pnmpaste
Paste one PNM image onto another
TLDR
Paste image onto another
$ pnmpaste [small.pnm] [x] [y] [background.pnm] > [output.pnm]
Paste at top-left$ pnmpaste [overlay.pnm] 0 0 [base.pnm] > [output.pnm]
Replace operation$ pnmpaste -replace [patch.pnm] [100] [50] [image.pnm] > [output.pnm]
OR operation$ pnmpaste -or [mask.pbm] [x] [y] [image.pnm] > [output.pnm]
SYNOPSIS
pnmpaste [options] from x y to
DESCRIPTION
pnmpaste pastes one PNM image onto another at a specified position. Multiple paste operations (replace, or, and, xor) allow for different compositing effects.
Part of Netpbm for image compositing.
PARAMETERS
from
Image to paste.x, y
Position in target image.to
Background image.-replace
Simple replacement (default).-or
Bitwise OR.-and
Bitwise AND.-xor
Bitwise XOR.
EXAMPLES
$ # Paste logo at position 10,10
pnmpaste logo.ppm 10 10 background.ppm > result.ppm
# Paste at bottom-right (compute position)
pnmpaste small.ppm 300 200 large.ppm > result.ppm
# Combine with masks
pnmpaste -or mask.pbm 0 0 image.pbm > masked.pbm
# Multiple pastes
pnmpaste img1.ppm 0 0 base.ppm | pnmpaste img2.ppm 100 0 - > result.ppm
pnmpaste logo.ppm 10 10 background.ppm > result.ppm
# Paste at bottom-right (compute position)
pnmpaste small.ppm 300 200 large.ppm > result.ppm
# Combine with masks
pnmpaste -or mask.pbm 0 0 image.pbm > masked.pbm
# Multiple pastes
pnmpaste img1.ppm 0 0 base.ppm | pnmpaste img2.ppm 100 0 - > result.ppm
CAVEATS
Pasted image must fit within background. Use negative coordinates for offset. Part of Netpbm.
HISTORY
pnmpaste is part of Netpbm by Jef Poskanzer, providing basic image compositing.
