loading a tiff image
IMAGING-35008 Could not update EXIF data with null properties
IMAGING-34946 Psd image saving throws System.IndexOutOfRangeException: Index was outside the bounds of the array.
IMAGING-34945 Exporting DWG Drawing to PDF produces invalid results
IMAGING-34944 Incorrect dimensions returned for certain DXF
IMAGING-34927 Converting DxF file to png or tiff, resulting in an empty output file.

IMAGING-34878 Error in documentation/implementation for Aspose.Imaging for Save() method for PSD with concrete PsdOptions specified
IMAGING-34877 Empty PSD file after Save() source PSD without max compatibility with CompressionMethod.Raw
IMAGING-34876 PSD layers in result file lost after Save() call with CompressionMethod.Raw
IMAGING-34664 Drawing a PNG with transparent background on another image results in a black block
IMAGING-34590 Colors change when TIFF is converted to JPEG with default settings
IMAGING-34345 Improve tiff loading performance
