Has anybody heard of this cool command line program for Linux, that you can use to convert the formats of images with a single command, and even convert images to PDFs? Great for taking screenshots and converting the PNGs to PDFs so you can quickly include them in your research papers?
The program is called imagemagick, and it can be installed on Ubuntu with a simple
$ sudo apt-get install imagemagick
Then, to convert a file, just do
$ convert file.png file.pdf
And voilá! It works. Neat, eh?
