Answer 1

Type this to extract the layer number 2 from a PSD file:

convert             \
  <filename>.psd[0] \
  <filename>.psd[2] \
  \(                    \
     -clone 0           \
     -alpha transparent \
  \)                    \
 -swap 0           \
 +delete           \
 -coalesce         \
 -compose src-over \
 -composite        \
 <extracted-filename>.png

This creates first a transparent canvas with the same size of the PSD file, then combines it with the layer 2 keeping it's original layout (-coalesce)

Answer 2

I use this command line to do what are describing:

convert.exe <filename>.psd -set dispose Background -coalesce <outfilename>.png
