SCR2PNG(1) BSD General Commands Manual SCR2PNG(1)NAMEscr2png — convert a video memory dump to a PNG image
SYNOPSISscr2png [-f font-file] [-v]
DESCRIPTION
The scr2png utility reads a video memory dump, such as that created by
the vidcontrol(1) utility, and converts it to a PNG image, using the font
file specified by the user, or a default font if none is specified.
scr2png reads from the standard input, and writes to the standard output.
The following options are available:
-f font-file
Use the font read from font-file when rendering characters on to
the image. scr2png reads the same font files used by the
vidcontrol(1) utility. The default font file is
/usr/share/syscons/fonts/cp850-8x16.fnt.
-v Use a VGA adapter palette. The default colours used by scr2png
match those used by many X11 terminal implementations. However,
they do not closely match those used by a typical VGA adapter.
Use -v and the colours are more likely to match those originally
displayed.
See scrshot(1) for information about the input file format expected by
scr2png.
RETURN VALUES
The scr2png utility exits 0 on success or >0 if an error occurred.
EXAMPLES
The command sequence:
vidcontrol -p < /dev/ttyv0 > shot.scr
scr2png < shot.scr > shot.png
will capture the contents of the first virtual terminal, and redirect the
output to the shot.scr file. scr2png then processes this file, and
writes the output to shot.png. Of course this could be rewritten as
vidcontrol -p < /dev/ttyv0 | scr2png > shot.png
This example captures a screen shot, and then produces two different PNG
images using different fonts.
vidcontrol -p < /dev/ttyv0 > shot.scr
scr2png < shot.scr > shot-1.png
scr2png-f /usr/share/syscons/fonts/cp850-8x14.fnt < shot.scr > shot-2.png
