fbdump (captures the visible portion of framebuffer to stdout)
|
||||
|
||||
fbdump is a simple tool that captures the contents of the visible portion of
|
||||
the Linux framebuffer device and writes it to the standard output as a PPM
|
||||
file. In other words, it takes a screenshot of anything running on the
|
||||
framebuffer. It currently has fairly complete support for packed-pixel
|
||||
framebuffer types and also works with the VGA16 framebuffer driver.
|
||||
|
||||
To get a popular image format, issue a command like
|
||||
'fbdump | pnmtopng > shot.png'
|
||||
To get a popular image format, issue a command like:
|
||||
|
||||
fbdump | pnmtopng > shot.png
|
||||
|
||||
Note: fbdump is rather slow on modern systems with high-resolution
|
||||
framebuffers at 32-bit color depth. On the maintainer's system, it takes
|
||||
8 seconds to dump a 1920x1080x32 framebuffer. Be patient.
