TkScanFax is a TCL/Tk GUI fax program in ANSI C/POSIX with support for efax and multiple languages. It helps make the cover page, convert text files, PostScript files, and image files into fax files, and send faxes. It also uses scanners by using backends such as SANE. The efax program supports Class-1 faxmodems.
fax2png extracts a specified page from a 1-bit black and white TIFF image, such as a fax, and efficiently converts it to PNG format without the performance overhead of netpbm-based solutions. Antialiasing is supported to produce attractive reductions to typical Web browser widths. 90-degree-interval rotations and flips are also supported.
