Appendix A
G3 Legacy Utilities
This appendix describes legacy utilities that help manipulate raw
G3 fax files.
The utilities described in this chapter permit you to manipulate
raw G3 fax files (rather than infopkt-formatted files) from the
command line. These are legacy utilities that are provided to
users who need to manipulate raw G3 files. They have been
tested with previous versions of the Bfv API and are expected to
work, but they are no longer tested/supported.
Output files will usually contain a 128-byte Brooktrout header.
When you create an infopkt file using one of these output files,
you must either use the BTG3 type infopkt or remove the
header.
For input files, the 128-byte Brooktrout header is optional.
However, a header can provide crucial information to the
utilities about resolution and image width. This information is
particularly important to the Print utility.
The G3 utilities only support the resolutions 200H x 100V
(Normal) and 200H x 200V (Fine). They do not support any of
the higher resolutions.
All utilities except for the G3 conversion utility use file names
with the .3XX extension. The first page of a fax has the extension
.301, the second .302, etc. Many of these utilities will ignore
actual extensions supplied and add or convert to these
extensions.
