我需要将多页PDF转换为TIF，但它似乎是由我们的客户提供的格式错误的PDF。我尝试使用ImageMagick和GhostScript，但它们没有正确转换文件。结果只有大约85-90％的正确率。我发现似乎唯一能做的就是GIMP，但我找不到一个例子来通过PDF的批量处理方法来使用它。
以下是我从ImageMagick和GhostScript获得的警告：

我也对其他建议持开放态度。谢谢！

就无法发表任何实质性评论。你有没有考虑过简单地发回文件并告诉他们做一个合适的文件？
另外，您没有说明您正在使用的GS和ImadeMagick版本。

破碎的PDF ...我“爱”他们。实际上，一个奇怪但好的想法是，将pdf“打印”到另一个pdf或ps文件中。这可以帮到很多。
