snapscreenshot is *fast*, when compared to fbdump and fbcat. However,
|
|
the reason it's so fast is that it doesn't read the graphic content of
|
|
the framebuffer. Instead, the text content of the screen is read (from
|
|
the /dev/vcs* devices) and rendered in the current console font... which
|
|
is the current font of the console you executed snapscreenshot from,
|
|
*not* the font in the console you're taking a snapshot of!
|
|
|
|
Also, custom fonts just don't work well with snapscreenshot. Depending
|
|
on the font, you may get an error (GIO_FONTX), a segmentation fault,
|
|
or else the resulting screenshot is garbled.
|
|
|
|
Because /dev/vcs* is used, snapscreenshot does NOT work for taking
|
|
screenshots of software that actually uses the framebuffer for graphics,
|
|
e.g. fbpdf, feh, "mplayer -vo fbdev", "links -g -driver fb". For these,
|
|
use fbcat or fbdump instead.
|
|
|
|
By default, the text on all the consoles ends up in the output image. To
|
|
take a shot of only one console, use a command like:
|
|
|
|
# snapscreenshot --firstwin 1 -c1 -x1 > shot.tga
|
|
|
|
...or use this:
|
|
|
|
# snapscreenshot.cur > shot.tgz
|
|
|
|
The snapscreenshot.cur script was written by the SlackBuild author,
|
|
and is not part of snapscreenshot itself.
