TIFF compression format and TIFF resolution

When saving a fax into TIFF format, you can select type of TIFF compression. Fax Voip T.38 Console can convert faxes into TIFF using the following TIFF compression formats:

• PACKBITS
• CCITTFAX3
• CCITTFAX4
• LZW
• NO COMPRESSION

You can also use Convert to standard resolution (204*196 dpi) graphics option when saving TIFF files originally created with resolution 204*98 dpi. This can be useful, as some viewers may incorrectly display TIFF files in draft quality (204*98 dpi).

To do additional settings, follow these instructions:

1.     Open Fax Voip T.38 Console.

2.     In the Fax Voip T.38 Console, open the Outbox folder, Inbox folder or Fax-on-Demand folder.

3.     In the details pane, right-click the fax, and then click Save As.

4.     In the Save As... dialog, in the Save as type: field, select Faxes(*.tif) as the format to which you want to convert the document. Then specify a file name (by default the unique file name generated by the program is used).

5.     Uncheck the Use original TIFF format option, then click Settings button.

6.     In the TIFF properties dialog, in the Compression format pane, select the desired format of TIFF compression. You can select between the following options: PACKBITS, CCITTFAX3, CCITTFAX4, LZW or NO COMPRESSION.

7.     Check Convert to standard resolution (204x196 dpi) graphics option if you want to save your TIFF in the 204x196 dpi resolution.

8.     Click OK to save settings.

9.     When you make all necessary settings, in the Save As... dialog, click Save button.

Notes

• Received faxes initially stored in the CCITTFAX4 TIFF format.
• Outgoing faxes generated by the Fax Voip Virtual Printer, originally stored in the CCITTFAX3 TIFF format.
• When converting into PDF format, the CCITTFAX4 TIFF compression always used.
• When you save a fax into TIFF file with different compression formats, Windows TIFF filters are used. You can view the saved TIFF files using Windows Photo Viewer. Nevertheless, the correct viewing in any TIFF viewer or correct using with any fax program not guaranteed. Note that even different versions of Windows can understand the same TIFF compression format in different ways.
