前言

云曦Convert软件主要采用C++、Python、Html等语言编写,以Qt5.11.1和Pycharm为编译器,运用DJANGO框架和相关QT模型与算法,以Python为后端,Qt为前端,前后端结合,为用户提供PDF文件合并,选择拆分,平均拆分以及语音导航等功能,实现用户对PDF编辑更加多样化的需求。


一、云曦Convert效果图 1. 回到首页:

在桌面上双击系统的图标就会出现以下的界面,这时候就会d出了应用首页的界面,从这个界面中可以看到本软件所提供的相关功能和注意事项,如需在连网情况下适用等,如果不连接网络,将无法正常使用该软件,详情如下图1-1所示:

2. 选择拆分:

点击选择拆分按钮,将所需要拆分的文件拖入提示框中,如图2-1所示,然后输入要拆分的页数范围,点击拆分即可,详情见下图:


3. 平均拆分:

具体 *** 作同选择拆分,点击平均拆分按钮,将所需要拆分的文件拖入提示框中,如图2-4所示,然后输入要平均拆分的页数,点击拆分即可,详情见下图:




4. 文件合并 :

同上述功能 *** 作,点击文件合并按钮,将所要合并的文件拖入框中,输入合并后的文件名,点击合并,合并后打开即可,如图2-9所示。

5. 语音助手:

点击界面右上方类似于耳机的按钮,即可召唤出语音助手,来为您讲解我们的项目。如下图所示,该功能详细代码解析点击此处:
