【Python自制工具软件】批量图片转PDF小工具——PIC2PDF

楔子

大家在工作当中总会冒出各种各样的需求,尤其当面对繁琐的工作时。

“如果有那样一款想象中的工具就好了!”可以瞬间解决手头工作的想象中的工具,是否存在呢?

当然,然而获得它总是需要我们花费大量的时间去筛选甄别,有的充斥大量广告,有的则需要付出不菲的费用。

其实完全可以自己上手来实现自己想象出的功能,做出适合自己使用的软件。过程中也可以一步一步不停的完善,将它当作一款产品去打磨。

这样有成就感的事情,其实用Python实现起来非常简单。

正好这段时间有整理照片的需求,于是就诞生了这样一款小工具。

虽然市面上很多这样类似的软件,但是自己做出来的也许更适合自己的使用习惯。

现在将代码附上,如有需要可以自行借鉴修改。

所用第三方库均可使用 pip 进行安装

pip install pillow

pip install windnd

效果图

打包

如果想将其打包为单独的 exe 可执行文件可使用 Pyinstaller 通过以下命令实现

pyinstaller -F -w -i favicon.ico -n PIC2PDF main.py

安装 Pyinstaller

pip install Pyinstaller

创建虚拟环境

打包时请使用纯净的虚拟环境来减小打包后文件大小,可通过如下操作创建虚拟环境

在 Windows 系统下

1、通过 pip install virtualenv 安装创建虚拟环境所需要的第三方库

2、通过 virtualenv env_name 创建名为 env_name 的虚拟环境,虚拟环境将创建到当前目录下

3、激活虚拟环境:找到 env_name/Scripts/ 目录下 activate 执行,在命令行中,当前输入行前将会有 env_name 前缀表明已进入虚拟环境

4、在虚拟环境中通过 pip 安装 PyinstallerPILwindnd 成功后即可进行打包
