Alfresco 3.4.e共享：大PDF文件预览不'；行不通

pdf encoding alfresco

Alfresco 3.4.e共享：大PDF文件预览不'；行不通,pdf,encoding,alfresco,pdf2swf,Pdf,Encoding,Alfresco,Pdf2swf,我的Alfresco 3.4.e股票申请有问题。当您上载一个文件（例如PDF文件）时，它的大小很大（在本例中为10MB），“通过浏览器预览文件”选项不起作用。窗口打开，文档正在处理中，然后崩溃。 当您尝试预览一个像1mb文件这样的小文件时，您不会遇到任何问题 我已经对这个问题进行了研究，显然，您可以修改“内容转换限制”。以下是我提到的文档的链接： 总之，您只需在“content services context.xml”文件和“thumbnail services context.xml”文件

我的Alfresco 3.4.e股票申请有问题。当您上载一个文件（例如PDF文件）时，它的大小很大（在本例中为10MB），“通过浏览器预览文件”选项不起作用。窗口打开，文档正在处理中，然后崩溃。 当您尝试预览一个像1mb文件这样的小文件时，您不会遇到任何问题

我已经对这个问题进行了研究，显然，您可以修改“内容转换限制”。以下是我提到的文档的链接：

总之，您只需在“content services context.xml”文件和“thumbnail services context.xml”文件中设置属性即可。 以下是您必须设置的属性：

  • 超时
  • readLimitTimeMs
  • maxSourceSizeKBytes
  • 可读极限KB
  • 页面限制
  • 最大页面
但是，这些属性都不存在，例如在类
“org.alfresco.repo.content.transform.magick.ImageTransformationOptions”或类中
“org.alfresco.repo.content.transform.TextToPdfContentTransformer”。
当这些属性设置为不可写时，我遇到了一个错误，我查看了源代码，发现它们根本不存在

我有另一个理论，在其中的文件是复杂的转换（超过100页，大量的图像和样式…）。
以下是文档转换和预览尝试后写入的错误日志：

如果查看日志，问题可能与
pdf2swf
有关，该问题由于高字节字符或特殊字符而崩溃

所以，如果你们有什么想法


提前感谢。
如果您回顾wiki的第一行，您会注意到属性限制适用于企业版3.4.8或4。我不确定它是否适用于3.4.d版。但是，无论如何，这不是重点。这些限制是在最新版本中创建的，以避免您从pdf2swf.exe中获得的错误，并将静态图像作为预览显示，这可能不如常规Flash预览漂亮，但至少可以为您提供预览。该功能可能在3.4d中不可用，尽管它可能在版本4中可用

您面临的真正问题是以下语句（为了可读性，我将其缩短了一点）：


您可能希望在命令行中输入该命令，然后看看会发生什么。如果出现错误，可能需要尝试不同版本的pdf2swf.exe。如果您没有收到错误，并且事情得到了很好的转换，那么您可能需要为Alfresco的Java堆分配更多内存（参数-Xmx），确保您有足够的硬盘空间，当然，您也有足够的物理RAM内存。
开箱即用安装不应该有任何转换限制，即使在您的版本中实现了这些限制。因此，除非您专门配置了限制，否则这不太可能是问题的原因

更有可能的是，
pdf2swf
根本无法处理您上传的文件。这似乎与您从日志中发布的堆栈跟踪一致，但请注意，Alfresco将截断错误流。如果您真的想看到完整的错误，那么接受它提供给您的命令，并在命令提示符下以交互方式运行它

您没有提到安装了哪个版本的SWFTools，但这将是一个很好的起点。您可以尝试更新的版本或SVN快照，看看这是否有帮助

最后，您还可以更改传递给
pdf2swf
的命令行参数，不过您需要做一些研究，以了解哪些参数最适合要上载的内容类型

以下默认设置在alfresco webapp内部的文件
alfresco/subsystem/thirdparty/default/swf transform.properties
中设置，但您可以在自定义的
alfresco global.properties
文件中覆盖它们


# This option on pdf2swf improves the transformation of graphics-heavy pdfs. See ALF-3580.
# poly2bitmap improves the chances of successful transformation. On its own it reduces
# the resolution of embedded images. subpixels sets the dpi for embedded images.
# zoom introduced and -s added before each option (ALF-9417).
swf.encoder.params=-s zoom=72 -s ppmsubpixels=1 -s poly2bitmap=1 -s bitmapfonts=1


评论中提到的问题也可能引起关注。
好

首先，谢谢你的回答！
这真的帮了我很大的忙

事实上，问题来自
pdf2swf
。Alfresco的默认配置不适用于大型PDF文件。我拥有的一个包含太多的富字符，因此“swf transform.properties”的默认参数配置为：

替换为：


swf.encoder.params=-s zoom=72 -s ppmsubpixels=1 -s poly2bitmap=1 -s bitmapfonts=1 


现在我可以毫无问题地预览我的大PDF文件了


再次感谢您的帮助。
旁注：请不要使用3.4.e社区。稳定的3.4社区版本是3.4.d。3.4.e是Activiti集成的“预览”版本。谢谢，我已经按照您的建议修改了配置，效果很好。我已经用我目前的配置回复了这篇文章。谢谢，这确实是配置不符合我的需要。我的答案上有我的新配置。

swf.encoder.params=-s poly2bitmap,subpixels=72



swf.encoder.params=-s zoom=72 -s ppmsubpixels=1 -s poly2bitmap=1 -s bitmapfonts=1
