ra_pict [ -e +/- stops ] [ -v ] [ -g gamma ] [ infile [
outfile ]]
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).
-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.
ra_pict mypict.pic mypict.pict
Will convert the Radiance picture mypict.pic, giving the
Macintosh PICT mypict.pict.
ra_pict -g 2.2 mypict.pic mypict.pict
Will convert the file using a gamma of 2.2.
rpict(1)
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 :-)
