接下来,使用System.Drawing.Imaging.ImageFormat类的Jpeg格式属性,将Bitmap对象保存为JPEG格式的字节数组: 代码语言:csharp 复制 using(MemoryStreamms=newMemoryStream()){bitmap.Save(ms,System.Drawing.Imaging.ImageFormat.Jpeg);byte[]jpegBytes=ms.ToArray();} ...

这里传入的jbyteArray data_是nv21格式,首先转成nv21的Mat,然后在通过cv::cvtColor方法,通过cv::COLOR_YUV2RGBA_NV21这个参数值,转为rgba格式的Mat。 extern "C" JNIEXPORT jbyteArray JNICALL Java_com_heiko_myncnnlib_NcnnNativeLib_nv21toARGB(JNIEnv *env, jobject thiz, jbyteArray data_, ...

BitmapImage 主要是为了支持可扩展应用程序标记语言 (XAML) 语法,并引入了未定义的 BitmapSource位图加载的其他属性。BitmapImage 实现ISupportInitialize 接口,以对多个属性的初始化进行优化。 只能在对象初始化过程中进行属性更改。 调用 BeginInit 以指示初始化已开始,调用 EndInit 以指示初始化已结束...
