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. |
