I have a lot of image files. I want to convert them to one single pdf file. How can I do it?
First, install imagemagick:
sudo apt-get install imagemagick
Then in the images folder, do something like:
convert *.png out.pdf
Maybe you can do
convert * out.pdf.(I didn' t try this one). Otherwise, You can convert other images to png first then do above. For more details see doc of imagemagick convert command.
