Tutorial - Grab A Screenshot Using Telnet


Most users will hardly ever need to use the screenshot function of the E2 web interface, but as someone who does almost daily i have found occasionally it does not want to play. So here is a workaround giving better results using telnet should you ever need it.


To take a screenshot using telnet we use the grab command, here are the options
Usage: grab [commands] [filename]

commands:


-o only grab osd (framebuffer) when using this with png or bmp

fileformat you will get a 32bit pic with alphachannel

-v only grab video

-d always use osd resolution (good for skinshots)

-n dont correct 16:9 aspect ratio

-r (size) resize to a fixed width, maximum: 1920

-l always 4:3, create letterbox if 16:9

-b use bicubic picture resize (slow but smooth)

-j (quality) produce jpg files instead of bmp (quality 0-100)

-p produce png files instead of bmp

-h this is the help screen

If no command is given the complete picture will be grabbed.
If no filename is given /tmp/screenshot.[bmp/jpg/png] will be used.

Here is an example using DCC


grab jpg with skin osd resolution (good for skinshots)
