swftools工具时，转换大文件ERROR This file is too complex to render- SWF only supports 65536

if the pdf contains too many images / shapes, pdf2swf will fail with this error :

ERROR This file is too complex to render- SWF only supports 65536 shapes at once

There is a very simple fix : add “-s poly2bitmap” to the options given to the transformer’s commandMap in swf-transform-context.xml

The issue is also discussed in ETHREEOH-3023 , and it can be easily reproduced with the pdf attached to ETHREEOH-3023 .
With the added options “-s poly2bitmap” (which means converts pdf graphics to bitmaps) allows the transformation to complete successfully, so maybe we could add this option by default.

Cheers,

上面是在使用swftools工具时，转换大文件时发生了一个怪现象：我先将大文件word转为pdf，再将pdf转为swf，由pdf转换为swf过程中，竟然没有输入转换后的swf文件，后来用命令行来转换一下，才知道那个pdf文件太大了，所以转换时发生了异常：

ERROR This file is too complex to render- SWF only supports 65536 shapes at once 

处理这个问题可以按上面的方法，在转换时加入参数-s poly2bitmap来将文件中的图形转成点阵，这个是由于文件大太或者文件图形过多而引起的异常，所以我在转换的过程时加入了文件的大小的判断，当文件过大时，就加入这个参数，不然就直接转，因为我测试的时候，不加入这个参数时，转换的速度快一点。
