img2txt - convert images to various text-based coloured files


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


   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.


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

   -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.


   img2txt hello.jpg > hello.ans

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


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

   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.
