Hi there,
I have some issues concerning tx_fax and rx_fax.
I use AsterFax to send my fax, but I am pretty sure that AsterFax is not the causer of this problem.
Asterisk sends the fax I transmit via AsterFax, but the fax allways lookes jolted.
The papersize I use is a4.
I tried to find the bug / misconfiguration by myself and found out that there seems to be a problem with the tiff file I send.
At first this was hard to find, because with the windows tool my tiff file allways looked correct. But when opening it with the gimp I got the same jolted view, the fax machine prints out.
So I used tiffdump to get more information of this tiff file.
Here is a part of the result:
Magic: 0x4949 <little-endian> Version: 0x2a
Directory 0: offset 7996 (0x1f3c) next 15974 (0x3e66)

[...]After this I dumped the information of an tiff file, which is displayed correctly by gimp.
This is an extract out of this dump:

[...]As you can see, there is a different width and height and width than on the wrong tiff. I am not really sure why tx_fax creates the file with this values,
but I am pretty sure that this could be the solution to my problem.
Is there any possibility to tell tx_fax an papersize?
I am using asterisk 1.2.14, spandsp 0.0.2 pre26, libtiff 3.7.1
and asterfax 1.0. OS is OpenSuse 10 64-bit.
I really hope that you have a solution for my problem.
