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.
