[magick-users] exporting psd layers

[Jacky J]

I'm trying a simple command of
convert in.psd out.png

it creates a file for each layer. However, each png file is not the same 
size as the psd. It's as if convert.exe is autocropping each layer based 
off transparency.

So if i have a 256x256 psd, i want each png file to be 256x256 
regardless, oriented just the way it is in the psd. Any way to do this? 
I've played with -resize, -size, -geometry, -crop, -page to no avail.

Thanks
