在Qt中调用Mupdf库进行pdf显示

2018.5.10 更新内存对齐说明 感谢知乎网友 @ 孤独子狮 指出QImage处需要考虑内存对齐的问题。因为本人缺乏跨平台、图形库开发经验，所以在调试成功后就没有深入探究。 主要修改了QImage的构造方式，使用了指定 bytesPerLine的构造函数，具体原因参见 孤独子狮的回答 - 知乎 https://www.zhihu.com/question/38594052/answer/387891545 前言 最近有个pdf的需求，Qt竟然没有显示pdf的api，着实令人郁闷。之后我尝试用了poppler，但是光配置编译工程就相当麻烦了，没有cmake等开源项目编译经验的人完全一脸懵逼。PDFium也是同理（手头上没有vpn也无法尝试）。感觉Mupdf编译器起来比较简单，所以就来用了一下。不过这个库有个缺点就是编译出来的文件太大了。 本人使用的版本是Mupdf1.12.0+Qt5.9.3+vs2015 下载Mupdf库 https://mupdf.com/downloads/ 编译Mupdf 在mupdf-1.12.0-source\platform\win32目录下就有现成的mupdf.sln。 这里需要注意：这个工程默认使用的是/MT，而Qt MSVC默认用的是/MD,所以需要修改编译工程设置。我们这里只需要在编译工程中修改就可以了。
