如何将两个PDF页面拼接成一个大页面? [英] How to stitch two PDF pages together as one big page?

问题描述

我有两个36英寸乘48英寸的海报(LaTeX)，我想将它们附加到单个72英寸乘48英寸的海报中(垂直堆叠).

I have two 36" by 48" posters (LaTeX) that I want to append into a single 72" by 48" poster (stack vertically).

浏览SO和GS文档，我一无所知(我不是CLI向导).我该怎么办?

Browsing around SO and GS documentation, I have no clue (I'm not a CLI wizard). How can I do this?

(此外，该过程也不应有损地压缩光栅图像，因为它将以2400 * 1200 DPI的分辨率打印.)

(Also, the process should not compress the raster images lossily, because this will be printed 2400*1200 DPI.)

推荐答案

由于OP没有提供原始输入张贴者(指向其的链接)，因此该回答将分三步进行:

Since the OP didn't provide (a link to) the original input posters, this answer will proceed in three steps:

1. 创建2个虚拟海报作为第3步的输入
2. 创建一个嵌入2个虚拟海报的LaTeX文档
3. 运行pdflatex在步骤2中从LaTeX文档创建PDF

1. Create 2 dummy posters as input for step 3
2. Create a LaTeX document which embeds the 2 dummy posters
3. Run pdflatex to create a PDF from the LaTeX document in step 2

步骤1:创建2个虚拟海报(大小为36in x 48in)

我创建了两个不同的PDF虚拟海报，向您展示如何使用 LaTeX . (这意味着:您至少需要在系统上安装基本的LaTeX，包括pdflatex实用程序.)

Step 1: Create 2 dummy posters (with size of 36in x 48in)

I've created two different dummy posters as PDF to show you how to do it with LaTeX. (That implies: you need to have at least a basic LaTeX installation on your system, including the pdflatex utility.)

这两个假人是我在Ghostscript的帮助下创建的.由于对于Ghostscript的pdfwrite设备1in == 72pt == 720pixels，命令是这样的(因为36in == 2592pt == 25920pixels和48in == 3456pt == 34560pixels):

These two dummies I created with the help of Ghostscript. Since for Ghostscript's pdfwrite device 1in == 72pt == 720pixels, the commands are like this (because 36in == 2592pt == 25920pixels and 48in == 3456pt == 34560pixels):

gs -o poster1.pdf                   \
   -g25920x34560                    \
   -sDEVICE=pdfwrite                \
   -c " /Helvetica-Bold findfont"   \
   -c " 500 scalefont"              \
   -c " setfont"                    \
   -c " 50 2000 moveto"             \
   -c " (POSTER 1) show"            \
   -c " 1 0 0 setrgbcolor"          \
   -c " 10 setlinewidth"            \
   -c " 20 20 2552 3416 rectstroke" \
   -c " showpage" 

gs -o poster2.pdf                   \
   -g25920x34560                    \
   -sDEVICE=pdfwrite                \
   -c " /Helvetica-Bold findfont"   \
   -c " 600 scalefont"              \
   -c " setfont"                    \
   -c " 50 2000 moveto"             \
   -c " (Poster 1) show"            \
   -c " 1 0 0 setrgbcolor"          \
   -c " 10 setlinewidth"            \
   -c " 20 20 2552 3416 rectstroke" \
   -c " showpage" 

以下是显示这些海报"的2个屏幕截图:

Here are 2 screenshots showing these "posters":

有一个名为'pdfpages'的LaTeX软件包，它可以将PDF页面插入LaTeX文档，但也可以从PDF页面创建"n-up"布局. (除了基本的LaTeX安装外，您还需要该软件包.)

There is a LaTeX package called 'pdfpages' which can insert PDF pages into LaTeX documents, but which also can create "n-up" layouts from PDF pages. (In addition to your basic LaTeX installation you need that package too.)

这是您可以使用的小型LaTeX程序.将其另存为2up-poster.tex:

So here is a small LaTeX program you can use. Save it as 2up-poster.tex:

\documentclass{article}
\usepackage{pdfpages}
\usepackage[paperwidth=72in, paperheight=48in]{geometry}
\pagestyle{plain}                                 % Don't use page numbers

\begin{document}
      \setlength\voffset{+0.0in}                  % adj. vert. offset as needed
      \setlength\hoffset{+0.0in}                  % adj. horiz. offset as needed
      \includepdfmerge[nup=2x1,
                       noautoscale=true,          % set "false" if larger inputs
                       frame=false,               % set "true" for frames
                       templatesize={36in}{48in}] % adjust as needed
                       {poster1.pdf,poster2.pdf}  % modify for file names
\end{document}

步骤3:运行pdflatex

现在，您可以运行以下命令来创建撰写的海报:

Step 3: Run pdflatex

Now you can run the following command to create your composed poster:

pdflatex 2up-poster.tex

这将创建一个名为2up-poster.pdf的PDF文件.

This will create a PDF file named 2up-poster.pdf.

结果在这里是屏幕截图:
