[kde-linux] HTML previews

[albert.bradley at contractor.thomson.com]

Thanks for getting back again....

I think this answer might work, but I'm having trouble getting it to capture from the window ID I'm getting for the Firefox window.  Note that capturing the 'previewtest' window DOES work.  (see below output)

???

Also, I notice that although firefox advertises -width and -height parameters for the command line, it seems to ignore them (on all platforms I have tried)

Thanks again.

The preview is only suitable for previews :)
For better images you'll always need the output of a full rendering engine 
and, if I understand correctly, if you also want plugin output, you will need 
a screen capture

One of the ImageMagick commandline tools can do screenshots (full screen or of 
any window). It is called "import"
