This is an alternative TranscoderManager class to be used along with the well-known fo-dicom project. It is associated to C/C++ libraries compiled natively for several platforms. So far:
- Windows 64-bit (similar to Dicom.Native64.dll)
- Linux 64-bit (tested with Ubuntu 16/18 Desktop and Server)
- MacOS (tested with macOS High Sierra Version 10.13)
This transcoder differs from the existing fo-dicom implementations in the following:
- Unified C/C++ source code for all platforms.
- Does not implement a Managed C/C++ middleware. Direct C# to C/C++ integration.
- Avoids pure C# implementation for performance reasons (with exception of RLE).
The following CODECS are implemented:
- JPEG 2000 Image Compression (Lossless Only)
- JPEG 2000 Image Compression
- JPEG Baseline (Process 1): Default Transfer Syntax for Lossy JPEG 8 Bit Image Compression
- JPEG Extended (Process 2 & 4): Default Transfer Syntax for Lossy JPEG 12 Bit Image Compression - (Process 4 only)
- JPEG Lossless, Non-Hierarchical (Process 14)
- JPEG Lossless, Non-Hierarchical, First-Order Prediction (Process 14 [Selection Value 1]): Default Transfer Syntax for Lossless JPEG Image Compression
- JPEG-LS Lossless Image Compression
- JPEG-LS Lossy (Near-Lossless) Image Compression
- RLE Lossless
- Add the nuget package to your .Net Standard or .NetCore project
- Add the standard fo-dicom nuget packages to your project (tested with 4.0.2)
- At the beginning of your application, replace the transcoder manager, as:
Dicom.Imaging.Codec.TranscoderManager.SetImplementation(new Efferent.Native.Codec.NativeTranscoderManager());
- Continue using any fo-dicom image manipulation function.
