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]

command:

-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)
command:

Code

grab -d -j 100 /tmp/shot1.jpg

FTP to /tmp to retrieve your file

The results are perfect

Enjoy!

Ten,
How do you show it in your thread window not like this below

Sorry I misunderstood the your question chris so scrap my last answer that I just deleted! - to put an image in the thread window you need to register with imageshack or a similar service - upload the image to there, and then click on the insert image icon on the toolbar above where you are writing your post, select "from URL" - enter the address of the uploaded imageshack link, and uncheck "Retrieve remote file and reference locally".

you can also use this command if you want to take a screenshot of the OSD but dont want the TV channel as well.

grab -o -p /tmp/grab.png

you can also make a screen grab via your browser.

With photo bucket or image shack you can just copy the image code straight into your post without using the add image button.

Nice one G
