CHM to PDF conversion

Question

How to convert chm files to pdf?

Update (new answer)

sudo apt-get  install  chm2pdf

Then:

chm2pdf [--book | --webpage | --continuous] file.chm

Answer (old)

Step 1

First, we need to extract the compressed HTML files from the chm file.

$ sudo apt-get  install  libchm-bin
$ extract_chmLib  book.chm  outdir

For GUI junkies there is a more easy method. Open kchmviewer or install it (sudo apt-get install kchmviewer), then File → Extract chm content…, and select the destination folder.

Step 2

We will need the htmldoc program to group HTML files together and export them in a pdf file.

$ sudo apt-get  install  htmldoc

Then start htmldoc.

If the order of HTML files is not correct, then:

• Click on Save As…, and save it to a file, e.g. file.book.
• Open file.book with your favorite text editor (e.g. vim), and change the order of HTML files. (You could also do it in htmldoc, but that'd be too slow.)
• When done, open the corrected file in htmldoc and click on Generate.

That's all.
