带有 IKVM 的 FOP：无图像
我已经在.NET 中成功编译并使用了 FOP 1.0 和 IKVM 0.44.5，但是我无法让它在生成的 PDF 中显示任何图像。
当我在命令行中通过 ikvm 运行 FOP 时，出现 java.io.EOFException。当我使用 java 转换同一文件时，图像完美显示。

有人使用 FOP+IKVM 获取图像吗？任何帮助或指向解决方案的指示将不胜感激！
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.
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.

Has anyone gotten images to work using FOP+IKVM? Any help or pointers to a solution would be highly appreciated!

我对 FOP 不太了解，但是一个简单的图像示例就可以了：
这会生成一个看起来不错的 images.pdf 。
如果您有这样的重现场景，请随时将其邮寄给我 ([email protected ]）我会看看。
更新：感谢您提供导致问题的 .png。我用 0.44 重现了这个问题，但在当前的开发版本中它可以正常工作。最新的开发快照位于 http://weblog.ikvm.net/
I don't know much about FOP, but a simple example with images works:
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.
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/
