png2html(1)						      General Commands Manual						       png2html(1)

NAME

       png2html - transforms a PNG image to a web page

SYNOPSIS

       png2html [ imagefile.png textfile.txt output.html compatibility ]
       Where compatibility is either 0, 1 or 2
       0 = Small Source, but uncompatibile with some browsers
       1 = Medium Size, works with almost anything.
       2 = Large Source, strict HTML.

DESCRIPTION

       png2html takes a PNG image and transforms it pixel by pixel to a web page, encoding each pixel as an appropriately coloured letter.
       It is decided which letter to encode each pixel as by using a text file supplied by the user.

NOTES

       This program assumes that 1 pixel should equal 1 character.
       But  characters	are  taller  than  they are wide, so you may want to resize the image first, else the output image will be taller than the
       original. Resizing is also advisable as letters are larger than pixels.
       Setting the output file to be "-", will direct the output to stdout; setting the text file to "-" will  cause  the  program  to	read  from
       stdin.

NAME

       vinvert - invert image pixel values

SYNOPSIS

       vinvert [option ...] [infile] [outfile]

DESCRIPTION

       vinvert inverts each input image to produce a corresponding output image. The operation is suitable for swapping black and white in a grey-
       scale image.

       Each output pixel is computed from the corresponding input pixel by

	      out-pixel = M - in-pixel

       where M is the maximum value allowed by the pixel representation, or 1 in the case of float or double pixels. Input pixel values  must  lie
       in the range [0,M].

       Each output image has the same number of bands, rows and columns, and the same pixel representation, as the corresponding input image.

COMMAND LINE OPTIONS

       vinvert accepts the following options:

       -help	      Prints a message describing options.

       -in infile     Specifies a Vista data file containing the input images.

       -out outfile   Specifies where to write the output images as a Vista data file.

       Input and output files can be specified on the command line or allowed to default to the standard input and output streams.
