将png、jpg图片转为eps格式

我是靠谱客的博主潇洒紫菜，这篇文章主要介绍将png、jpg图片转为eps格式，现在分享给大家，希望可以做个参考。

由于要写论文，如Elsevier中对图片的要求如下：只能是eps或jpg，对于jpg的要求也太多了吧，所以干脆全部搞成eps得了，但是如何操作呢，下面就详细介绍。

首先说一个错误做法：有的小伙伴直接将图片后缀改了，这个是不对的，虽然你可以打开，但是LaTeX不能识别

对于要将图片格式转为eps的，基本都是在LaTeX中写论文需要的，所以这里默认你已经安装了LaTeX环境，这种方法就是利用latex已经提供的工具 bmeps，不需要你额外下载或安装任何软件。具体步骤如下：
1、通过打开cmd（在电脑下方直接搜索即可，或者win键+r，然后搜索cmd），输入：
在这里插入图片描述

bmeps -h

这时就可以查看当前安装的版本信息和操作，如下所示：

-p <pslevel>           select one of the following
         1                   (PS level 1)
         2                   (PS level 2 = default)

         8                   ASCII-85-encoding instead of ASCII-Hex
         r                   runlength encoding
         f                   flate encoding

         png
         jpg
         pnm

-d                     draft mode only
         Draft mode means the program reads only header information
         from the bitmap file and prints a dummy image.

-a <alphaoptions>
         o                   alpha channel is opacity, not transparency
         t                   alpha channel is transparency, not opacity
         l                   alternated transparency trigger level

         sd,d,d              specify background color i.e. s128,128,255
         PNG supports transparency channels, having values from
         0 ... 2^n-1. EPS supports simple yes/no decisions to mask
         pixels, so the alpha channels value must be mapped to
         "use pixel" or "mask pixel". The standard behaviour is
         to mask only pixels which have no opacity at all.
         The alternated trigger level uses only pixels having full
         opacity.
