ppmtopict – convert a portable pixmap into a Macintosh PICT file
Reads a portable pixmap as input. Produces a Macintosh PICT file as
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
Even though PICT supports 2 and 4 bits per pixel, ppmtopict always gen‐
erates an 8 bits per pixel file.
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. However
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.
