无损合并PDF（PHP） [英] Lossless merging of PDFs (PHP)

问题描述

目前，我正在使用 ImageMagick 将多个PDF合并到一个PHP脚本中Linux系统。但是，生成的PDF质量非常低。我偶然发现了 pdftk ，它在合并后似乎有更好的质量，但我需要如果可能的话，使用ImageMagick，因为我需要让脚本在另一台没有pdftk的服务器上运行（并且在那里使用它会很痛苦。）

Currently I am using ImageMagick to merge multiple PDFs into one in a PHP script on my Linux system. However, the resulting PDFs are of very low quality. I have stumbled across pdftk which seems to have a better quality after the merging, but I need to use ImageMagick if possible because I need to get the script to run on another server which does not have pdftk (and it would be a pain to get it on there).

如何使用ImageMagick和PHP合并无损质量的PDF？

How can I merge PDFs using ImageMagick and PHP with lossless quality?

推荐答案

ImageMagick无法进行无损PDF合并。如果您有Linux服务器，您可以尝试pdfconcat（它可以非常快速地进行无损合并）：

ImageMagick can't do lossless PDF merging. If you have a Linux server, you may try pdfconcat (which does lossless merging very quickly):

$ wget -O pdfconcat http://www.math.bme.hu/~pts/cvsget.cgi/u=bin.i386/p=/M=bin.i386/c=f1/n=/bin.i386/pdfconcat
$ chmod +x pdfconcat
$ ./pdfconcat -o output.pdf input1.pdf input2.pdf input3.pdf
