# 我将手稿上传到期刊投稿门户时，EPS 或 PDF 图像文件中的文本缺失了，但在 Overleaf 上看起来一切正常

根据投稿门户技术支持的反馈，这很可能是由于已上传的 EPS/PDF 文件中存在多层所致。（TIFF 和 PNG 文件也可能会出现这种情况。）

在与稿件文件一起提交之前，通过将 EPS/PDF 文件扁平化，通常可以避免此类问题。这样会将图像的所有图层合并为单一图层，并且没有 alpha 通道。

Photoshop 和 [GIMP](https://www.gimp.org/)，以及一些其他图像处理程序，都包含此类“扁平化图像”或“合并图层”功能。你也可以使用命令行命令，例如 [ImageMagick](http://www.imagemagick.org/Usage/layers/#flatten)，或者使用 `epstopdf` 和 `pdftops` 进行往返转换。例如，对于名为“fig1.pdf”的 PDF 图像，运行：

```
pdftops -eps fig1.pdf
```

以生成 .eps 文件，然后

```
epstopdf fig1.eps
```

以得到一个扁平化的 .pdf。

如果在尝试这些步骤后，您的图像仍然存在问题，请 [联系我们](https://www.overleaf.com/contact) 联系我们，我们会看看是否能提供帮助。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-cn/zhi-shi-ku/135-the-text-in-my-eps-or-pdf-image-file-is-missing-when-i-uploaded-my-manuscript-to-a-journal-s-sub.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
