Question

我下载了库以处理EPS文件here

并编写一些代码来解析eps文件

    EPSImageReaderSPI spi = new EPSImageReaderSPI();
    EPSImageReader eps = new EPSImageReader(spi);

    File file = new File("file.eps");
    InputStream in = null;
    try {
        in = new FileInputStream(file);
    } catch (FileNotFoundException e) {
        e.printStackTrace();  
    }
    ImageInputStream iis = null;
    iis = ImageIO.createImageInputStream(in);
    eps.setInput(iis);
    eps.getHeight(0);

我的代码崩溃了

Exception in thread "main" javax.imageio.IIOException: Data type -1 not supported
at epsLib.EPSImageReader.readHeader(EPSImageReader.java:307)
at epsLib.EPSImageReader.getHeight(EPSImageReader.java:148)

你可以帮帮我吗？非常感谢！

更新：

当我尝试安装jmagick时，但是当我运行命令时

./configure --with-java-home=/System/Library/Frameworks/JavaVM.framework/Versions/Current --with-magick-home=/usr/local/Cellar/imagemagick/6.8.0-10 --with-magick-inc-dir=/usr/local/Cellar/imagemagick/6.8.0-10/include

得到错误

/usr/local/Cellar/imagemagick/6.8.0-10/bin/MagickCore-config: line 50: pkg-config: command not found

更新：

好的我修好了！只需将命令改为

./configure --with-java-home=/System/Library/Frameworks/JavaVM.framework/Versions/Current --with-magick-home=/usr/local/Cellar/imagemagick/6.8.0-10 --with-magick-inc-dir=/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/

然后我尝试

make all

并收到错误

make[1]: Entering directory `/Users/olegsuzaev/jmagick-6.4.0/src'make[2]: Entering directory `/Users/olegsuzaev/jmagick-6.4.0/src/magick'../../Make.rules:175: *** missing separator.  Stop.
make[2]: Leaving directory `/Users/olegsuzaev/jmagick-6.4.0/src/magick'
make[1]: *** [dir_target] Error 2
make[1]: Leaving directory `/Users/olegsuzaev/jmagick-6.4.0/src'

有人可以帮忙吗？ THX

我建议您联系此代码的作者或亲自查看代码，找出发生此异常的原因。

作为替代方案，似乎有许多可用于Java的EPS API。以下是一些：

此外，ImageMagick（一个C库）支持EPS读取EPS，还有一个名为JMagick的ImageMagick JNI包装器，允许从Java访问ImageMagick。

eps阅读器java
