RA_PICT(1)
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 spec
- ified, 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 spec
- ified, 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 exercise
for the reader :-)
