Just tried it, works! :-)
Is it possible to resize before paste and preserve the original width/ height
of the image? So keeping the width/ height + resize -2*$BORDER?
Something like:
./oiiotool /Volumes/Build/test/test-75.jpg --pattern
constant:color=0.2,0.2,0.2,1.0 "{TOP.width}x{TOP.height}" "{TOP.nchannels}"
—-resize “{TOP.width-2*40}x{TOP.height-2*40}” --paste "+40+40” -o
/Volumes/Build/test/test_frame.png
