zypper install libchm-bin
chmlib allows extracting HTML files and images from (.chm) files. Now if you want to convert extracted HTML files into PDF, PS etc , you would need to install htmldoc which you could install easily by issuing the following command in the terminal window :
zypper install htmldoc
Converting CHM files to HTML and eventually PDF
Now suppose you have a file named "Primer.chm" from which you want to extract HTML files and images into "Primer" directory , you could do so easily by issuing the following command in the terminal window :
extract_chmLib Primer.chm Primer
This should quickly extract all the HTML files and associated images from the chm file and put it into Primer directory.
Open terminal and execute cmd “htmldoc”.
Once htmldoc finishes loading its interface ,click on Continuous radio button and press "Add Files…" and add all the files you would like to combine into single PDF document, as
shown in image below :
After choosing all the HTML files you would like to combine , click on the "output" tab and chose output file type to be PDF and the name and location of the finally generated PDF file.If you want you could change compression level , whether you want output to be in Grayscale etc
Finally press the "Generate" button to actually start the process of combining (.html ) files with their images into single (.pdf) file
The entire process of combining (.html) files into (.pdf) files should not take more than few minutes , infact on my Core 2 Duo based laptop entire process of combining about 1000 page long book in HTML format to PDF format took 4 minutes.
