20     .SH DESCRIPTION
21     .B Ra_pict
22     converts a Radiance picture, as produced by
23     .B rpict
24     (1) to a Macintosh PICT file. The picture will be a 24 bit PICT 2 picture,
25     using a single bit map (DirectRect).
26     .SH OPTIONS
27     .TP 10n
28     .BI \-g " gamma"
29     This sets an explict gamma correction for the image. If it is not
30     specified, the default value of 2.0 is used.
31     .TP
32     .B \-v
33     Invokes verbose mode, and gives line on standard error giving the
34     size of the picture and the gamma correction used.
35     .TP
36     .BI "\-e +/\-" " stops"
37     Adjusts the exposure by stops.
38     .TP
39     .I infile
40     Specifies the file to read the picture from. If none is specified,
41     it takes it from standard input. If standard input is used, then
42     the picture is sent to standard output.
43     .TP
44     .I outfile
45     Specifies the file to send the PICT file to. If none is specified,
46     it is sent to standard output.
47     .SH EXAMPLES
48     .PP
49     ra_pict mypict.pic mypict.pict
50     .PP
51     Will convert the Radiance picture mypict.pic, giving the Macintosh
52     PICT mypict.pict.
53     .PP
54     ra_pict -g 2.2 mypict.pic mypict.pict
55     .PP
56     Will convert the file using a gamma of 2.2.
57     .SH "SEE ALSO"
58     rpict(1)
59     .SH BUGS
60     Does not yet do Macintosh PICT to Radiance PIC, as this PICT files
61     are a lot more complex than just one bit map. This is left as an
62     exercise for the reader :-)
