Margin in command line

Hi Guys, this is my first question and I hope you could help me...

We had to migrate to a newer version (the last one) of PDFCreator...
Our project used to create PDF with the old 1.7 version..

We create it using the Images2PDF console application with parameters as is:

/i "C:\Export\test.jpg" /e "C:\Export\test.pdf" /ps A4 /po Landscape /bo 10 10 10 10

but it seems that the /bo parameter doesn't work...

Do you have any idea if there is a format change or something else ?

Thanks for you help.
