找了很久也没有解决，求助
我今天也遇到了这个问题，找到了解决方法；
看我的博文：https://blog.csdn.net/qq_36299991/article/details/128185698
——————分割线——————
按照报错日志，文件资源管理器路径下没找到这个字体文件；
然后去百度找这个字体想安装上，找了一圈也没找到，也没看到啥有关的文章；
谷歌看看，找到了些有价值的问答；
https://stackoverflow.com/questions/67588149/pdfbox-eofexception-null-when-setting-textfield-value?newreg=4b300bf7c00643c3b2d49957be6e50b4
PDFBox的官网也有bug记录；
https://issues.apache.org/jira/browse/PDFBOX-5095
按照他们的对话描述，网上找到mstmc.ttf打开看不太像是字体文件，或者这个字体文件已经损坏，explorer.exe文件资源管理器把这个文件忽略了所以看不到，直接使用CMD去这个路径下看看：
Microsoft Windows [版本 10.0.19044.2251]
(c) Microsoft Corporation。保留所有权利。
C:\Users\Administrator>cd /windows/fonts
C:\Windows\Fonts>dir /s mstmc*
驱动器 C 中的卷是 系统
卷的序列号是 0284-E676
C:\Windows\Fonts 的目录
2022/05/04 02:05 4,096 mstmc.ttf
1 个文件 4,096 字节
C:\Windows\Fonts>copy mstmc.ttf d:\
C:\Windows\Fonts>del mstmc.ttf
已复制 1 个文件。
于是我把这个文件备份到D盘根目录，然后把当前的删掉了，再次运行程序就解决了；
可以试一下Free Spire.PDF for Java，代码挺简单的，可以参考这篇文章
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import com.spire.pdf.PdfDocument;
import javax.imageio.ImageIO;
public class toImage {
public static void main(String[] args) throws IOException {
//加载PDF文件
PdfDocument doc = new PdfDocument();
doc.loadFromFile("Sample.pdf");
//保存PDF的每一页到图片
BufferedImage image;
for (int i = 0; i < doc.getPages().getCount(); i++) {
image = doc.saveAsImage(i);
File file = new File( String.format("ToImage-img-%d.png", i));
ImageIO.write(image, "PNG", file);
}
doc.close();
}
}
import java.awt.image.BufferedImage;
