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 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 vidcon-
	      trol(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
