|
|
|
|
- Set the horizontal alignment of the overlay:
|
|
|
|
`pamcomp -align {{left|center|right|beyondleft|beyondright}} -xoff {{x_offset}} {{path/to/overlay.pam}} {{path/to/underlay.pam}} > {{path/to/output.pam}}`
|
|
|
|
- Set the vertical alignment of the overlay:
|
|
|
|
`pamcomp -valign {{top|middle|bottom|above|below}} -yoff {{y_offset}} {{path/to/overlay.pam}} {{path/to/underlay.pam}} > {{path/to/output.pam}}`
|
|
|
|
- Set the opacity of the overlay:
