Hi Fred,
the -gravity parameter has no effect.
The order of the parameters affects the resulting image. Do you know why ?
If I call:
convert document.pdf -density 240 -compress none -page A4 image.tif
I get a:
Image Width: 554 Image Length: 123
Resolution: 240, 240
and the keyword -page a4 seems not to work.
But if I call:
convert -density 240 -compress none -page A4 document.pdf image.tif
I get a:
Image Width: 1983 Image Length: 2807
Resolution: 240, 240
and this is an a4 page image.
I've also tried in 2 steps, first I rasterized and got a 554x123 image and
then I tried to pad and get an a4 image but unsuccessfully.
I know that there is a new version with the -extent parameter that should do
what I need.
The problem is that I need an a4 uncopressed image at 240 dpi that I will
convert into afp data stream, because our mainframe fax accepts only this
format.
