我读过类似这样的帖子如何减小 .eps 文件的大小？，Eps 文件太大[关闭]，Sun life：Linux：如何减小 eps 文件大小？但发现几乎没有什么可以帮助我解决问题。
Sun life：Linux：如何减小 eps 文件大小？这可以用于我的论文中的一些图表，但不能用于全部，正如评论中提到的那样。
所以我首先上传我的mange.tex代码，因为我用它来组合所有子图。
这是所需的vector.eps：
% Rusting Iron
% Author: Jason Waskiewicz
% A "jazzy" picture of the stages of rust (presented for a high school level).
% Iron is red, oxygen is blue and electrons are black. At the left you see
% iron atoms with two oxygen molecules, then the electrons go to the oxygen molecules
% leaving oxygen ions and iron ions which then disolve.

这将创建一个 PDF 图形，然后我使用
pdfcrop --margins '0 0 -908 0' mange.pdf output.pdf
得到最终结果是这样的：
我在这里提供：输出.pdf 523.kB
但我需要将此 pdf 转换为 eps，因此我使用以下命令：
pdftops -eps output.pdf
生成的eps文件如下：
pdftops -eps output.pdf
我在这里提供：输出.eps 2.3MB
但现在我需要根据出版物的要求进一步将 eps 格式的大小缩小到 500 ~ 800 kB。
所以我怎样才能实现这一点呢？
基本上我有两种想法：
- 直接缩小 eps 文件，就像这篇文章一样主题：调整 Eps/ps 文件大小但我对最后提到的方法感到困惑，例如
使用它打开 EPS 文件并在 EPS 标题后添加以下行（其中 sx 和 sy 是将图像重新缩放到所需大小所需的因子值）。
按照这个想法，我使用 GIMP 来缩放 eps 文件，但我觉得这会损害图形的质量。真可惜！
- 我直接在 Tikz 中将图形转换为 eps，因此我查看了类似的帖子从 TikZ 导出 eps 图形，使用 pdfLaTeX 将 TikZ 转换为 EPS但这似乎使问题更加复杂。这就是我提供 Tikz 代码的原因。
有什么想法吗？我该怎么办？
谢谢你！

谢谢成本加运费的建议我试过了但是效果似乎很奇怪如下图所示：
为什么颜色看上去这么淡？
