我正在运行以下代码以使用Ghost4j从pdf创建bmp图像

我有一个逗号,由GhostScript生成器执行以从pdf生成页面的Bmp图像。
代码是:

package ghost;

import net.sf.ghost4j.Ghostscript;
import net.sf.ghost4j.GhostscriptException;

public class GhostDemo {
public static void main(String[] a){
    Ghostscript gs = Ghostscript.getInstance(); //create gs instance
    String[] gsArgs = new String[10];/*command string array*/
    gsArgs[0] = "-dUseCropBox";/*use crop box*/
    gsArgs[1] = "-dNOPAUSE";
    gsArgs[2] = "-dBATCH";
    gsArgs[3] = "-dSAFER";
    gsArgs[3] = "-r300";
    gsArgs[4] = "-sDEVICE=bmp16m";
    gsArgs[6] = "-dTextAlphaBits=4";
    gsArgs[5] = "-sOutputFile=C:/PagesWorkspace/1/masterData/1.bmp";/*bmp file location with name*/
    gsArgs[6] = "C:/MasterWorkspace/pipeline.pdf";/*pdf location with name*/

    try {

        gs.initialize(gsArgs);  /*initialise ghost interpreter*/
        gs.exit();

    } catch (GhostscriptException e) {
       e.printStackTrace();
    }
}
}

我收到异常
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'gsdll32': The specified module could not be found.

    at net.sf.ghost4j.Ghostscript.initialize(Ghostscript.java:292)
    at ghost.GhostDemo.main(GhostDemo.java:22)

谁能告诉我为什么我得到这个异常(exception)?

最佳答案

您是否已经安装了Ghostscript?

  • 如果是,哪个版本?
  • 如果可以,在哪个位置?
  • 它是否包含文件gsdll32.dll

  • 如果不是,请运行download the Ghostscript installer for Win32并运行它。安装后,目录gsdll32.dll中应该有一个%your_install_dir%\gs\gs9.05\bin\文件
