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.

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.
SEE ALSO rpict(1)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 :-)

Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
