![我的 PDF 阻止我的觀眾使用滑鼠](https://rvso.com/image/328250/%E6%88%91%E7%9A%84%20PDF%20%E9%98%BB%E6%AD%A2%E6%88%91%E7%9A%84%E8%A7%80%E7%9C%BE%E4%BD%BF%E7%94%A8%E6%BB%91%E9%BC%A0.png)
PDFTeX 將我的文件排版為兩欄。不幸的是,當一個人打開 PDF 時,PDF 不會讓該人的滑鼠從一列中拾取文本,而是從左到右交錯文本,這是沒有意義的。
為了顯示:
Here is some text Here is some text
in the left column. in the right column.
It speaks of It speaks of
leftward things. rightward things.
該人對左側文字感興趣,嘗試用滑鼠突出顯示它(例如,可能將其複製到電子郵件中)。遺憾的是,他的滑鼠得到的結果是這樣的:
這是一些文字 這是左欄中的一些文字。在右欄。它談到了它談到了左翼的事情。向右的事。
可以理解,這會惹惱我的觀眾。
解決方案?
更多資訊
我在模式下使用 LaTeX 的report
類別\twocolumn
。使用的軟體包可能與我的問題無關,但恰好是這些:ifthen;圖形x;阿姆斯數學;標題;超級參考。
我不知道我的問題是 TeX 問題、LaTeX 問題、DVI 問題(但 PDFTeX 甚至使用 DVI 嗎?)還是 PDFTeX 問題。實際上,我不認為這是 PDFTeX 問題,因為即使我使用latex
anddvipdf
代替 ,也會出現問題pdflatex
。
我的聽眾對 TeX 知之甚少或一無所知,因此向聽眾提供我的 LaTeX 原始碼並沒有什麼好處。滑鼠問題只會讓他們抱怨我應該使用 Microsoft Word——顯然,我寧願不這樣做。
更新
PDF 閱讀器 Evince 的開發人員特意來到這裡發表評論。他還沒有發布回答如此,但他的評論非常值得一讀。您可以在這個問題和下面接受的答案下找到他的評論,名為@gpoo。
(由於回答者指出他更喜歡其他軟體,所以我應該指出,我自己更喜歡 Evince。事實上,即使我不使用 GNOME,我也使用 Evince,而 Evince 通常與 GNOME 相關。)
例子
下面是一個無聊的例子。如果將其編譯為 PDF,打開 PDF,並嘗試用滑鼠從左欄中複製文本,則不起作用。為什麼不?

這是觀眾的問題。正如您所期望的,Adobe Reader、Skim 和 Preview 都會選擇第一列。我只能用舊版的 Evince 和 Okular 重現問題。我沒有這兩個檢視器的最新版本,但 @Christian Hupfer 和 @gpoo 測試了 Okular 和 Evince 的最新版本,發現它們都可以工作。由於其他原因,我早就得出結論,永遠不應該使用 Evince。自 Windows 95 以來,我還沒有見過如此頻繁崩潰的軟體。
