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.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.

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 :-)
