Class OpenCVTypeAdapters

java.lang.Object

qupath.opencv.io.OpenCVTypeAdapters

public class OpenCVTypeAdapters
extends Object

Helper classes for combining OpenCV's JSON serialization with Gson's.

Sample use:

 Gson gson = new GsonBuilder()
                                .registerTypeAdapterFactory(OpenCVTypeAdapters.getOpenCVTypeAdaptorFactory())
                                .setPrettyPrinting()
                                .create();
 
 Mat mat1 = Mat.eye(3, 3, CV_32F1).asMat();
 String json = gson.toJson(mat1);
 Mat mat2 = gson.fromJson(json, Mat.class);

Method Details

getOpenCVTypeAdaptorFactory

public static TypeAdapterFactory getOpenCVTypeAdaptorFactory()

Get a TypeAdapterFactory to pass to a GsonBuilder to aid with serializing OpenCV objects (e.g. Mat, StatModel).

Returns:

getTypeAdaptor

public static <T> TypeAdapter<T> getTypeAdaptor(Class<T> cls)

Get a TypeAdapter to pass to a GsonBuilder for a specific supported OpenCV class, i.e. Mat, SparseMat or StatModel.

Parameters:

cls -

Returns:

the required TypeAdaptor, or null if no supported adapter is available for the class.
