Imebra

Imebra是用C++编写的DICOM库，支持多平台编译Linux, Windows, OS-X, iOS, Android。支持DICOM数据解析、支持压缩图片格式、支持DICOMDIR、支持Dicom3 & NEMA标准

examples 可以生成三个小程序
library c++源码
wrappers 包含python java的部分代码

创建项目

1.创建一个Android Studio项目在imebra目录下
2.为该项目添加一个Android Library

3.往Library添加创建src/main创建cpp文件夹

4.将wrapper/javaWrapper/src/所有文件复制到Library的src/main/java下
5.将wrapper/java_wrapper.cxx复制到Library的/src/main/java
6.Library目录下创建CMakeLists.txt 文件

cmake_minimum_required(VERSION 3.4.1)include_directories(../../library/include)aux_source_directory(../../library/implementation/ IMPL_SRCS)aux_source_directory(../../library/src/ DIR_SRCS)aux_source_directory(src/main/cpp/ JNI_SRC)link_directories(libs)add_library( # Sets the name of the library.             imebra             # Sets the library as a shared library.             SHARED             # Provides a relative path to your source file(s).             ${JNI_SRC}             ${IMPL_SRCS}             ${DIR_SRCS}             )find_library( # Sets the name of the path variable.              log-lib              # Specifies the name of the NDK library that              # you want CMake to locate.              log )target_link_libraries( # Specifies the target library.                       imebra                       # Links the target library to the log library                       # included in the NDK.                       ${log-lib}                     )

include_directories 加载头文件
aux_source_directory加载目录下的所有文件
find_library 加载指定库
target_link_libraries 生成动态库

7.修改Library的build.gradle

android {       defaultConfig {               externalNativeBuild {            cmake {                cppFlags "-std=c++11 -DIMEBRA_USE_JAVA -DIMEBRA_MEMORY_POOL_MAX_SIZE=4000000 -fexceptions -pthread"            }            ndk {                abiFilters'armeabi', 'armeabi-v7a'            }        }    }        externalNativeBuild {        cmake {            path "CMakeLists.txt"        }    }}

cppFlags 使用c11标准编译IMEBRA转码部分使用JAVA转码设置内存池大小

8.com.imebra.imebraJNI类添加

static {    System.loadLibrary("imebra");  }

9.加载图片

public void loadDICOM(String name){        String newPath = getCacheDir()+"/"+name;        copyFilesFassets(this,name,newPath);        DataSet dataSet = CodecFactory.load(newPath);        Image image = dataSet.getImage(0);        Log.d("height",""+image.getHeight());        Log.d("width",""+image.getWidth());        long height = image.getHeight();        long width = image.getWidth();        com.imebra.TransformsChain chain = new com.imebra.TransformsChain();        if(com.imebra.ColorTransformsFactory.isMonochrome(image.getColorSpace()))        {            // Allocate a VOILUT transform. If the DataSet does not contain any pre-defined            //  settings then we will find the optimal ones.            VOILUT voilutTransform = new VOILUT();            // Retrieve the VOIs (center/width pairs)            VOIs vois = dataSet.getVOIs();            // Retrieve the LUTs            List luts = new ArrayList();            for(long scanLUTs = 0; ; scanLUTs++)            {                try                {                    luts.add(dataSet.getLUT(new com.imebra.TagId(0x0028,0x3010), scanLUTs));                }                catch(Exception e)                {                    break;                }            }            if(!vois.isEmpty())            {                voilutTransform.setCenterWidth(vois.get(0).getCenter(), vois.get(0).getWidth());            }            else if(!luts.isEmpty())            {                voilutTransform.setLUT(luts.get(0));            }            else            {                voilutTransform.applyOptimalVOI(image, 0, 0, width, height);            }            chain.addTransform(voilutTransform);        }        com.imebra.DrawBitmap draw = new com.imebra.DrawBitmap(chain);// Ask for the size of the buffer (in bytes)        long requestedBufferSize =width*height*4;        byte buffer[] = new byte[(int)requestedBufferSize]; // Ideally you want to reuse this in subsequent calls to getBitmap()        ByteBuffer byteBuffer = ByteBuffer.wrap(buffer);// Now fill the buffer with the image data and create a bitmap from it        draw.getBitmap(image, drawBitmapRGBA, 4, buffer);        Bitmap renderBitmap = Bitmap.createBitmap((int)image.getWidth(), (int)image.getHeight(), Bitmap.Config.ARGB_8888);        renderBitmap.copyPixelsFromBuffer(byteBuffer);        ImageView imageView = (ImageView) findViewById(R.id.image);        imageView.setImageBitmap(renderBitmap);    }
