This project is a fork of Andrew Kirillow's original AForge.NET Framework project. For general information and tutorials, see here.
The repository currently provides:
- Portable Class Libraries for base and imaging functionality functionality (Core, Math, Genetic, Fuzzy, MachineLearning, Neuro, Imaging, Imaging.Formats, Vision),
- Portable Class Library Shim.Drawing to substitute .NET System.Drawing types not covered by PCL, and
- Target specific Shim.Drawing libraries for .NET Framework, Windows Store and Windows Phone 8.
The portable class libraries reference the portable Shim (on NuGet) and/or Shim.Drawing assemblies. In applications however, the target specific (Windows Store, Windows Phone or WPF) Shim and Shim.Drawing assemblies should be referenced, to ensure that the target specific version of each type is used.
WriteableBitmap:s provide input and output to the imaging functionality in the WPF, Windows Store and Windows Store libraries. The target specific Shim.Drawing assembly
incorporates explicit cast operators between WriteableBitmap and System.Drawing.Bitmap.
All image processing is performed on the mock System.Drawing.Bitmap class, WriteableBitmap objects should only be used as initial input to and final output from the
image processing.
When using the WPF Shim.Drawing assembly, the System.Drawing assembly from .NET Framework cannot be referenced since this would lead to type name collisions. If there is a need to reference the real System.Drawing assembly, you are recommended to use the original AForge.NET Framework libraries and use WPF hosting controls to display image processing results instead.
IMPORTANT!
- PCL projects cannot be built in Express versions of Visual Studio (prior to 2013 Update 2), but prebuilt PCL binaries can still be referenced. The latest prebuilt binaries for Portable AForge can be downloaded here.
- To be able to reference the target specific (Windows Store, WP8, .NET/WPF) Shim and Shim.Drawing assemblies, all underlying assemblies need to have a strong name, i.e. be signed.
This same approach can be applied in WPF, Windows Store and Windows Phone applications.
// Use explicit operator to convert from WriteableBitmap to Bitmap
Bitmap bitmap = (Bitmap)aWriteableBitmapObject;
// Apply one or more filter functions on the Bitmap object
var filter1 = AForge.Imaging.Filters.Grayscale.CommonAlgorithms.RMY;
bitmap = filter1.Apply(bitmap);
var filter2 = new AForge.Imaging.Filters.CannyEdgeDetector();
filter2.ApplyInPlace(bitmap);
// Use explicit operator to convert back from Bitmap to WriteableBitmap
aWriteableBitmapObject = (WriteableBitmap)bitmap;
Open the Portable Build All.sln solution file located in the Sources folder and build the entire solution or selected projects. Visual Studio 2012 Professional or higher is required.
