picslabels Documentation

picslabels - Lists or modifies image labels
PROGRAMMER: TSTOEWE
Handles image disk labels, which contain the home block, histogram area,
keyword label area and the processing history text area. The homeblock
area contains information about the image such as image size, bit type
and pointers to the other label areas. The histogram area contains a
histogram of the image. The keyword label area contains information
needed to process the image.  Keywords are in the form,
'keyword=keyvalue'.  An example,
                     TARGET=MIRANDA.
The processing history text area contains a list of the processing which
has been done on the image and some parameters.  LABELS allows you to
print these label areas, add information to the keyword or processing
history text area, initialize the histogram, keyword or processing
history text area, or delete a keyword from the keyword label area.
See the PICS manual appendix for more information about the image
labels.
