Having trouble finding a way that would reposition layer 0 via -geometry -repage before placing it on underlay...

How can I keep this as one command to position the edits made to artwork.png and resize and position before merging down?

Code: Select all

convert \
\( artwork.png -gravity center -extent 2000x2000 -fuzz 9% -transparent white \)          \
alpha.png -gravity center -alpha On -compose copy_opacity -composite                     \
-fuzz 9% -transparent white -thumbnail 1900x1900 -repage -400+0 -compose DstOver         \
underlay.png altered.png

The end of your command probably doesn't do what you want.

"-compose DstOver" is a setting, but isn't followed by anything that uses the setting.

Before you write the output "altered.png", you read another input, "underlay.png". So there will be two outputs.

Perhaps you mean (?)

Code: Select all

convert \
\( artwork.png -gravity center -extent 2000x2000 -fuzz 9% -transparent white \)          \
alpha.png -gravity center -alpha On -compose copy_opacity -composite                     \
-fuzz 9% -transparent white -thumbnail 1900x1900 -repage -400+0                          \
underlay.png -compose DstOver -composite altered.png

At least that has proper syntax and will produce 1 output (as per what snibgo wrote above)
