# 我將手稿上傳到期刊投稿入口後，我的 EPS 或 PDF 影像檔中的文字消失了，但在 Overleaf 上看起來一切正常

根據投稿入口技術支援的回饋，這很可能是由於您上傳的 EPS/PDF 檔案中包含多個圖層所造成。（TIFF 和 PNG 檔案也可能會發生這種情況。）

這類問題通常可以在將 EPS/PDF 檔案與手稿檔一起提交之前，先將其扁平化來避免。這會將影像的所有圖層合併為單一圖層，且沒有 alpha 通道。

Photoshop 和 [GIMP](https://www.gimp.org/)，以及其他一些影像處理程式，都包含這類「扁平化影像」或「合併圖層」功能。您也可以使用命令列指令，例如 [ImageMagick](http://www.imagemagick.org/Usage/layers/#flatten)，或使用 `epstopdf` 和 `pdftops` 來進行往返轉換。例如，對於名為「fig1.pdf」的 PDF 影像，請執行：

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

以取得 .eps，然後

```
epstopdf fig1.eps
```

即可再轉回扁平化的 .pdf。

如果在嘗試這些步驟後，您的影像仍然有問題，請 [與我們聯絡](https://www.overleaf.com/contact) 我們會看看是否能幫上忙。

# 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-tw/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.
