转word后图片被旋转180°

[liuts-plane]

您好，在提出这个问题之前，我已经看过了其他issue，比如：#110

问题描述：
我使用command将pdf转成word时，所有的图片发生了180°的旋转，使用的命令：pdf2docx convert ./iso66.pdf iso66.docx

问题pdf：
iso66.pdf

我的本地版本：

非常感谢您百忙之中的解答！

[heweisheng]

看看 #292 的fix方案能用不

[liuts-plane]

谢谢回复！！！

result:
还是旋转的180°，我的流程如下：

pip3 uninstall pdf2docx
pip3 install git+https://github.com/ArtifexSoftware/pdf2docx.git@jules

根据历史issue，这个问题看起来还很难解决,您有空了再说吧

为了确保pip没问题，然后我又尝试：pip install git+https://github.com/ArtifexSoftware/pdf2docx.git@98e92cb40c3f45dba7abd18f1cbac4171ee40e0c
报同样的错

我改的东西也不多吧...你直接安装完后在库里改掉看看不就ok了吗，而且提交还没有被合并，为啥你从主库拉呢

[liuts-plane]

谢谢

非常有效！！！

我的方案不是很好，但是矩阵变换玩不通，另外源码还有问题就是png会丢失透明度，还需要处理

[yanhuixie]

@heweisheng 多谢兄弟，我也遇到一样的问题，不过不是所有图片，而是部分图片被旋转90°，使用你的PR可以解决。

我现在发现还有些细节要处理下，有个印章的旋转不是90倍数的，这个方案有问题，我还在修改中

[heweisheng]

#298 完善了矩阵变换的流程，你们可以测试下有问题不，我这里把印章的效果解决了,修复了png丢失透明度的bug，自测了下所有的exif情况没有什么问题，虽然逆矩阵的原因没有弄明白，但是能跑出预期的数据了 @yanhuixie @liuts-plane

多谢兄弟，赞神速~
我这边的文档比较简单，您上一个版本就解决问题了。
我这边在尝试pdf2docx，可能不会选用，效果目前还满足不了，主要是在文本流布局和表格的解析方面。

Images may internally contain rotation (EXIF information). We need to check the image insertion matrix and appropriately reverse this action before outputting to word.
