问题描述
我已经在.NET中成功编译并使用FOP 1.0和IKVM 0.44.5，但是无法在显示的PDF中显示任何图像.
I've successfully compiled and used FOP 1.0 with IKVM 0.44.5 in .NET, however I can't get it to show any images in the resulting PDF.
当我在命令行中通过ikvm运行FOP时，我得到了java.io.EOFException.当我使用Java转换相同的文件时，图片会完美显示.
When I run FOP via ikvm in the command-line, I get a java.io.EOFException. When I transform the same file using java, the Images shows up perfectly.

有人使用FOP + IKVM使图像工作吗?任何帮助或指向解决方案的指针将不胜感激！
Has anyone gotten images to work using FOP+IKVM? Any help or pointers to a solution would be highly appreciated!
推荐答案
我对FOP不太了解，但是一个简单的带有图像的示例有效:
I don't know much about FOP, but a simple example with images works:
C:\j\fop-1.0>set JAVACMD=\ikvm-0.44.0.5\bin\ikvm.exe
C:\j\fop-1.0>fop -fo examples\fo\basic\images.fo -pdf images.pdf
这将导致images.pdf看起来不错.
This results in an images.pdf that looks good.

If you have a repro scenario for this, feel free to mail it to me ([email protected]) and I'll have a look.
更新:感谢引起问题的.png.我用0.44重现了该问题，但是在当前的开发版本中，它可以正常工作.最新的开发快照可从 http://weblog.ikvm.net/
Update: Thanks for the .png that caused the problem. I reproduced the problem with 0.44, but in the current development version it works correctly. The most recent development snapshot is available at http://weblog.ikvm.net/
