NAME

       img2txt - convert images to various text-based coloured files

SYNOPSIS

       img2txt [ -W width ] [ -H height ] [ -x font-width ] [ -y font-height ]
               [ -b brightness ] [ -c contrast ] [ -g gamma ]
               [ -d dither ] [ -f format ] FILE

DESCRIPTION

       img2txt converts images to colour ASCII characters and outputs them to text-based coloured files.

       img2txt can load the most widespread image formats: PNG, JPEG, GIF, PNG, BMP etc (see NOTES for details).
       By default the output text is 60 columns wide, and the line count  is  computed  accordingly  to  respect
       aspect ratio of original file.  The default output format is standard ANSI coloured text.

OPTIONS

       -W, --width=<width>
              Change output column count. If not given, the default is set to 60.

       -H, --height=<height>
              Change output line count. If not given, the height is computed to match correct aspect ratio.

       -x, --font-width=<width>
              Change  output  font  width.  If  not  given, the default is set to 6. This value will be used for
              computing aspect ratio.

       -y, --font-height=<height>
              Change output font height. If not given, the default is set to 10. This value  will  be  used  for
              computing aspect ratio.

       -b, --brightness=<brightness>
              Change image brightness. Default to 1.0.

       -c, --contrast=<contrast>
              Change image contrast. Default to 1.0.

       -g, --gamma=<gamma>
              Change image gamma. Default to 1.0.

       -d, --dither=<dither>
              Change dithering algorithm. This can be one of the following (default to fstein) :
                none     : Nearest color
                ordered2 : Ordered 2x2
                ordered4 : Ordered 4x4
                ordered8 : Ordered 8x8
                random   : Random
                fstein   : Floyd Steinberg

       -f, --format=<format>
              Change output format. This can be one of the following (default to ansi) :
                ansi   : coloured ANSI
                caca   : internal libcaca format
                utf8   : UTF8 with CR
                utf8cr : UTF8 with CRLF (MS Windows)
                html   : HTML with CSS and DIV support
                html3  : Pure HTML3 with tables
                irc    : IRC with ctrl-k codes
                bbfr   : BBCode (French)
                ps     : Postscript
                svg    : Scalable Vector Graphics
                tga    : Targa Image

       -h, --help
              Display help message and exit.

       -v, --version
              Display version of the program and exit.

EXAMPLES

       img2txt hello.jpg > hello.ans

       img2txt --width=40 --format=svg hello.jpg > tinyhello.svg

NOTES

       Setting both column and line count (using --width and --height) will let you choose the exact output size
       without taking aspect ratio in account.

       You must compile libcaca package with support of Imlib2 to be able  to  load  a  wide  variety  of  image
       formats. Otherwise you will only  be able to load regular BMP files.
