Hello Konrad,

thanks for the part of your script.

In principle it works well. But in my tests the new generated pdf-file 
doesnt fit to an A4-page-size. The size is reduced around 4-fold an when 
I sent the document via hylafax one could not read anything.

Also I had problems with the monocrome attribut from the convert-tool 
with multible-page documents. I couldn't open the generated pdf-document.

Another question is that I dont know in which config-file of hylafax I 
have to add the code.

Thanks for help :-)

Best regards, Alex
