SCR2PNG(1) General Commands Manual SCR2PNG(1) NAME scr2png -- convert a video memory dump to a PNG image SYNOPSIS scr2png [-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 speci- fied. scr2png reads from the standard input, and writes to the stan- dard 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 SEE ALSO scr2txt(1), vidcontrol(1), syscons(4) AUTHORS Nik Clayton <nik@FreeBSD.org> FreeBSD Ports 14.quarterly May 18, 2001 SCR2PNG(1)
