img2txt

img2txt(1)						      General Commands Manual							img2txt(1)

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.
