The Receive Tab

The Receive dialog tab controls where and in what image type incoming faxes are saved.

1. Select a channel or range of channels from the Overview tab.
2. Click the Properties button to view the properties associated with the selected channel(s).
3. Click the Receive tab.

Figure 69. Properties for Selected Fax Channels - Receive Tab

The Receive dialog controls where and how faxes are received for the selected channel(s). The Receive File area contains the Receive File Name Path user entry box. This sets the GFXRECVPATH command in the registry key and specifies where incoming fax files should be saved. This command defines both the directory in which received files are placed and the filename template to be used. The default directory path is c:\Fax\.

The default file naming convention is shown below:

x001P001.tif - where x represents the first 26 channels

xa001P001.tif - where xa represents channels 27 and higher.

Use the Browse button to navigate or enter the fully qualified path name.

The Receive File Type area contains four radio control buttons that select the image format in which to save the received fax:

Use Receive Encoding

Turning on this button saves the file in the same format used during transmission by the remote fax machine. For non-ECM fax transmissions, this may include bad scan lines.

The software maintains facsimile data in a TIFF (Tagged Image File Format) compression format. The TIFF header describes the data in the file, and helps to distinguish facsimile image files from other types of image files.

GDK supports TIFF Type 3 and TIFF Type 4 compression formats. TIFF Type 3 is compatible with ITU Group 3 T.4 recommendation. Select either 1-D (one-dimensional) or 2-D (two-dimensional) Modified Huffman (MH) encoding compression.

TIFF Group 3 1-D (MH)	Turning this button on saves each incoming fax as a TIFF Group 3 1-D (MH) file. Each image line is encoded as a TIFF type 3 1-D line with EOL codes after each scan line and the TIFF file is terminated with six EOLs to indicate the end of the page. The fill order can be MSBF (most significant bit first) or LSBF (least significant bit first). The default is LSBF. Selecting this option adds the GFXFORM line and associated value to the registry key.
TIFF Group 3 2-D (MR)	Turning this button on saves each incoming fax as a TIFF Group 3 2-D file. These files are also called "Modified READ" (MR) files. The first image line of these files is encoded as a TIFF 3 1-D line. A certain number of lines, usually one to three, follow the 1-D line and encode the differences between the current and previous lines. Following the 2-D lines is another 1-D line. Then, there are more 2-D lines based on this new reference line. A flag indicates whether a line is complete in itself (a 1-D encoded line) or is based on the preceding line (a 2-D encoded line) and is embedded in the end of line code. This encoding scheme results in approximately a 15 to 20 percent reduction in file size over 1-D encoding in most cases. This can vary greatly, depending on the type of image. A failure in one line affects only a small portion of the document. Selecting this option adds the GFXFORM lines and associated value to the registry key.
TIFF Group 4 (MMR)	Saves each incoming fax as a TIFF Group 4 file. These files are also called "Modified Modified READ" (MMR) files. An imaginary white line precedes the first line. Every line in the file is based on the differences between the current line and the line that preceded it; the first line presumes a blank line preceded it. This byte-oriented compression scheme results in approximately a 20 to 40 percent reduction in file size over one-dimensional encoding in most cases. A scan line error can corrupt an entire image from the point of the error forward. Selecting this option adds the GFXFORM with the appropriate value.
