我正在尝试使用以下代码将MAt转换为位图:
Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Mat tmp = new Mat (width,height,CvType.CV_8UC1,new Scalar(4));
try {
//Imgproc.cvtColor(seedsImage, tmp, Imgproc.COLOR_RGB2BGRA);
Imgproc.cvtColor(seedsImage, tmp, Imgproc.COLOR_GRAY2RGBA, 4);
Utils.matToBitmap(tmp, bmp);}
catch (CvException e){Log.d("Exception",e.getMessage());}
我的seedsImage是一个Mat对象.而Exception和got是10-09 22:15:09.418: D/Exception(2461): ..\..\modules\java\generator\src\cpp\utils.cpp:105: error: (-215) src.dims == 2 && info.height == (uint32_t)src.rows && info.width == (uint32_t)src.cols in function void Java_org_opencv_android_Utils_nMatToBitmap2(JNIEnv*, _jclass*, jlong, _jobject*, jboolean)
我试图搜索但没有解决方案适合我.任何人都可以帮忙吗？
我正在尝试使用WT-NMP安装cakePHP 3.0.0,但我收到此消息:

我没有通过gdxsetup.jar创建项目,我只包括gdx.jar和gdx-backend-android.jar.我将libgdx.so添加到libs/x86,但它仍然会引发异常.我该怎么解决这个问题？
