Ghostscript字體轉換問題

Question

全部，

我遇到了pdf中字體的問題。在原文中，它顯示了一條實線，但是如果我複製它，我會在剪貼板上獲得這個ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ。

這表明它是一些特殊的字體被使用，這會很好。問題是我使用這個pdf作爲ghostscript的輸入，並且該行變成了一堆帶有X的框。

經過一番搜索，我碰到this answer。 -c命令成功刪除了這些框，但該行仍然缺失。

運行在Windows gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf USA_15238-2897_5853101.pdf 7 64位系統，我得到下面的輸出：

添加Windows字體文件夾的字體路徑開關允許查找字體，但不能解決行盒問題。

運行gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf -c ".setpdfwrite <</NeverEmbed [ ]>> setdistillerparams" -f USA_15238-2897_5853101.pdf產生這樣的：

但現在該行是在PDF空間。如果我複製並粘貼它，我會得到─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─。

我需要添加哪些ghostscript開關以保持原始PDF格式的行？

Answer 1

沒有看到您的PDF文件就無法說出發生了什麼。請注意，在Ghostscript轉換爲PDF後，複製+粘貼並不能保證能夠正常工作，尤其是。

既然你已經有一個PDF文件，爲什麼你把它轉換爲PDF？

最可能出現的問題是將信使換成信使 - 新的，但沒有看到文件我不能確定。
