NAME

       ppmtopict - convert a portable pixmap into a Macintosh PICT file

SYNOPSIS

       ppmtopict [ppmfile]

DESCRIPTION

       Reads a portable pixmap as input.  Produces a Macintosh PICT file as output.

       The  generated  file  is  only the data fork of a picture.  You will need a program such as mcvert to generate a Macbinary or a BinHex file
       that contains the necessary information to identify the file as a PICT file to MacOS.

       Even though PICT supports 2 and 4 bits per pixel, ppmtopict always generates an 8 bits per pixel file.

BUGS

       The picture size field is only correct if the output is to a file since writing into this field requires seeking backwards on a file.  How-
       ever the PICT documentation seems to suggest that this field is not critical anyway since it is only the lower 16 bits of the picture size.

NAME

       ra_pict - convert Radiance pictures to Macintosh PICT files

SYNOPSIS

       ra_pict [ -e +/- stops ] [ -v ] [ -g gamma ] [ infile [ outfile ]]

DESCRIPTION

       Ra_pict	converts a Radiance picture, as produced by rpict (1) to a Macintosh PICT file. The picture will be a 24 bit PICT 2 picture, using
       a single bit map (DirectRect).

OPTIONS

       -g gamma  This sets an explict gamma correction for the image. If it is not specified, the default value of 2.0 is used.

       -v	 Invokes verbose mode, and gives line on standard error giving the size of the picture and the gamma correction used.

       -e +/- stops
		 Adjusts the exposure by stops.

       infile	 Specifies the file to read the picture from. If none is specified, it takes it from standard input. If standard  input  is  used,
		 then the picture is sent to standard output.

       outfile	 Specifies the file to send the PICT file to. If none is specified, it is sent to standard output.

EXAMPLES

	   ra_pict mypict.hdr mypict.pict

       Will convert the Radiance picture mypict.hdr, giving the Macintosh PICT mypict.pict.

	   ra_pict -g 2.2 mypict.hdr mypict.pict

       Will convert the file using a gamma of 2.2.

BUGS

       Does  not  yet do Macintosh PICT to Radiance PIC, as this PICT files are a lot more complex than just one bit map. This is left as an exer-
       cise for the reader :-)
