如何给网站做二维码,建设网站的规则,在上海做兼职在哪个网站好,wordpress地址怎么改背景#xff1a;
今天有个朋友找我#xff1a;“我有个文件需要更改#xff0c;但是文档是PDF的#xff0c;需要你帮我改下内容#xff0c;你是搞软件的#xff0c;这个对你应该是轻车熟路了吧#xff0c;帮我弄弄吧”#xff0c;听到这话我本想反驳#xff0c;我是开…背景
今天有个朋友找我“我有个文件需要更改但是文档是PDF的需要你帮我改下内容你是搞软件的这个对你应该是轻车熟路了吧帮我弄弄吧”听到这话我本想反驳我是开发不是美工然后跟他科普科普两者的分工和区别。后来想想还是算了隔行如隔山讲了可能也是白讲。干脆给他干了得了。毕竟这种类似“程序员修电脑的”印象在亲戚朋友中早已广为流传。
起因
一开始觉得做这个工作很简单打开WPS直接按他的要求编辑下就算完成就可以的可当我打开文档编辑的时候 呵呵这特么干个免费的活感情还要自己掏腰包
于是一个想法冒出来了把文档转成图片再用PS改得了于是我又尝试转换成图片 挣扎
我了个擦要点脸不也不知道啥时候起金山也养成了企鹅家的作风。于是我想想既然是帮人干活这个钱怎么也不至于我掏吧对让他掏可话又说回来就这么点屁事让人花几十上百也是有点坑。
既然WPS处处要花钱那就不用了自己写一个不就OK

转成图片修改好以后再给合回去60行代码换了100多的会员头一次感受到了原来技术也不是一文不值O(∩_∩)O哈哈~
输出
完事后想想这个东西既然花了时间写出来干脆加个界面打包成程序提供给有需要的人用岂不是更能发挥它的价值
说干就干
