dcm4che3与jai_imageio-1.1对我来说没有用。它不会让你转换jpegloss dicom图像。通常,它会转换大部分图像,但在读取dicom文件中的jpeg时会出现CLibJPEGImageReader错误。有人想出来了吗?
codecLib error
实际上我使用dcm4che2和旧的jai_imageio-1.0_01来解决这个问题。 您仍然可以将新的dcm4che3用于其他目的,但要注意您用于dcm4che3的子库。 dcm2dcm或Dcm2的dcm2之后,它将下载其jai_imageio-3.3依赖项,这将破坏您的转换
如果您遇到同样的问题,请执行以下步骤。
第一步:
首先确保在Spring Framework Java Application上使用32位JVM。
C:\ Program Files(x86)\ Java \ jdk1.7.0 \ jre \ bin
第二步:
让我再说一遍,这很重要:新的dcmche3 api和jai_1.1不适用于所有dcm文件转换为jpeg文件。一些带有JpegLoss合并图像的dcm文件无法转换为jpegs,这会导致codelLib错误或com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageReader错误
解决方案:
请jai_image-1.0_01版本以及dcm4che-core-2.0.25, dcm4che-image-2.0.25和dcm4che-imageio-2.0.25
你需要旧的jai libs
<dependency>
<groupId>com.sun.media</groupId>
<artifactId>jai_imageio</artifactId>
<version>1.0_01</version>
</dependency>
<dependency>
<groupId>javax.media</groupId>
<artifactId>jai_core</artifactId>
<version>1.1.2_01</version>
</dependency>
我们需要dcm4che-core的版本2.0.25和dcm4che-imageio来转换jpeg图像。带有jpegloss图像的dcm文件无法使用dcm 3.3.0进行转换,因此我们使用旧版本2.0.25
<dependency>
<groupId>dcm4che</groupId>
<artifactId>dcm4che-core</artifactId>
<version>2.0.25</version>
</dependency>
<dependency>
<groupId>dcm4che</groupId>
<artifactId>dcm4che-imageio</artifactId>
<version>2.0.25</version>
</dependency>
第3步: 现在是时候使用自定义Dcm2Jpeg类,你可以复制粘贴这个很久以前属于Gunter Zeilinger的代码来进行你的jpeg转换。它使用上面提到的2.0.25 dcm4che库。它虽然陈旧但却像魅力一样

第4步: 您仍然可以使用dcm4che-core-3.3.0,dcm4che-net-3.3.0,dcm4che-tool-storescp-3.3.0等。 但不要使用 dcm4che-dcm2jpg-3.3.0 或 dcm4che-dcm2dcm-3.3.0 。它们都会包含依赖关系cm4che- imageio-rle-3.3.0和dcm4che-imageio-3.3.0自动进行图像转换,对于JpegLoss格式的dcom图像不再有效。
正如我之前提到的,我们仍然可以使用dcm 3.3.0库。对于 例如,我们需要dcm4che-tool-storescp-3.3.0来接收二进制文件 listener和dcm4che-core-3.3.0获取dicom的属性 文件
<dependency>
<groupId>org.dcm4che</groupId>
<artifactId>dcm4che-core</artifactId>
<version>3.3.0</version>

<dependency>
<groupId>org.dcm4che.tool</groupId>
<artifactId>dcm4che-tool-storescp</artifactId>
<version>3.3.0</version>
</dependency>
第5步: - 如果发生此异常:没有类的图像读取器 com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageReader可用于格式:jpeg
然后j-imageio-1.0.01.jar的c-libs似乎不可用,但事实上它就是那里意味着api(jai_imageio-xx.jar)有时不足以在运行时被JVM看到。将clib_jiio.dll,clib_jiio_sse2.dll和clib_jiio_util.dll复制到C:\ Program Files(x86)\ Java \ jdk1.7.0 \ jre \ bin中对我来说都没有用。
解决方案:
从以下位置下载并运行jai_imageio-1_0_01-lib-windows-i586-jre.exe 这里:
注意:请选择C:\ Program Files(x86)\ Java \ jdk1.7.0 \ jre \ bin进行安装。 实际上它也将本机库复制到bin目录中,但由于某些原因,手动复制dll文件对我来说不起作用。也许它也会复制jar文件。
