SYNOPSIS

scr2txt [-a] [-l]

DESCRIPTION

The scr2txt utility reads a video memory dump, such as that created by the vidcontrol(1) utility, and converts it to plain text representation of the text from the screenshot.

scr2txt appends a newline character to the end of each line.

scr2txt reads from the standard input, and writes to the standard output.

The following options are available:
-a Emit ANSI colour escape codes to recreate the colours of the original screenshot.
-l Replace any eight-bit line drawing characters with their closest seven-bit equivalents. This may result in odd output depending on the font in use when the screenshot was taken.

See vidcontrol(1) for information about the input file format expected by scr2txt.

RETURN VALUES

The scr2txt utility exits 0 on success or >0 if an error occurred.

EXAMPLES

The command sequence:

 vidcontrol -p < /dev/ttyv0 > shot.scr

 scr2txt < shot.scr > shot.txt

will capture the contents of the first virtual terminal, and redirect the output to the shot.scr file. scr2txt then processes this file, and writes the output to shot.txt. Of course this could be rewritten as


 vidcontrol -p < /dev/ttyv0 | scr2txt > shot.txt

This example will take a snapshot and remap the line drawing characters.


 vidcontrol -p < /dev/ttyv0 | scr2txt -l > shot.txt

BUGS

When remapping eight bit characters to seven bit characters, scr2txt should have more than one lookup table, depending on the font in use, and should be able to process a custom lookup table provided by the user.
