Developing a Fax Application

The second method uses the normal TIFF sending functions to
transmit a TIFF file that is preceded or succeeded by other G3 or
ASCII files that are transmitted with either the
noninfopkt-formatted raw data fax functions or the TIFF file fax
functions.
To use the second method successfully, the user must pay attention
to the combine argument of the BfvFaxNextPageTiff function (see
the function description in Volume 4, Fax Processing, Bfv API
Reference Manual for detailed information). When the combine
argument is 1, the page information for the TIFF G3 data is sent to
the channel without beginning a new page (do not call the
BfvFaxStripParams function to do this).
For example, a program to send a page composed of ASCII combined
with G3 from a TIFF file that is combined with G3 from a raw file
could look like this:
/* Set up call prior */
/* Begin fax transmission, normal resolution, */
/* normal width */
BT_ZERO(args_fax);
args_fax.resolution = RES_200H_100V;
args_fax.width = WIDTH_A4;
BfvFaxBeginSendRaw(lp, &args_fax);
BfvFaxGetRemoteInfo(lp, &args_fax);
BfvFaxWaitForTraining(lp, &args_fax);
BT_ZERO(args_fax);
args_fax.fname = "ascii_file";
args_fax.fmt = DATA_ASCII;
BfvFaxSendFile(lp, &args_fax);
BT_ZERO(args_tiff);
args_tiff.fname = "tiff_file";
args_tiff.fmode = "r";
tp = BfvTiffOpen(&args_tiff);
/* No BfvFaxStripParams call is needed here, */
/* due to a combine value of 1 */
BT_ZERO(args_fax);
args_fax.s_tp = tp;
args_fax.combine = 1;
BfvFaxNextPageTiff(lp,&args_fax);
BT_ZERO(args_fax);
args_fax.s_tp = tp;
BfvFaxSendPageTiff(lp,&args_fax);
BT_ZERO(args_tiff);
args_tiff.tp = tp;
BfvTiffClose(&args_tiff);
