How To Add Multiple PDF Pages as Figures / Images / Graphics

To include multiple pages can be tedious, as the includegraphics command has to be adjusted for every page (page=1, page=2, page=3,...). Instead, I wrote a short program in C that creates the tex-code that can then be inserted into the LaTeX document:

#include <stdio.h>
int a=0, b=0, i=0;

int main()
{
    FILE *f = fopen("myfile.tex","w");
    for (i=1 ; i<b+1 ; i++)
    {
        fprintf(f,"includegraphics[width=textwidth,page=%d]{document.pdf}nn",i);
    }
    return 0;
}

This creates a file myfile.tex with the includegraphics[width=textwidth,page=1]{Document.pdf} followed by a double line break for the pages 1 to b (so b should be the number of the last page you want to include, just change it in the second line (int a=0, b=0, i=0;)). Also, change the part saying {document.pdf} to the name of the PDF you want to include (the name you would tell LaTeX).

Once you changed b to the last page you want to include, and {document.pdf} to the appropriate name/location for LaTeX, you can save this file, e.g. as write.c (the ending .c is important here, as it is a program written in C).

Then, open a terminal and go to the file location, e.g.

cd ./MyCodeFolder

make sure that you are in the right folder and that your write.c-file is there:

ls

lists all files in the current folder. If so, compile it, to get a executable program:

gcc write.c -o write.exe 

gcc is the compiler, write.c the source code we just created, and write.exe the program that will get created by the compiler after hitting enter.

Now, execute write.exe. This creates myfile.tex. Final step: Go to you LaTeX code, make sure Document.pdf is there as well, add myfile.tex and include it where you want your PDF pages in your LaTeX document using

input{myfile.tex}

Profit.
