Tiff and PDF Conversion Commands

Extracting PDF Files to Images

PDF files that contain a single image are often a pain to work with, but it is simple to extract that image using pdfimages.

First, run pdfimages with the list command to check the document is composed of a single image:

$ pdfimages -list file.pdf
page   num  type   width height color comp bpc  enc interp  object ID x-ppi y-ppi size ratio
--------------------------------------------------------------------------------------------
   1     0 image    3508  2480  rgb     3   8  jpeg   no         8  0   300   300  409K 1.6%

How to register a personal device on the wired network at Imperial College London

How to register a personal device on the wired network at Imperial College London

Useful if your machine's OS isn't pre-loaded with an Operating System with a web-browser(!)

Alternatively, you can contact ICT self-service.

Information required:

  • IP address of device (as assigned by the pre-registration network, 172.nnn.nnn.nnn, IP_ADDRESS in the below command)
  • MAC Address of device (xx:xx:xx:xx:xx:xx, MAC_ADDRESS in the below command)
  • Your college username and password (USER_NAME below, you will be prompted for the password)
